Constructor Details

FrameWriterBuffer

public FrameWriterBuffer()

Creates a new WritableBuffer with default capacity.

FrameWriterBuffer

public FrameWriterBuffer(int capacity)

Create a new WritableBuffer with the given capacity.

Parameters:

capacity - the inital capacity to allocate for this buffer.

Method Details

array

public byte[] array()

arrayOffset

public int arrayOffset()

put

public void put(byte b)

Specified by:

put in interface WritableBuffer

putShort

public void putShort(short value)

Specified by:

putShort in interface WritableBuffer

putInt

public void putInt(int value)

Specified by:

putInt in interface WritableBuffer

putLong

public void putLong(long value)

Specified by:

putLong in interface WritableBuffer

putFloat

public void putFloat(float value)

Specified by:

putFloat in interface WritableBuffer

putDouble

public void putDouble(double value)

Specified by:

putDouble in interface WritableBuffer

put

public void put(byte[] src,
 int offset,
 int length)

Specified by:

put in interface WritableBuffer

put

public void put(ByteBuffer payload)

Specified by:

put in interface WritableBuffer

put

public void put(ReadableBuffer payload)

Specified by:

put in interface WritableBuffer

hasRemaining

public boolean hasRemaining()

Specified by:

hasRemaining in interface WritableBuffer

remaining

public int remaining()

Specified by:

remaining in interface WritableBuffer

ensureRemaining

public void ensureRemaining(int requiredRemaining)

Ensures the the buffer has at least the requiredRemaining space specified.

The internal buffer will be doubled if the requested capacity is less than that amount or the buffer will be expanded to the full new requiredRemaining value.

Specified by:

ensureRemaining in interface WritableBuffer

Parameters:

requiredRemaining - the minimum remaining bytes needed to meet the next write operation.

position

public int position()

Specified by:

position in interface WritableBuffer

position

public void position(int position)

Specified by:

position in interface WritableBuffer

limit

public int limit()

Specified by:

limit in interface WritableBuffer

transferTo

public int transferTo(ByteBuffer target)

Copy bytes from this buffer into the target buffer and compacts this buffer.

Copy either all bytes written into this buffer (start to current position) or as many as will fit if the target capacity is less that the bytes written. Bytes not read from this buffer are moved to the front of the buffer and the position is reset to the end of the copied region.

Parameters:

target - The array to move bytes to from those written into this buffer.

Returns:

the number of bytes transfered to the target buffer.
