It's similar to when you visit a hotel, you want breakfast, lunch & dinner in the suitable timings, right?f = io.StringIO() with redirect_stdout(f): help(pow) s = f.getvalue() To send the output of help() to a file on disk, redirect the output to a regular file:@Override public AssetManager getAssets() { return mBase.getAssets(); } mBase is simply a field set by the constructor to a specific context. So a context is wrapped and the ContextWrapper delegates its implementation of the getAssets method to that context. Let’s get back to examining the Activity class which ultimately inherits from Context to see how this all works. 88 Context is an "interface" to the global information about an application environment. In practice, Context is actually an abstract class, whose implementation is provided by the Android system. A context must only be made current on a single thread at a time and each thread can have only a When moving a context between threads, you must make it non-current on the old thread before..

The context is modelled as a stack of Javascript objects, arrays, and literals. Dust can search multiple layers of the stack, popping off the top objects and looking below. In this example, notice how Dust.. getBaseContext() -- gives the context of the Activity that is set (created) by the constructor of activity. getApplicationContext() -- gives the Context setup (created) during the creation of application. You probably know what an Activity is, but to review - it’s basically 'a single thing the user can do. It takes care of providing a window in which to place the UI that the user interacts with'. Developers familiar with other APIs and even non-developers might think of it vernacularly as a “screen.” That’s technically inaccurate, but it doesn’t matter for our purposes. So how do Activity and Context interact and what exactly is going in their inheritance relationship? 4 The Context is the android specific api to each app-s Sandbox that provides access app private data like to resources, database, private filedirectories, preferences, settings ... Canceling this context releases resources associated with it, so code should call cancel as soon as the operations running in this Context complete:

The oncontextmenu event occurs when the user right-clicks on an element to open the context menu. Note: Although the oncontextmenu event is supported in all browsers, the contextmenu attribute is.. And in order for Android to do this, it needs access to information that is supplied by Context. Specifically, the system needs to access to a ContentResolver so it can “determine the MIME type of the intent’s data". This whole bit about how startActivity makes use of context was a bit complicated and I don’t fully understand the internals myself. My main point was just to illustrate how application-wide resources need to be accessed in order to perform many of the operations that are essential to an app. Context is what provides access to these resources. A simpler example might be Views. We all know what you create a custom View by extending RelativeLayout or some other View class, you must provide a constructor that takes a Context as an argument. When you instantiate your custom View you pass in the context. Why? Because the View needs to be able to have access to themes, resources, and other View configuration details. View configuration is actually a great example. Each Context has various parameters (fields in Context’s implementations) that are set by the OS itself for things like the dimension or density of the display. It’s easy to see why this information is important for setting up Views, etc.@track_entry_and_exit('widget loader') def activity(): print('Some time consuming activity goes here') load_widget() Note that there is one additional limitation when using context managers as function decorators: there’s no way to access the return value of __enter__(). If that value is needed, then it is still necessary to use an explicit with statement. org.springframework.context. Interface ApplicationContext. All Superinterfaces Inheritance from a parent context. Definitions in a descendant context will always take priority

The upshot is that Context is what enables access to system resources and its what hooks components into the “greater app". Let’s look at the subclasses of Context, the classes that provide the implementation of the abstract Context class. The most obvious class is the Activity class. Activity inherits from ContextThemeWrapper, which inherits from ContextWrapper, which inherits from Context itself. Those classes are useful to look at to understand things at a deeper level, but for now it’s sufficient to know that ContextThemeWrapper and ContextWrapper are pretty much what they sound like. They implement the abstract elements of the Context class itself by “wrapping” a context (the actual context) and delegating those functions to that context. An example is helpful - in the ContextWrapper class, the abstract method getAssets from the Context class is implemented as follows: 4 Context means component (or application) in various time-period. If I do eat so many food between 1 to 2 pm then my context of that time is used to access all methods (or resources) that I use during that time. Content is an component (application) for particular time. Context of components of application keeps changing based on the underlying lifecycle of the components or application. For instance, inside the onCreate() of an Activity,

Литературные тексты, как и все другие произведения искусства, имеют исторический контекст. ☰ 13 The class android.content.Context provides the connection to the Android system and the resources of the project. It is the interface to global information about the application environment. This class encapsulates context information for an SSL server or client, such as the certificate verification mode and the location of certificates and private key files.. You can understand very well, now, why the name is Context. It’s because it’s just that. The Context provides the link or hook, if you will, for an Activity, Service, or any other component, thereby linking it to the system, enabling access to the global application environment. In other words: the Context provides the answer to the components question of “where the hell am I in relation to app generally and how do I access/communicate with the rest of the app?” If this all seems a bit confusing, a quick look at the methods exposed by the Context class provides some further clues about its true nature. threading.RLock is an example of a reentrant context manager, as are suppress() and redirect_stdout(). Here’s a very simple example of reentrant use:

Note also that being reentrant is not the same thing as being thread safe. redirect_stdout(), for example, is definitely not thread safe, as it makes a global modification to the system state by binding sys.stdout to a different stream. Linguistic context or verbal context refers to the linguistic environment in which a word is used within a text. As a matter of fact, understanding the meaning of vocabulary items using linguistic context may.. with ExitStack() as stack: files = [stack.enter_context(open(fname)) for fname in filenames] # All opened files will automatically be closed at the end of # the with statement, even if attempts to open files later # in the list raise an exception Each instance maintains a stack of registered callbacks that are called in reverse order when the instance is closed (either explicitly or implicitly at the end of a with statement). Note that callbacks are not invoked implicitly when the context stack instance is garbage collected.If a particular application uses this pattern a lot, it can be simplified even further by means of a small helper class: Context is the background, environment, setting, framework, or surroundings of events or occurrences. Simply, context means circumstances forming a background of an event, idea or statement..

The primary use case for ExitStack is the one given in the class documentation: supporting a variable number of context managers and other cleanup operations in a single with statement. The variability may come from the number of context managers needed being driven by user input (such as opening a user specified collection of files), or from some of the context managers being optional: A Context instance is not guaranteed to be synchronized against concurrent access by multiple threads. Threads that need to access a single Context instance concurrently should synchronize.. Since Application, Activity, Service implement the Context interface they can be used where an api call needs a Context parameterAnother example of a reusable, but not reentrant, context manager is ExitStack, as it invokes all currently registered callbacks when leaving any with statement, regardless of where those callbacks were added: Package context defines the Context type, which carries deadlines, cancellation signals, and other request-scoped values across API boundaries and between processes.

Leaving inner context Callback: from inner context Callback: from outer context Leaving outer context As the output from the example shows, reusing a single stack object across multiple with statements works correctly, but attempting to nest them will cause the stack to be cleared at the end of the innermost with statement, which is unlikely to be desirable behaviour.

stack = ExitStack() try: x = stack.enter_context(cm) except Exception: # handle __enter__ exception else: with stack: # Handle normal case Actually needing to do this is likely to indicate that the underlying API should be providing a direct resource management interface for use with try/except/finally statements, but not all APIs are well designed in that regard. When a context manager is the only resource management API provided, then ExitStack can make it easier to handle various situations that can’t be handled directly in a with statement.

Since registered callbacks are invoked in the reverse order of registration, this ends up behaving as if multiple nested with statements had been used with the registered set of callbacks. This even extends to exception handling - if an inner callback suppresses or replaces an exception, then outer callbacks will be passed arguments based on that updated state.Distinct from both single use and reentrant context managers are “reusable” context managers (or, to be completely explicit, “reusable, but not reentrant” context managers, since reentrant context managers are also reusable).

It allows access to application-specific resources and classes, as well as up-calls for application-level operations, such as launching activities, broadcasting and receiving intents, etc. Incoming requests to a server should create a Context, and outgoing calls to servers should accept a Context. The chain of function calls between them must propagate the Context, optionally replacing it with a derived Context created using WithCancel, WithDeadline, WithTimeout, or WithValue. When a Context is canceled, all Contexts derived from it are also canceled. 9 Context is an interface to global information about an application environment.

  2. contextmanager() uses ContextDecorator so the context managers it creates can be used as decorators as well as in with statements. When used as a decorator, a new generator instance is implicitly created on each function call (this allows the otherwise “one-shot” context managers created by contextmanager() to meet the requirement that context managers support multiple invocations in order to be used as decorators).
