Detailed Description

Stream reader showing how to read records containing only metadata information in a DataLayout.

Member Function Documentation

onDataLayoutRead()

bool vrs_sample_apps::MotionStreamPlayer::onDataLayoutRead ( const CurrentRecord &  record, size_t  , DataLayout &    )

inlineoverridevirtual

Callback for DataLayout content blocks, after it was read.

Parameters

record	Metadata associated with the record being read.
blockIndex	Index of the content block being read.
dl	DataLayout read.

Returns

Return true if remaining record content blocks should be read. Return false, if the record should not be read entirely, for instance, if you only need to read some metadata stored in the first content block, but don't need to read & decode the rest of the record.

Reimplemented from vrs::RecordFormatStreamPlayer.
