Function Documentation

dt_writer* dt_create_validator_writer (  dt_writer *  delegate  )

Creates a writer that verifies the validity of the dt_step sequence it receives. This writer can be used as a filter, which verifies that an input source (such as a file parser) provides a valid data structure. Parameters: delegate  Optional pointer to an existing dt_writer instance to which each dt_step that has successfully been validated will be forwarded. Definition at line 27 of file dt_stream_validator.c.

dt_bool dt_validator_writer_completed (  dt_writer *  validator  )

Checks whether validator has received a dt_end step. Because a datatree transmission may be truncated even though it does not contain an error, this function can be called to verify that the transmission was complete and successful. Returns: A non-zero value if the transmission was complete and a dt_end step was received. zero if the object has not received a complete transmission (or it is not a validator_writer).
