Constructor Detail

BufferedEncoder

public BufferedEncoder(int size,
                       com.google.common.base.Function<OutputStream,Encoder> encoderFactory)

Method Detail

reset

public void reset()

writeTo

public void writeTo(OutputStream out)
             throws IOException

Writes all the buffered bytes into the given OutputStream. If the write completed successfully, the internal buffered will be reset.

Parameters:

out - The output stream to write to.

Throws:

IOException

size

public int size()

writeRaw

public Encoder writeRaw(byte[] rawBytes)
                 throws IOException

Writes raw bytes to the buffer without encoding. Same as calling writeRaw(rawBytes, 0, rawBytes.length).

Throws:

IOException

writeRaw

public Encoder writeRaw(byte[] rawBytes,
                        int off,
                        int len)
                 throws IOException

Writes raw bytes to the buffer without encoding.

Parameters:

rawBytes - The bytes to write.

off - Offset to start in the byte array.

len - Number of bytes to write starting from the offset.

Throws:

IOException

writeNull

public Encoder writeNull()
                  throws IOException

Specified by:

writeNull in interface Encoder

Throws:

IOException

Throws:

IOException

writeBytes

public Encoder writeBytes(byte[] bytes)
                   throws IOException

Specified by:

Throws:

IOException

writeBytes

public Encoder writeBytes(byte[] bytes,
                          int off,
                          int len)
                   throws IOException

Specified by:

writeBytes in interface Encoder

Throws:

IOException

writeBytes

public Encoder writeBytes(ByteBuffer bytes)
                   throws IOException

Description copied from interface: Encoder

Writes out the remaining bytes in ByteBuffer.

The given ByteBuffer is untouched after this method returns (i.e. same position and limit).

Specified by:

writeBytes in interface Encoder

Throws:

IOException
