Member Function Documentation

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.

clonefunc()

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.

id()

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 AttribSysNum::initFrom ( const MooseObject *  obj )

overridevirtual

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

Implements Attribute.

Definition at line 305 of file Attributes.C.

{
  auto * sys = obj->getParam<SystemBase *>("_sys");
 
  if (sys)
    _val = sys->number();
}

isEqual()

bool AttribSysNum::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.

Definition at line 321 of file Attributes.C.

{
  return isMatch(other);
}

isMatch()

bool AttribSysNum::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.

Definition at line 314 of file Attributes.C.

{
  auto a = dynamic_cast<const AttribSysNum *>(&other);
