Detailed Description

Special semantics that makes a deep copy of the default value on first access
and considers a property set if its value is different from the default.

This semantics is meant to be used whenever there is no specific semantic
(with proper change detection) implemented for a type.

Member Function Documentation

default()

def GaudiConfig2.semantics.DefaultSemantics.default	(		self,
			value
	)

Definition at line 110 of file semantics.py.

    def default(self, value):
        # remember the default value we got and return a copy
        self._default = value
        self._is_set = False
        return copy.deepcopy(value)
 

is_set()

def GaudiConfig2.semantics.DefaultSemantics.is_set	(		self,
			value
	)

Allow overriding the definition of "is set" if we need helper types.

Reimplemented from GaudiConfig2.semantics.PropertySemantics.

Definition at line 121 of file semantics.py.

    def is_set(self, value):
        try:
            # we assume the property was set if it was changed
            return self._is_set or self._default != value
        except AttributeError:
            # either self._is_set or self._default is not defined,
            # so the value was not explicitly set nor modified
            # from the default
            return False
 
 

store()

def GaudiConfig2.semantics.DefaultSemantics.store	(		self,
			value
	)

Validation/transformation of the data to be stored.

Reimplemented from GaudiConfig2.semantics.PropertySemantics.

Reimplemented in GaudiConfig2.semantics.GaudiHandleArraySemantics.

Definition at line 116 of file semantics.py.

    def store(self, value):
        # flag that the value was explicitly set
        self._is_set = True
        return super(DefaultSemantics, self).store(value)
