◆ clone()

virtual std::unique_ptr<Attribute> Attribute::clone ( ) const
pure virtualinherited

clone creates and returns and identical (deep) copy of this attribute - i.e.

the result of clone should return true if passed into isMatch.

Referenced by TheWarehouse::update().

◆ clonefunc()

AttribVar::clonefunc ( AttribVar  )

◆ hash()

virtual std::size_t Attribute::hash ( ) const
pure virtualinherited

This function must return a deterministic value that is uniquely determined by the data the attribute holds (i.e.

is initialized with). Ideally, the data should be uniformly and randomly distributed across the domain of size_t values - e.g. 1 and 2 should hash to completely unrelated values. Use of std::hash for POD is encouraged. A convenience hash_combine function is also provided to combine the results an existing hash with one or more other values.

◆ hashfunc()

AttribVar::hashfunc ( _val  )

◆ id()

unsigned int Attribute::id ( ) const
inlineinherited

returns the unique attribute ID associated with all attributes that have the same (mose derived) class as this object.

This ID is determined at construction time this

◆ initFrom()

void AttribVar::initFrom ( const MooseObject obj)
overridevirtual

initFrom reads and stores the desired meta-data from obj for later matching comparisons.

Implements Attribute.

456  auto vi = dynamic_cast<const MooseVariableInterface<Real> *>(obj);

458  _val = static_cast<int>(vi->mooseVariableBase()->number());
459 }

◆ isEqual()

bool AttribVar::isEqual ( const Attribute other) const
overridevirtual

isEqual returns true if the meta-data stored in this attribute is identical to that stored in other.

isEqual does not need to check/compare the values from the instances' id() functions.

Implements Attribute.

◆ isMatch()

bool AttribVar::isMatch ( const Attribute other) const
overridevirtual

isMatch returns true if the meta-data stored in this attribute is equivalent to that stored in other.

This is is for query matching - not exact equivalence. isMatch does not need to check/compare the values from the instances' id() functions.

Implements Attribute.
