dynamic
- if true, reevaluate the property set each time
the set is used. if false cache the property set
the first time and use the cached set on subsequent
occasions.public void setNegate(boolean negate)

- the reference this datatype should point to.

Calling this method as the first line of every bean method of this data type (setXyz, addXyz, createXyz) ensure proper handling of the refid attribute.

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

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