Class ContentBuffer

java.lang.Object

com.solacesystems.jcsmp.impl.ContentBuffer

public final class ContentBuffer
extends Object

Fast reusable content buffer. Maintains an internal byte array of DEFAULT_SZ and grows it if necessary to accept bigger contents. The reset() operation resets the ContentBuffer to the DEFAULT_SZ size, if it had grown larger.

                int length)

Read data. Returns number of bytes read, or -1 if there's nothing to read.

Parameters:

destination - Byte array to which content will be copied.

length - Number of bytes to attempt to read.

Returns:

Number of bytes read.

getBufferRefInternal

public byte[] getBufferRefInternal()

Get a reference to the internal backing byte array. Be very careful when using this, it can be larger than the content. Internal Only!

Returns:

result
