isFastToString

public boolean isFastToString()

Description copied from interface: Writable

Checks if the writable will be able to be converted toString in an extremely efficient manner. This means without allocating any new buffer space or string copies. Callers should prefer toString over writeTo when ifFastToString returns true.

Note: As of Java 1.7.0_06, String.substring() now copies underlying buffers.

Specified by:

isFastToString in interface Writable

toString

public String toString(int off,
                       int len)

Converts a portion of the input data to a string.

Returns:

the string.

writeTo

public void writeTo(Writer out,
                    long off,
                    long len)
             throws IOException

Writes a portion of the contents of the buffer to another character stream.

Specified by:

writeTo in interface Writable

Throws:

IOException

writeTo

public void writeTo(Encoder encoder,
                    Writer out)
             throws IOException

Description copied from interface: Writable

Writes a streamed version of the object's String representation using the given encoder. What is written must be the same as if encoder.write(this.toString(), out) were called, but may be a much more efficient implementation.

Specified by:

writeTo in interface Writable

Parameters:

encoder - if null, no encoding is performed and will be the same as a call to writeTo(Writer)

Throws:

IOException

writeTo

public void writeTo(Encoder encoder,
                    Writer out,
                    long off,
                    long len)
             throws IOException

Description copied from interface: Writable

Writes a streamed version of the object's String representation using the given encoder. What is written must be the same as if encoder.write(this.toString(), off, len, out) were called, but may be a much more efficient implementation.

Specified by:

writeTo in interface Writable

Parameters:

encoder - if null, no encoding is performed and will be the same as a call to writeTo(Writer,off,len)

Throws:

IOException
