Detailed Description

Decoder for dynamic structures defined by a DataDefinition definition.

Member Typedef Documentation

◆ Element

typedef DecoderElement<DecoderElementAccess<const Decoder> > ddl::codec::Decoder::Element

Decoder element.

◆ Elements

typedef ChildElements<DecoderElementAccess<const Decoder> > ddl::codec::Decoder::Elements

Iterator container to iterate all elements of the decoder and get values.

See also: forEachLeafElement, forEachElement, ddl::codec::ChildElements, Decoder::Element

Constructor & Destructor Documentation

◆ Decoder() [1/3]

ddl::codec::Decoder::Decoder ( )

Default constructor.

◆ Decoder() [2/3]

ddl::codec::Decoder::Decoder ( Decoder && )

Move constructor.

◆ Decoder() [3/3]

ddl::codec::Decoder::Decoder ( const Decoder & )

delete

No copy constructor.

Member Function Documentation

◆ getBufferSize() [1/2]

size_t ddl::codec::Decoder::getBufferSize ( ) const

Gets the buffer size in bytes for the main structure.

Return values

size_t of the structure depending on the current representation (getRepresentation)

◆ getBufferSize() [2/2]

size_t ddl::codec::Decoder::getBufferSize ( DataRepresentation representation ) const

Gets the buffer size in bytes for the main structure.

Parameters

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

Returns: The size of the structure in the requested data representation.

◆ getChildElement()

Element ddl::codec::Decoder::getChildElement	(	const CodecIndex &	parent_codec_index,
		std::string_view	relative_path ) const

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

Parameters

[in]	parent_codec_index	The parent codec index.
[in]	relative_path	The child name of the element in point notation (i.e. `"child_element[4].element_value"`).

By using an empty string the deserialized decoding information within CodecIndex will retrieve the same codec index as it is before.

Returns: The child Codec Index of the Decoder.

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

Exceptions

throws std::runtime_error if not found.

◆ getElement() [1/2]

Element ddl::codec::Decoder::getElement ( const CodecIndex & codec_index ) const

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

Parameters

[in] codec_index The codec index.

Returns: The DecoderElement for the given codec index.

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

Exceptions

throws std::runtime_error if not found.

◆ getElement() [2/2]

Element ddl::codec::Decoder::getElement ( std::string_view full_path ) const

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

Parameters

[in] full_path 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 factory exists.

Exceptions

throws std::runtime_error if not found.

◆ getElements()

const Elements & ddl::codec::Decoder::getElements ( ) const

Retrieves the elements of the decoder to get element information and get values.

Returns: Elements The elements iterator container.

See also: forEachLeafElement, forEachElement, Decoder::Element, CodecIndex

◆ isValid()

a_util::result::Result ddl::codec::Decoder::isValid ( ) const

overridevirtual

Returns: Whether or not the decoder is valid.

Return values

ERR_INVALID_ARG The passed data is not large enough.

Reimplemented from ddl::codec::StaticDecoder.

◆ makeCodecFor()

Codec ddl::codec::Decoder::makeCodecFor	(	void *	data,
		size_t	data_size,
		DataRepresentation	representation ) const

Create a new codec with the current dynamic structure layout for a new data buffer.

Parameters

[in]	data	The pointer to the new raw data.
[in]	data_size	The size of the new raw data.
[in]	representation	The representation that the data should be encoded in.

Returns: A codec.

◆ operator=() [1/2]

Decoder & ddl::codec::Decoder::operator= ( const Decoder & )

delete

No copy assignment operator.

◆ operator=() [2/2]

Decoder & ddl::codec::Decoder::operator= ( Decoder && )

Move assignment operator.
