# Class DependSelector

java.lang.Object
org.apache.tools.ant.ProjectComponent
org.apache.tools.ant.types.DataType
org.apache.tools.ant.types.selectors.BaseSelector
org.apache.tools.ant.types.selectors.MappingSelector
org.apache.tools.ant.types.selectors.DependSelector

All Implemented Interfaces:
  `Cloneable`, `ResourceSelector`, `FileSelector`

public class DependSelector extends MappingSelector
Selector that filters files based on whether they are newer than a matching file in another directory tree. It can contain a mapper element, so isn't available as an ExtendSelector (since those parameters can't hold other elements).

Since:
  1.5
