Interface class to index the frame formatted trace stream.
This indexer creates an index of trace IDs present in the frame formatted trace stream. It will also index any trigger point markers indicated in the frame format.
Indexing is optional at runtime. Indexes can be saved and re-used.

Default destructor.
The size of block that the indexer will split trace into - this is effectively the index granularity. The indexing will indicate if an indexed element - e.g. a source ID - is present in the block. Smaller granularity will mean a larger index but more resolution in IDs and event positions.
Block sizes will be power of 2 aligned, not less 256 bytes (16 frames). Indexer will choose block size based on total trace size and desired granularity.

The CoreSight frame format can use a reserved ID to indicate trigger or other events programmed into the trace protocol generator. This call indexes these events.
src_idx | : trace index of the event. |
event_type | : type of event. |
|
pure virtual |
Index a set of IDs in a block. Block is assumed to be one of size IndexBlockSize()
May be used by the deformatter to collate IDs and reduce indexing calls. May be used by hardware capture source that has its own index of IDs, to transfer indexing information into the decoder indexer.
src_idx_start | : Index of start of block. |
IDs | : IDs within the block. |
|
pure virtual |
Index a single ID
src_idx | : trace index of source ID |
ID | : The source ID. |

When the frame formatter is using frame syncs (typically TPIU output captured on off chip capture device), this index call notes the position of these elements.
src_idx | : trace index of sync point. |
