Method Detail

constructor

public void constructor(Object object,
                        Object byteOffset,
                        Object length)

The constructor.

Parameters:

object - the object

byteOffset - optional byteOffset

length - optional length

getLength

public int getLength()

Sets multiple values in the typed array, reading input values from a specified array.

Parameters:

sourceArray - the source array

offset - the offset into the target array at which to begin writing values from the source one
