add(ResourceComparator
the ResourceComparator to add.
c)

Add the ResourceComparator to reverse.

Returns:

a negative integer, zero, or a positive integer as the first argument is greater than, equal to, or less than the second.
resourceCompare(Resource
the first Resource.

public Reverse()

Default constructor.

Reverseback to summary
public Reverse(ResourceComparator c)

Construct a new Reverse, supplying the ResourceComparator to be reversed.

Parameters
c:ResourceComparator

the ResourceComparator to reverse.

Method Detail

addback to summary
public void add(ResourceComparator c)

Add the ResourceComparator to reverse.

Parameters
c:ResourceComparator

the ResourceComparator to add.

dieOnCircularReferenceback to summary
protected void dieOnCircularReference(Stack<Object> stk, Project p) throws BuildException

Overrides org.apache.tools.ant.types.DataType.dieOnCircularReference.

Doc from org.apache.tools.ant.types.DataType.dieOnCircularReference.

Check to see whether any DataType we hold references to is included in the Stack (which holds all DataType instances that directly or indirectly reference this instance, including this instance itself).

If one is included, throw a BuildException created by circularReference.

This implementation is appropriate only for a DataType that cannot hold other DataTypes as children.

The general contract of this method is that it shouldn't do anything if checked is true and set it to true on exit.

Parameters
stk:Stack<Object>

the stack of references to check.

p:Project

the project to use to dereference the references.

Exceptions
BuildException:
on error.
resourceCompareback to summary
protected int resourceCompare(Resource foo, Resource bar)

Implements abstract org.apache.tools.ant.types.resources.comparators.ResourceComparator.resourceCompare.

Compare two Resources.

Parameters
foo:Resource

the first Resource.

bar:Resource

the second Resource.

Returns:int

a negative integer, zero, or a positive integer as the first argument is greater than, equal to, or less than the second.
