newArray

public void newArray(int size)

Description copied from class: DataBuffer

Allocates a new, empty array of the given size and assign it to the arrayObject property. It is assumed that subclasses will also set it to a variable of the correct class (e.g. char[]) for ease of access as well. Copying of existing contents is managed by this superclass.
