PHX::DagManager< Traits > | dag_manager_ |
Container that holds all data associated with an evaluation type.
Handles allocation and binding of all field memory.
void PHX::EvaluationContainer< EvalT, Traits >::buildDag | ( | ) |
Build the DAG. This is automatically called by the postRegistrationSetup() method. This function is a power user feature that allows for cases where the user would like to build the dag and query it to use information from the DAG prior to allocating and binding the memory to fields.
const PHX::DagManager< Traits > & PHX::EvaluationContainer< EvalT, Traits >::getDagManager | ( | ) | const |
Returns the underlying DAGManager. Used for queries, debugging and unit testing.
const std::vector< Teuchos::RCP< PHX::FieldTag > > & PHX::EvaluationContainer< EvalT, Traits >::getFieldTags | ( | ) |
Returns the FieldTags for all fields involved in the evaluation. Will return an empty vector unless the user has built the DAG using one of the following calls: postRegistrationSetup(), postRegistrationSetupForType() or buildDagForType().
WARNING: This is a dangerous power user feature. It returns non-const field tags so that the fields can be sized after the DAG has been created.
void PHX::EvaluationContainer< EvalT, Traits >::printEvaluatorStartStopMessage | ( | const Teuchos::RCP< std::ostream > & | ostr | ) |
Print to user specified ostream when each evaluator starts and stops. Useful for debugging. Enabled only in debug builds.
[in] | ostr | RCP to output stream. If set to null, this disables printing. |
void PHX::EvaluationContainer< EvalT, Traits >::setUnmanagedField | ( | const PHX::FieldTag & | f, |
const std::any & | a, | ||
const bool | cleanup_output = true |
||
) |
Set the memory for an unmanaged field.
NOTE: If this method is called after postRegistrationSetup(), the field might be reported as shared when priting even though it is no longer shared (now points to user supplied memory). Output from DAG may be incorrect. Searching the field lists for potential sharing wastes time as this function may be called in the middle of an evaluation, so we will not clean up output or add this to the unmanaged field list unless the user explicitly asks for this cleanup to happen. Execution will always be correct.

Shared fields are fields where their use range in the topological sort of the dag does not overlap. Therefore, the fields can share the same memory allocation tracker. The key is the identifier for the field that will not be allocated since it will use another field's memory. The value is a pair where first is an RCP to the shared field tag, and second is the field string identifier whose memory the shared field will point to.
