All Known Subinterfaces:

RandomAccessOutputStream, RevisionDataOutput

All Known Implementing Classes:

ByteBufferOutputStream

public interface DirectDataOutput

Defines an object meant for serializing data (usually an OutputStream) that can write various inputs more efficiently than otherwise (i.e., byte-by-byte copy).

Method Summary

Modifier and Type	Method	Description
void	writeBuffer(BufferView buffer)	Includes the given BufferView.
void	writeInt(int intValue)	Writes the given value as a 32 bit Integer.
void	writeLong(long longValue)	Writes the given value as a 64 bit Long.
void	writeShort(int shortValue)	Writes the given value as a 16 bit Short.

Method Detail

writeBuffer

void writeBuffer(BufferView buffer)
          throws java.io.IOException

Includes the given BufferView.

Parameters:

buffer - The BufferView to include.

Throws:

java.io.IOException - If an IO Exception occurred.

writeShort

void writeShort(int shortValue)
         throws java.io.IOException

Writes the given value as a 16 bit Short. Every effort will be made to write this using efficient techniques (such as making use of intrinsic instructions).

Parameters:

shortValue - The Short value to write.

Throws:

java.io.IOException - If an IO Exception occurred.

writeInt

void writeInt(int intValue)
       throws java.io.IOException

Writes the given value as a 32 bit Integer. Every effort will be made to write this using efficient techniques (such as making use of intrinsic instructions).

Parameters:

intValue - The Integer value to write.

Throws:

java.io.IOException - If an IO Exception occurred.

writeLong

void writeLong(long longValue)
        throws java.io.IOException

Writes the given value as a 64 bit Long. Every effort will be made to write this using efficient techniques (such as making use of intrinsic instructions).

Parameters:

longValue - The Long value to write.

Throws:

java.io.IOException - If an IO Exception occurred.
