Member Function Documentation

◆ getData() [1/2]

const void* getData

noexcept

Get the current set data.

Remarks: For performance issues this will not check any validity!

Returns: const void* The data pointer

◆ getData() [2/2]

void* getData ( )

noexcept

Get the current set data.

Remarks: For performance issues this will not check any validity!

Returns: void* The data pointer

◆ getElement() [1/5]

Element getElement ( const CodecIndex & codec_index )

Retrieves an element instance based on the codec index of that element.

Parameters

[in] codec_index The codec index.

Returns: The Codec Index of the CodecElement.

Remarks: The element is only valid as long as the static codec exists.

Exceptions

throws std::runtime_error if not found.

◆ getElement() [2/5]

Element getElement

Retrieves an element instance based on the codec index of that element.

Parameters

[in] codec_index The codec index.

Returns: The Codec Index of the DecoderElement.

Remarks: The element is only valid as long as the static decoder exists.

Exceptions

throws std::runtime_error if not found.

◆ getElement() [3/5]

Element getElement ( const std::string & full_element_name )

Retrieves an element instance based on the full name of the element.

Parameters

[in] full_element_name The full name of the element in point notation (i.e. "element1.child_element[4].element_value").

By using an empty string the deserialized decoding information within CodecIndex will retrieve the buffers first address and whole buffersize. By refering an array without dedicated array index position the deserialized decoding information within CodecIndex will be set to the arrays first address and the whole array size. By refering an structured value (not a leaf value) the deserialized decoding information within CodecIndex will be set to the structs first address and the whole struct size.

Returns: The Codec Index of the CodecElement.

Remarks: The element is only valid as long as the static codec exists.

Exceptions

throws std::runtime_error if not found.

◆ getElement() [4/5]

Element getElement

Retrieves an element instance based on the full name of the element.

Parameters

[in] full_element_name The full name of the element in point notation (i.e. "element1.child_element[4].element_value").

By using an empty string the deserialized decoding information within CodecIndex will retrieve the buffers first address and whole buffersize. By refering an array without dedicated array index position the deserialized decoding information within CodecIndex will be set to the arrays first address and the whole array size. By refering an structured value (not a leaf value) the deserialized decoding information within CodecIndex will be set to the structs first address and the whole struct size.

Returns: The Codec Index of the DecoderElement.

Remarks: The element is only valid as long as the static decoder exists.

Exceptions

◆ setElementStringValue()

void setElementStringValue	(	const CodecIndex &	codec_index,
		const std::string &	value

inline

Sets the current value of the given element from given value in type T.

This will cast the given value to the elements data type!

Parameters

[in]	leaf_codec_index	The leaf codec index of the element.
[in]	value	The value to set.

Template Parameters

T	Type of the value to set

Exceptions

std::runtime_error if there is no valid conversion or the given leaf_codec_index is invalid

		const a_util::variant::Variant &	value
	)

Sets the current value of the given element from the given variant.

If this element is a enum type the enum types element name can be used in value. Otherwise the string value is automatically converted to the elments data type, if possible.
