Constructor Detail

ByteBuffer

public ByteBuffer(int initialCapacity,
          int capacityIncrement)

Constructs an empty ByteBuffer with the specified initial capacity and capacity increment.

Parameters:

initialCapacity - the initial capacity of the ByteBuffer.

capacityIncrement - the amount by which the capacity is increased when the ByteBuffer overflows.

Throws:

IllegalArgumentException - if the specified initial capacity is negative

ByteBuffer

public ByteBuffer(int initialCapacity)

Constructs an empty ByteBuffer with the specified initial capacity and with its capacity increment equal to zero.

Parameters:

initialCapacity - the initial capacity of the ByteBuffer.

Throws:

IllegalArgumentException - if the specified initial capacity is negative

ByteBuffer

public ByteBuffer()

Constructs an empty ByteBuffer so that its internal data array has size 10 and its standard capacity increment is zero.

Method Detail

trimToSize

public void trimToSize()

Trims the capacity of this ByteBuffer to be the ByteBuffer's current size. If the capacity of this cector is larger than its current size, then the capacity is changed to equal the size by replacing its internal data array, kept in the field elementData, with a smaller one. An application can use this operation to minimize the storage of a ByteBuffer.

capacity

public int capacity()

Returns the current capacity of this ByteBuffer.

Returns:

the current capacity (the length of its internal data arary, kept in the field elementData of this ByteBuffer.

size

public int size()

Returns the number of components in this ByteBuffer.

Returns:

the number of components in this ByteBuffer.

isEmpty

public boolean isEmpty()

Tests if this ByteBuffer has no components.

Returns:

true if and only if this ByteBuffer has no components, that is, its size is zero; false otherwise.

append

public void append(byte value)

append

public void append(int value)

append

public void append(String value)

toArray

public byte[] toArray()

Returns an array containing all of the elements in this ByteBuffer in the correct order.
