Constructor Detail

Writer

public Writer()

Creates a new writer.

Writer

public Writer(int initialCapacity)

Creates a new writer.

Parameters:

initialCapacity - initial byte capacity

Method Detail

add

public void add(byte[] bytes,
                int off,
                int length)

Adds bytes to this writer's buffer.

Parameters:

bytes - byte array

off - offset into array to start copying bytes

length - number of bytes to add

Throws:

IndexOutOfBoundsException - if off or length are invalid

add

public void add(boolean b)

Adds a Boolean value to this writer's buffer.

Parameters:

b - Boolean value

toArray

public byte[] toArray()

Gets (a copy of) the contents of this writer's buffer.

Returns:

byte buffer contents

toByteBuffer

public ByteBuffer toByteBuffer()

Gets a ByteBuffer wrapped around this writer's buffer.

Returns:

byte buffer

writeVInt

public void writeVInt(int i)

Adds an integer value to this writer's buffer. The integer is encoded as a variable-length list of bytes. See writeVLong(long) for a description of the encoding.

Parameters:

i - integer value

writeVLong

public void writeVLong(long i)

Adds a long value to this writer's buffer. The long is encoded as a variable-length list of bytes. For a description of the encoding scheme, see WritableUtils.writeVLong() in the Hadoop API. [link]

Parameters:

i - long value

size

public int size()
