Class XArray

java.lang.Object
  org.geotools.resources.XArray

public final class XArray
extends java.lang.Object

Simple operations on arrays. This class provides a central place for inserting and deleting elements in an array, as well as resizing the array. This class may be removed if JavaSoft provide some language construct functionally equivalent to C/C++'s realloc.

Method Detail

doResize

private static java.lang.Object doResize(java.lang.Object array,
                                         int length)

Returns a new table which contains the same elements as array but with the length specified. If the desired length is longer than the initial length of the array table, the returned table will contain all the elements of array as well as the elements initialised to null at the end of the table. If, on the contrary, the desired length is shorter than the initial length of the array table, the table will be truncated (that is to say the surplus array elements will be forgotten). If the length of array is equal to length, then array will be returned as it stands.
