Constructor & Destructor Documentation

◆ OdRxValue() [1/6]

OdRxValue::OdRxValue	(		)
throw	(	)

inline

Default constructor. Creates an OdRxValue instance.

Definition at line 96 of file RxValue.h.

◆ OdRxValue() [2/6]

◆ OdRxValue() [3/6]

OdRxValue::OdRxValue	(	const OdRxValueType &	type,
		const OdRxValue &	value )
throw	(	)

inline

Constructor for objects of the OdRxValue class. Creates an OdRxValue object with the specified type and value. Source value should be compatible with the target type, e.g. enumeration can be constructed from integer (like reinterpret_cast<> for underlying C++ type).

Parameters

type	[in] Value type of the object to be created.
value	[in] Value to be assigned to the created object.

Definition at line 121 of file RxValue.h.

◆ OdRxValue() [4/6]

template<typename ValueType>

OdRxValue::OdRxValue	(	const ValueType &	value	)

inline

This constructor can be used for blittable (POD) types. For non-blittable types specialization should be declared.

Parameters

value [in] Value type for the constructed value object.

Definition at line 291 of file RxValue.h.

◆ operator>>()

template<typename ValueType>

bool OdRxValue::operator>> ( ValueType & val ) const

inline

Outputs this value to a C++ variable. Unlike rxvalue_cast<>, it takes into account type propagations supported by type().toValueType or OdRxValueType::Desc<ValueType>::value().fromValueType.

Parameters

val	[out] Value type of the corresponding C++ type.

Returns: true if the operation was successful; false otherwise.

Definition at line 451 of file RxValue.h.

◆ serializeIn()
