Detailed Description

Semantics for component (tool, service) handles. On access, it will create the
corresponding Configurable instance and store it in the property.

Member Function Documentation

default()

GaudiConfig2.semantics.ComponentHandleSemantics.default	(		self,
			value )

Definition at line 349 of file semantics.py.

    def default(self, value):
        return self.store(value)
 

merge()

GaudiConfig2.semantics.ComponentHandleSemantics.merge	(		self,
			a,
			b )

"Merge" two values.

Used when merging two Configurable instances, by default just ensure
the two values do not conflict, but it can be overridden in
derived semantics to, for example, append to the two lists.

Reimplemented from GaudiConfig2.semantics.PropertySemantics.

        return a.merge(b)
 
 

store()

GaudiConfig2.semantics.ComponentHandleSemantics.store	(		self,
			value )

Validation/transformation of the data to be stored.
