Public functions

OnSetDataEvent

virtual void OnSetDataEvent(
  SetDataEventType aType,
  PropertyPathHandle aHandle
)=0

Signals to delegates when notable events occur while parsing dictionaries.

In all cases, a property path handle is provided that provides more context on what this event applies to.

For dictionary replace begin/ends, these handles are purely schema handles. For dictionary item added/modififed events, these handles are property path handles as they contain the dictionary key as well.

SetData

virtual WEAVE_ERROR SetData(
  PropertyPathHandle aHandle,
  nl::Weave::TLV::TLVReader & aReader,
  bool aIsNull
)=0

Given a path handle to a node, a TLV reader, and an indication of whether a null type was received, set the data in the callee.

TDM will only call this function for handles that are nullable, optional, ephemeral, or leafs. If aHandle is a non-leaf node and is nullified, TDM will not call SetData for its children.

Details

Parameters

`[in] aHandle`	The PropertyPathHandle in question.
`[in,out] aReader`	The TLV reader to read from.
`[out] aIsNull`	Is aHandle nullified?

Return Values

`WEAVE_NO_ERROR`	On success.
`other`	Was unable to read out data from the reader.

SetLeafData

virtual WEAVE_ERROR SetLeafData(
  PropertyPathHandle aLeafHandle,
  nl::Weave::TLV::TLVReader & aReader
)=0

Given a path handle to a leaf node and a TLV reader, set the leaf data in the callee.

Details

Return Values

`WEAVE_NO_ERROR`	On success.
`other`	Was unable to read out data from the reader.
