Method Details

pour

public static int pour(ByteBuffer source,
 ByteBuffer destination)

Returns:

number of bytes poured

pourArrayToBuffer

public static int pourArrayToBuffer(byte[] source,
 int offset,
 int sizeRequested,
 ByteBuffer destination)

Assumes destination is ready to be written.

Returns:

number of bytes poured which may be fewer than sizeRequested if destination has insufficient remaining

pourAll

public static int pourAll(ByteBuffer source,
 TransportInput destinationTransportInput)
                   throws TransportException

Pours the contents of source into destinationTransportInput, calling the TransportInput many times if necessary. If the TransportInput returns a TransportResult other than ok, data may remain in source.

Throws:

TransportException

pourBufferToArray

public static int pourBufferToArray(ByteBuffer source,
 byte[] destination,
 int offset,
 int sizeRequested)

Assumes source is ready to be read.

Returns:

number of bytes poured which may be fewer than sizeRequested if source has insufficient remaining

newWriteableBuffer

public static ByteBuffer newWriteableBuffer(int capacity)

newReadableBuffer

public static ByteBuffer newReadableBuffer(int capacity)
