Method Detail
-
add
public void add(ResourceComparator c)
Add a ResourceComparator to this Compare selector. If multiple ResourceComparators are added, they will be processed in LIFO order.- Parameters:
c- the ResourceComparator to add.
-
setAgainst
public void setAgainst(Quantifier against)
Set the quantifier to be used. Default "all".- Parameters:
against- the Quantifier EnumeratedAttribute to use.
-
setWhen
public void setWhen(Comparison when)
Set the comparison to be used. Default "equal".- Parameters:
when- the Comparison EnumeratedAttribute to use.
-
createControl
public ResourceCollection createControl()
Create the nested control element. These are the resources to compare against.- Returns:
- ResourceCollection.
-
isSelected
public boolean isSelected(Resource r)
Return true if this Resource is selected.- Specified by:
isSelectedin interfaceResourceSelector- Parameters:
r- the Resource to check.- Returns:
- whether the Resource was selected.
-
dieOnCircularReference
protected void dieOnCircularReference(java.util.Stack<java.lang.Object> stk, Project p) throws BuildExceptionOverrides the version from DataType to recurse on nested ResourceComparators.- Overrides:
dieOnCircularReferencein classDataType- Parameters:
stk- the stack of data types to use (recursively).p- the project to use to dereference the references.- Throws:
BuildException- on error.
