Constructor Detail

FastInput

public FastInput()

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

FastInput

public FastInput(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.

FastInput

public FastInput(byte[] buffer)

Creates a new Output for writing to a byte array.

See Also:

Input.setBuffer(byte[])

FastInput

public FastInput(byte[] buffer,
                 int offset,
                 int count)

Creates a new Output for writing to a byte array.

See Also:

Input.setBuffer(byte[], int, int)

FastInput

public FastInput(InputStream outputStream)

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

FastInput

public FastInput(InputStream outputStream,
                 int bufferSize)

Creates a new Output for writing to an OutputStream.

Method Detail

readInt

public int readInt(boolean optimizePositive)
            throws KryoException

Description copied from class: Input

Reads 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:

readInt in class Input

Throws:

KryoException

readLong

public long readLong(boolean optimizePositive)
              throws KryoException

Description copied from class: Input

Reads 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:

readLong in class Input

Throws:

KryoException
