Member Function Documentation

GetElement()

tResult GetElement	(	size_t	nIndex,
		const tStructElement *&	pElement
	)		const

Access information about an element.

Parameters

[in]	nIndex	The index of the element.
[out]	pElement	Pointer that will be updated to point to the element information.

Return values

ERR_INVALID_INDEX

Invalid element index.

GetElementAddress()

const void* GetElementAddress

(

size_t

nIndex

)

const

Parameters

[in]

nIndex

The index of the element.

Returns

A pointer to the element or nullptr in case of an error.

GetElementCount()

virtual size_t GetElementCount ( ) const

virtual

Returns

The amount of elements contained in the data structure.

Reimplemented in cDecoder.

GetElementValue() [1/2]

tResult GetElementValue	(	size_t	nIndex,
		A_UTILS_NS::cVariant &	oValue
	)		const

Returns the current value of the given element as a variant.

Parameters

[in]	nIndex	The index of the element.
[out]	oValue	The will be set to the current value.

Return values

ERR_INVALID_INDEX

Invalid element index.

GetElementValue() [2/2]

tResult GetElementValue	(	size_t	nIndex,
		void *	pValue
	)		const

Returns the current value of the given element by copying its data to the passed-in location.

Parameters

[in]	nIndex	The index of the element.
[out]	pValue	The location where the value should be copied to.

Return values

ERR_INVALID_INDEX

Invalid element index.

GetElementValueString()

A_UTILS_NS::cString GetElementValueString

(

size_t

nIndex

)

const

Returns the current value of the given element as a string.

Parameters

(

tDataRepresentation

eRep = tDataRepresentation::Deserialized

)

const

Parameters

[in]

eRep

The data representation for which the buffer size should be returned.

Returns

The size of the structure in the requested data representation.

GetStructElementName()

static const char* GetStructElementName ( const tStructElement *  pElement )

static

Access information about an element.

Parameters

[in]

pElement

pointer to the element to retriev the name from

Return values
