Restores metadata (field information) about this CRfcComplexParam object from persistent stream.

Returns TRUE when all metadata is successfully restored; FALSE otherwise.

Pers: Reference to a CRfcPersistStream object that encapsulates the persistent data stream.

Important Note: since CRfcComplexParam is intended to be used as a base class from which usable classes are derived, the metadata is best written and read using the derived classes‘ (CRfcStructParam and CRfcTableParam) Write() and Read() functions, respectively.

It is important that the given CRfcPersistStream object actually contains the complete metadata for this CRfcComplexParam object. Incomplete metadata causes the restoration to fail.
