A helper function to find the location of the nullified fields array located at the end of the C struct.

The nullified_fields member of the C struct is expected to be located directly after the last member described by the array of FieldDescriptors. It is not in the list of field descriptors, as it's meant to be a hidden utility for creators and consumers of nullable events. This struct member does not exist for events with no nullable fields, however by construction of setters and getters, no out of bounds accesses should occur.

Details
Parameters
[in] aStructureData
A pointer to the c-struct.
[in] aSchemaDescriptor
SchemaFieldDescriptors to describe the c struct.
[out] aNullifiedFields
A pointer to nullified_fields member of the c struct.
Return Values
WEAVE_NO_ERROR

[in] aReader
The reader to use for reading in the data
[in] aStructureData
A pointer to the destination c-structure data into which we'll read based on the SchemaFieldDescriptor
[in] aFieldDescriptors
SchemaFieldDescriptors to describe the c struct + TLV
[in] aContext
Serialization context containing any state required for the operation.
Return Values
WEAVE_NO_ERROR
On success.
other
Other errors that may be returned from the aReader.

TLVReaderToDeserializedDataHelper

WEAVE_ERROR TLVReaderToDeserializedDataHelper(
  nl::Weave::TLV::TLVReader & aReader,
  uint8_t aDataTag,
  void *aAppData,
  SerializationContext *aContext
)

A helper function that deserializes a single TLV data element.

The function splits StructureSchemaPointerPair into structure data and descriptors to pass through to ReadDataForType.

Details
Parameters
[in] aReader
The reader containing data to be deserialized
[in] aDataTag
Unused for the moment
[in] aAppData
StructureSchemaPointerPair that contains a pointer to structure data and field descriptors. void* due to prototype
[in] aContext
Serialization context containing any state required for the operation.
Return Values
WEAVE_NO_ERROR
On success.
other
Other errors that mey be returned from the aReader.

WriteArrayData

WEAVE_ERROR WriteArrayData(
  TLVWriter & aWriter,
  void *aStructureData,
  const FieldDescriptor *aFieldPtr
)

A writer function that writes an array structure.

Details
Parameters
[in] aWriter
The writer to use for writing out the structure
[in] aStructureData
A pointer to the c-structure data to write based on the FieldDescriptor
[in] aFieldPtr
FieldDescriptor to describe the array c struct + TLV
Return Values
WEAVE_NO_ERROR
On success.
other
Other errors that mey be returned from the aWriter.

WriteDataForType

WEAVE_ERROR WriteDataForType(
  TLVWriter & aWriter,
  void *aStructureData,
  const FieldDescriptor *& aFieldPtr,
  SerializedFieldType aType,
  bool aInArray
)

A writer function write a specific entry into the TLV based on structure data.

Details
Parameters
[in] aWriter
The writer to use for writing out the structure
[in] aStructureData
A pointer to the c-structure data to write
[in,out] aFieldPtr
FieldDescriptor to describe the fields and TLV tag. The function will increment the pointer s.t. it will point to the next element in the FieldDescritor array
[in] aType
The SerializedFieldType of the field
[in] aInArray
True if we're writing an array (use anonymous tag)
Return Values
WEAVE_NO_ERROR
On success.
other
Other errors that mey be returned from the aWriter.

WriteNullableDataForType

WEAVE_ERROR WriteNullableDataForType(
  TLVWriter & aWriter,
  void *aStructureData,
  const FieldDescriptor *& aFieldPtr,
  SerializedFieldType aType,
  bool aIsNullified
)

A writer function to check whether data is nullable/nullified before writing to the TLV.

Details
Parameters
[in] aWriter
The writer to use for writing out the structure
[in] aStructureData
A pointer to the c-structure data to read
[in,out] aFieldPtr
FieldDescriptor to describe the fields and TLV tag. The function will increment the pointer s.t. it will point to the next element in the FieldDescriptor array
[in] aType
The SerializedFieldType of the field
[in] aIsNullified
The TLV tag will be nullified if this is true.
Return Values
WEAVE_NO_ERROR
On success.
other
TLV errors while writing.
