.get_all_blocks(config, t1, t2, inc) ⇒ Object

(ScheduledResource protocol) Returns a hash where each key is an rid and the value is an array of resource use blocks in the interval t1...t2, ordered by starttime.

What in means depends on inc. If inc(remental) is false, the client is building the interval from scratch. If “hi”, it is an addition to an existing interval on the high side. Similarly for “lo”. This is to avoid re-transmitting blocks that span the current time boundaries on the client.

Here the resource is a channel and the use blocks are programs.

Parameters

  • config - A configuration instance.

  • t1 - Start time.

  • t2 - End time.

  • inc - One of nil, “lo”, “hi” (See above).

Returns

  • Hash - Each key is an rid; value is a list of blocks.
