Constructor Detail

WritableByteBuffer

public WritableByteBuffer(int capacity)

Constructs a new byte buffer. It will use a byte array with the specified capacity. The capacity will automatically grow if more space is needed.

Parameters:

capacity - the initial capacity

WritableByteBuffer

public WritableByteBuffer(WritableByteBuffer other)

Constructs a new byte buffer and copies the content from another byte buffer.

Parameters:

other - the other byte buffer

Method Detail

get

public byte get(int index)

Returns the byte at the specified index.

Parameters:

index - the index

Returns:

the byte

size

public int size()

Returns the size of this buffer. This is not the capacity.

Returns:

the size

clear

public void clear()

Removes all bytes from the buffer.

append

public void append(byte b)

Appends the specified byte to the end of the buffer.

Parameters:

b - the byte

append

public void append(byte[] bs,
                   int off,
                   int len)

Appends bytes from the specified byte array to the end of this buffer.

Parameters:

bs - the byte array

off - the index of the first byte to append

len - the number of bytes to append

append

public void append(WritableByteBuffer other,
                   int off,
                   int len)

Appends bytes from the specified byte buffer to the end of this buffer.

Parameters:

other - the byte buffer

off - the index of the first byte to append

len - the number of bytes to append

removeHead

public void removeHead(int n)

Removes the first n bytes from this buffer.

Parameters:

n - the number of bytes to remove

removeFirst

public byte removeFirst()

Removes the first byte from this buffer and returns it.

Returns:

the removed byte

toByteArray

public byte[] toByteArray()

Returns a byte array with the contents of this buffer.

Returns:

the byte array

clone

public Object clone()

Overrides:

clone in class Object
