Class Documentation

class PVDataCreate

This is a singleton class for creating data instances.

Public Functions

PVFieldPtr createPVField(FieldConstPtr const &field)

Create a PVField using given Field introspection data.

Parameters

field – The introspection data to be used to create PVField.

Returns

The PVField implementation.

PVFieldPtr createPVField(PVFieldPtr const &fieldToClone)

Create a PVField using given a PVField to clone. This method calls the appropriate createPVScalar, createPVArray, or createPVStructure.

Parameters

fieldToClone – The field to clone.

Returns

The PVField implementation

PVScalarPtr createPVScalar(ScalarConstPtr const &scalar)

Create an implementation of a scalar field reusing the Scalar introspection interface.

Parameters

scalar – The introspection interface.

Returns

The PVScalar implementation.

PVScalarPtr createPVScalar(ScalarType scalarType)

Create an implementation of a scalar field. A Scalar introspection interface is created.

Parameters

scalarType – The scalar type.

Returns

The PVScalar implementation.

PVScalarPtr createPVScalar(PVScalarPtr const &scalarToClone)

Create an implementation of a scalar field by cloning an existing PVScalar. The new PVScalar will have the same value and auxInfo as the original.

Parameters

scalarToClone – The PVScalar to clone.

Returns

The PVScalar implementation.

PVStructurePtr createPVStructure(StringArray const &fieldNames, PVFieldPtrArray const &pvFields)

Create implementation for PVStructure.

Parameters

  • fieldNames – The field names.

  • pvFields – Array of PVFields

Returns

The PVStructure implementation

PVStructurePtr createPVStructure(PVStructurePtr const &structToClone)

Create implementation for PVStructure.

Parameters

structToClone – A structure. Each subfield and any auxInfo is cloned and added to the newly created structure.

Returns

The PVStructure implementation.

PVUnionPtr createPVUnion(UnionConstPtr const &punion)

Create implementation for PVUnion.

Parameters

punion – The introspection interface.

Returns

The PVUnion implementation

PVUnionPtr createPVUnion(PVUnionPtr const &unionToClone)

Create implementation for PVUnion.

Parameters

unionToClone – A union. Each subfield is cloned and added to the newly created union.

Returns

The PVUnion implementation.

PVUnionPtr createPVVariantUnion()

Create variant union implementation.

Returns

The variant PVUnion implementation.

PVScalarArrayPtr createPVScalarArray(ScalarArrayConstPtr const &scalarArray)

Create an implementation of an array field reusing the Array introspection interface.

Parameters

scalarArray – The introspection interface.

Returns

The PVScalarArray implementation.

PVScalarArrayPtr createPVScalarArray(ScalarType elementType)

Create an implementation for an array field. An Array introspection interface is created.

Parameters

elementType – The element type.

Returns

The PVScalarArray implementation.

PVScalarArrayPtr createPVScalarArray(PVScalarArrayPtr const &scalarArrayToClone)

Create an implementation of an array field by cloning an existing PVArray. The new PVArray will have the same value and auxInfo as the original.

Parameters

scalarArrayToClone – The PVScalarArray to clone.

Returns

The PVScalarArray implementation.

template<typename PVAT>
inline std::tr1::shared_ptr<PVAT> createPVScalarArray()

template version

Parameters

structureArray – The introspection interface. All elements share the same introspection interface.

Returns

The PVStructureArray implementation.

inline PVStructureArrayPtr createPVStructureArray(StructureConstPtr const &structure)

Create an implementation of an array with structure elements.

Parameters

structure – The introspection interface that is used to create StructureArrayConstPtr. All elements share the same introspection interface.
