Constructor Detail

FastOutput

public FastOutput()

Creates an uninitialized Output. Output.setBuffer(byte[], int) must be called before the Output is used.

FastOutput

public FastOutput(int bufferSize)

Creates a new Output for writing to a byte array.

Parameters:

bufferSize - The initial and maximum size of the buffer. An exception is thrown if this size is exceeded.

FastOutput

public FastOutput(int bufferSize,
          int maxBufferSize)

Creates a new Output for writing to a byte array.

Parameters:

bufferSize - The initial size of the buffer.

maxBufferSize - The buffer is doubled as needed until it exceeds maxBufferSize and an exception is thrown.

FastOutput

public FastOutput(byte[] buffer)

Creates a new Output for writing to a byte array.

See Also:

Output.setBuffer(byte[])

FastOutput

public FastOutput(byte[] buffer,
          int maxBufferSize)

Creates a new Output for writing to a byte array.

See Also:

Output.setBuffer(byte[], int)

FastOutput

public FastOutput(OutputStream outputStream)

Creates a new Output for writing to an OutputStream. A buffer size of 4096 is used.

FastOutput

public FastOutput(OutputStream outputStream,
          int bufferSize)

Creates a new Output for writing to an OutputStream.

Method Detail

writeInt

public int writeInt(int value,
           boolean optimizePositive)
             throws KryoException

Description copied from class: Output

Writes a 1-5 byte int. This stream may consider such a variable length encoding request as a hint. It is not guaranteed that a variable length encoding will be really used. The stream may decide to use native-sized integer representation for efficiency reasons.

Overrides:

writeInt in class Output

optimizePositive - If true, small positive numbers will be more efficient (1 byte) and small negative numbers will be inefficient (5 bytes).

Throws:

KryoException

writeLong

public int writeLong(long value,
            boolean optimizePositive)
              throws KryoException

Description copied from class: Output

Writes a 1-9 byte long. This stream may consider such a variable length encoding request as a hint. It is not guaranteed that a variable length encoding will be really used. The stream may decide to use native-sized integer representation for efficiency reasons.

Overrides:

writeLong in class Output

optimizePositive - If true, small positive numbers will be more efficient (1 byte) and small negative numbers will be inefficient (9 bytes).

Throws:

KryoException
