class ValueBuilder¶

Incrementally define and initialize a PVStructure

Equivalent to FieldBuilder with the added ability to assign initial values.

epics::pvData::PVStructurePtr val(epics::pvData::ValueBuilder()
                                  .add<pvInt>("intfld", 42)
                                  .addNested("sub")
                                   .add<pvString>("strfld", "testing")
                                  .endNested()
                                  .buildPVStructure());

Public Functions

explicit ValueBuilder(const std::string &id = std::string())¶: empty structure

explicit ValueBuilder(const PVStructure&)¶: Clone existing definition and value.

~ValueBuilder()¶

template<ScalarType ENUM> inline FORCE_INLINE ValueBuilder & add (const std::string &name, typename meta::arg_type< typename ScalarTypeTraits< ENUM >::type >::type V): Add a scalar field with a given name and initial value.

template<class T> inline FORCE_INLINE ValueBuilder & add (const std::string &name, const shared_vector< const T > &V): Add a scalar array field.

inline FORCE_INLINE ValueBuilder & add (const std::string &name, const PVStructure &V)

ValueBuilder &addNested(const std::string &name, Type type = structure, const std::string &id = std::string())¶: Start a sub-structure.

ValueBuilder &endNested()¶: End a sub-structure.

std::tr1::shared_ptr<PVStructure> buildPVStructure() const¶: Complete building structure

Note

ValueBuilder may be re-used after calling buildPVStructure()
