Detailed Description

template<typename EvalT, typename Traits>
class PHX::AliasField< EvalT, Traits >

Evaluator to help set dependencies for aliased fields.

Member Function Documentation

evaluateFields()

template<typename EvalT , typename Traits >

void PHX::AliasField< EvalT, Traits >::evaluateFields ( typename Traits::EvalData  d )

inlinevirtual

Evaluate all fields that the provider supplies.

Input:

Parameters

d	- user defined data object defined by the EvalData typedef in the traits class.

Implements PHX::EvaluatorWithBaseImpl< Traits >.

postRegistrationSetup()

template<typename EvalT , typename Traits >

void PHX::AliasField< EvalT, Traits >::postRegistrationSetup ( typename Traits::SetupData  d, PHX::FieldManager< Traits > &  vm  )

inlinevirtual

Allows providers to grab pointers to data arrays.

Called once all providers are registered with the manager.

Once the field manager has allocated all data arrays, this method passes the field manager to the providers to allow each provider to grab and store pointers to the field data arrays. Grabbing the data arrays from the variable manager during an actual call to evaluateFields call is too slow due to the map lookup and FieldTag comparison (which uses a string compare). So lookups on field data are only allowed during this setup phase.

Reimplemented from PHX::EvaluatorWithBaseImpl< Traits >.
