Detailed Description

The Interface used to retrieve mesh meta data (attributes) set by the MeshGenerator system.

MOOSE objects should avoid retrieving and casting MeshGenerator objects since they are not re-created during a recover operation. This data is read from files early during the simulation setup an d can be used to make decisions about how to setup the rest of the problem.

Constructor & Destructor Documentation

MeshMetaDataInterface() [1/2]

MeshMetaDataInterface::MeshMetaDataInterface ( const MooseObject *  moose_object )

protected

Interface for all objects reading MeshMetaData.

The name of the object gets a bogus prefix, which is not intended to be used for storing data. Instead this value is overridden during retrieval.

Definition at line 14 of file MeshMetaDataInterface.C.

  : _meta_data_app(moose_object->getMooseApp()), _meta_data_object(moose_object)
{
}

MeshMetaDataInterface() [2/2]

MeshMetaDataInterface::MeshMetaDataInterface ( MooseApp &  moose_app )

protected

This class constructor is used for non-Moose-based objects like interfaces.

A name for the storage as well as a system name must be passed in along with the thread ID explicitly.

Definition at line 19 of file MeshMetaDataInterface.C.

  : _meta_data_app(moose_app), _meta_data_object(nullptr)

getMeshProperty() [1/2]

template<typename T >

const T & MeshMetaDataInterface::getMeshProperty ( const std::string &  data_name, const std::string &  prefix  )

This method will throw an error if the property does not exist.
