NextBuffer()

Advances the pool to its next buffer. This method should be called once after the constructor to initialize the pool. In contrast to the constructor a Reset() call will advance the pool to its first buffer immediately.

Declaration
public void NextBuffer()

Reset()

Resets the pool to its initial state reusing the first buffer. Calling NextBuffer() is not needed after reset.

Declaration
public void Reset(bool zeroFillBuffers, bool reuseFirst)
Parameters
Type Name Description
System.Boolean zeroFillBuffers

If true the buffers are filled with 0. this should be set to true if this pool is used with Int32BlockPool.SliceWriter.

System.Boolean reuseFirst

If true the first buffer will be reused and calling NextBuffer() is not needed after reset if the block pool was used before ie. NextBuffer() was called before.
