BufferManager Class

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

When implemented in a derived class, you can use the BufferManager class to manage a buffer pool. The pool and its buffers are created when you instantiate this class and destroyed when the buffer pool is reclaimed by garbage collection. Every time you need to use a buffer, you take one from the pool, use it, and return it to the pool when done. This process is much faster and uses fewer resources than creating and destroying a buffer every time you need to use one.

The BufferManager type exposes the following members.


Name Description
BufferManager Initializes a new instance of the BufferManager class.



Name Description
Clear Releases the buffers currently cached in the manager.
CreateBufferManager Creates a new BufferManager with a specified maximum buffer pool size and a maximum size for each individual buffer in the pool.
Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
GetType Gets the Type of the current instance. (Inherited from Object.)
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
ReturnBuffer Returns a buffer to the pool.
TakeBuffer Gets a buffer of at least the specified size from the pool.
ToString Returns a string that represents the current object. (Inherited from Object.)



This class is commonly used while implementing custom encoders or custom transport channels.
