Interface WritableBuffer

public interface WritableBuffer

An interface for a byte buffer that can only be written to. WritableBuffers are a generic way to transfer bytes to the concrete network transports, like Netty and OkHttp.

Method Summary

Modifier and Type	Method and Description
int	readableBytes() Returns the number of bytes one can read from the buffer.
void	release() Releases the buffer, indicating to the WritableBufferAllocator that this buffer is no longer used and its resources can be reused.
int	writableBytes() Returns the number of bytes one can write to the buffer.
void	write(byte[] src, int srcIndex, int length) Appends length bytes to the buffer from the source array starting at srcIndex.

Method Detail

write

void write(byte[] src,
           int srcIndex,
           int length)

Appends length bytes to the buffer from the source array starting at srcIndex.

Throws:

IndexOutOfBoundsException - if the specified srcIndex is less than 0, if srcIndex + length is greater than src.length, or if length is greater than writableBytes()

writableBytes

int writableBytes()

Returns the number of bytes one can write to the buffer.

readableBytes

int readableBytes()

Returns the number of bytes one can read from the buffer.

release

void release()

Releases the buffer, indicating to the WritableBufferAllocator that this buffer is no longer used and its resources can be reused.
