Class Length

java.lang.Object

org.apache.tools.ant.ProjectComponent

org.apache.tools.ant.Task

org.apache.tools.ant.taskdefs.Length

All Implemented Interfaces:

Cloneable, Condition

public class Length
extends Task
implements Condition

Gets lengths: of files/resources, byte size; of strings, length (optionally trimmed). The task is overloaded in this way for semantic reasons, much like Available.

Since:

Ant 1.6.3
