Detailed Description

Codec for dynamic structures defined by a DDL definition.

Currently the amount of dynamic elements is determined during construction only (by the current values in the structure).

Member Function Documentation

◆ GetElementAddress() [1/2]

void* GetElementAddress ( size_t nIndex )

Parameters

[in] nIndex The index of the element.

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

◆ GetElementAddress() [2/2]

const void* GetElementAddress

Parameters

[in] nIndex The index of the element.

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

◆ SetConstants()

tResult SetConstants ( )

Sets all elements to their constant values defined in the DDL.

Returns: Standard result.

◆ SetElementValue() [1/2]

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

Sets the current value of the given element to the given value.

Parameters

[in]	nIndex	The index of the element.
[in]	oValue	The value.

Return values

ERR_INVALID_INDEX Invalid element index.

◆ SetElementValue() [2/2]

tResult SetElementValue	(	size_t	nIndex,
		const void *	pValue
	)

Sets the current value of the given element by copying its data from the passed-in location.

Parameters

[in]	nIndex	The index of the element.
[in]	pValue	The location where the data should be copied from.

Return values

ERR_INVALID_INDEX Invalid element index.
