Constructor Detail

ArrayBuffer

public ArrayBuffer()

Method Detail

constructor

public void constructor(int length)

The constructor.

Parameters:

length - the size, in bytes, of the array buffer to create.

getByteLength

public int getByteLength()

Returns the size, in bytes, of the array. This is established during construction and cannot be changed.

Returns:

the byte length.

slice

public ArrayBuffer slice(int begin,
                Object end)

Returns a new ArrayBuffer whose contents are a copy of this ArrayBuffer's bytes from begin, inclusive, up to end, exclusive.

Parameters:

begin - byte index to start slicing

end - (optional) byte index to end slicing

Returns:

the newly created ArrayBuffer

setBytes

public void setBytes(int index,
            byte[] array)

Sets the bytes.

Parameters:

index - the starting index

array - the array

getBytes

public byte[] getBytes()

Returns:

the bytes
