Constructor Detail

DecoderInputBuffer

public DecoderInputBuffer(int bufferReplacementMode)

Parameters:

bufferReplacementMode - Determines the behavior of ensureSpaceForWrite(int). One of BUFFER_REPLACEMENT_MODE_DISABLED, BUFFER_REPLACEMENT_MODE_NORMAL and BUFFER_REPLACEMENT_MODE_DIRECT.

Method Detail

ensureSpaceForWrite

public void ensureSpaceForWrite(int length)
                         throws java.lang.IllegalStateException

Ensures that data is large enough to accommodate a write of a given length at its current position.

If the capacity of data is sufficient this method does nothing. If the capacity is insufficient then an attempt is made to replace data with a new ByteBuffer whose capacity is sufficient. Data up to the current position is copied to the new buffer.

Parameters:

length - The length of the write that must be accommodated, in bytes.

Throws:

java.lang.IllegalStateException - If there is insufficient capacity to accommodate the write and the buffer replacement mode of the holder is BUFFER_REPLACEMENT_MODE_DISABLED.

isEncrypted

public final boolean isEncrypted()

Returns whether the C.BUFFER_FLAG_ENCRYPTED flag is set.

flip

public final void flip()

Flips data in preparation for being queued to a decoder.

See Also:

Buffer.flip()

clear

public void clear()

Description copied from class: Buffer

Clears the buffer.

Overrides:

clear in class Buffer
