Constructor Detail

DelegatedResourceComparator

public DelegatedResourceComparator()

Method Detail

add

public void add(ResourceComparator c)

Add a delegate ResourceComparator.

Parameters:

c - the next delegate ResourceComparator.

equals

public boolean equals(java.lang.Object o)

Equality method based on the vector of resources, or if a reference, the referredto object.

Specified by:

equals in interface java.util.Comparator

Overrides:

equals in class ResourceComparator

Parameters:

o - the object to check against.

Returns:

true if there is equality.

hashCode

public int hashCode()

Hashcode based on the rules for equality.

Overrides:

hashCode in class ResourceComparator

Returns:

a hashcode.

resourceCompare

protected int resourceCompare(Resource foo,
                              Resource bar)

Compare two Resources.

Specified by:

resourceCompare in class ResourceComparator

Parameters:

foo - the first Resource.

bar - the second Resource.

Returns:

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

dieOnCircularReference

protected void dieOnCircularReference(java.util.Stack stk,
                                      Project p)
                               throws BuildException

Overrides the version from DataType to recurse on nested ResourceSelector s.

Overrides:

dieOnCircularReference in class DataType

Parameters:

stk - the Stack of references.

p - the Project to resolve against.

Throws:

BuildException - on error.
