flash.sampler 

The flash.sampler package contains methods and classes for tracking procedure calls so that you can profile memory usage and optimize applications. This package is used by the profiling agent distributed with Adobe Flash Builder, and is provided for your use for customizing the profiling agent or building your own memory tests. After you know where an application uses the most memory, you can focus your optimization effort and speed up the application's performance. The classes and methods in this package require the Flash Player debugger version 9.0.115.0 or later. For more information, see the flash.sampler methods overview.



Functions
 FunctionDescription
 clearSamples Clears the current set of Sample objects.
 getGetterInvocationCount Returns the number of times a get function was executed.
 getInvocationCount Returns the number of times a method was executed.
 getLexicalScopes Exposes the lexical scope of a Function so that captured scope objects (including activation objects and with scopes) are seen by the profiler as being retained by the Function instance.
 getMasterString Returns the master string upon which this string depends, or null if this string does not depend on another string.
 getMemberNames Returns an object containing all members of a specified object, including private members.
 getSampleCount Returns the number of samples collected.
 getSamples Returns an object of memory usage Sample instances from the last sampling session.
 getSavedThis Returns the saved "this" from a Method closure that you normal can't see from AS.
 getSetterInvocationCount Returns the number of times a set function was executed.
 getSize Returns the size in memory of a specified object when used with the Flash Player 9.0.115.0 or later debugger version.
 isGetterSetter Checks to see if a property is defined by a get/set function.
 pauseSampling Stops the sampling process momentarily.
 sampleInternalAllocs Tells the sampler if it should create NewObjectSamples for internal allocations from the flash player.
 setSamplerCallback Sets a callback function for the sampler - this function will be called when the sample stream is almost exhausted.
 startSampling Begins the process of collecting memory usage Sample objects.
 stopSampling Ends the process of collecting memory usage Sample objects and frees resources dedicated to the sampling process.
Classes
 ClassDescription
 DeleteObjectSample The DeleteObjectSample class represents objects that are created within a getSamples() stream; each DeleteObjectSample object corresponds to a NewObjectSample object.
 NewObjectSample The NewObjectSample class represents objects that are created within a getSamples() stream.
 Sample The Sample class creates objects that hold memory analysis information over distinct durations.
 StackFrame The StackFrame class provides access to the properties of a data block containing a function.
