Detailed Description

Helper class for the burst_creator node.

Checks for overlapping bursts from each channel. If there are overlapping bursts, they will be merged so duplicates are eliminated.

burst_calc::burst BurstMerger::merge	(	const burst_calc::burst &	b1,
		const burst_calc::burst &	b2
	)		[private]

Merges two bursts into a single burst.

Pre-condition: the time span of the bursts must overlap in some way.

Parameters:

b1	one of the bursts to be merged
b2	the other burst to be merged

Returns:

the merged burst

void BurstMerger::update

(

)

Performs the merge operation after new bursts have been added.

First, check all stored bursts and merge any that can be. Then compare all stored bursts against the times to determine if any of them can be published.

Definition at line 37 of file burst_merger.cpp.

void BurstMerger::updateTime	(	int	index,
		const ros::Time *	t
	)

Updates the burst checker time pointer for a channel.

The pointer either points to the start time of that channel's possible burst, or is null if there is no possible burst.

Parameters:

index	the index of the channel
t	the time pointer of the channel's burst checker
