Reverse(ResourceComparator c)
Construct a new Reverse, supplying the ResourceComparator to be reversed. |

add(ResourceComparator c)
Add the ResourceComparator to reverse. |
protected void |
dieOnCircularReference(java.util.Stack<java.lang.Object> stk,

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). |

DataType
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
is true and
set it to true on exit.checked

in class DataType
stk
- the stack of references to check.p
- the project to use to dereference the references.
BuildException
- on error.
