Member Function Documentation

getElement()

a_util::result::Result getElement	(	size_t	index,
		const StructElement *&	element
	)		const

Access information about an element.

Parameters

[in]	index	The index of the element.
[out]	element	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

index

)

const

Parameters

[in]

index

The index of the element.

Returns

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

getElementCount()

virtual size_t getElementCount ( ) const

virtual

Returns

The amount of elements contained in the data structure.

Reimplemented in Decoder.

getElementValue() [1/2]

a_util::result::Result getElementValue	(	size_t	index,
		a_util::variant::Variant &	value
	)		const

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

Parameters

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

Return values

ERR_INVALID_INDEX

Invalid element index.

getElementValue() [2/2]

a_util::result::Result getElementValue	(	size_t	index,
		void *	value
	)		const

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

Parameters

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

Return values

ERR_INVALID_INDEX

Invalid element index.

getRepresentation()

DataRepresentation getRepresentation

(

)

const

Returns

The data representation which this decoder handles.

getStaticBufferSize()

size_t getStaticBufferSize

(

DataRepresentation

rep = deserialized

)

const

Parameters

[in]

rep

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

Returns

The size of the structure in the requested data representation.

isValid()

virtual a_util::result::Result isValid ( ) const

virtual

Returns

Whether or not the decoder is valid.

Return values

ERR_INVALID_ARG

The passed data is not large enough.

Reimplemented in Decoder.
