	Adds a listener to the notifier. Parameters: listener - a listener that reacts on events

addRegion
public void addRegion(R region)(Code)
	Add the supplied DocumentRegion to the manager. Parameters: region - the DocumentRegion to be inserted into the manager

changeRegion
public void changeRegion(R region, Lambda<Object, R> cmd)(Code)
	Apply the given command to the specified region to change it. Parameters: region - the region to find and change Parameters: cmd - command that mutates the region.

clearRegions
public void clearRegions()(Code)
	Tells the manager to remove all regions.

getCurrentRegion
public R getCurrentRegion()(Code)
	the current region or null if none selected

getCurrentRegionIndex
public int getCurrentRegionIndex()(Code)
	the index of the current region or -1 if none selected

getMaximumSize
public int getMaximumSize()(Code)
	the maximum number of regions that can be stored in this manager.

getRegionAt
public R getRegionAt(OpenDefinitionsDocument odd, int offset)(Code)
	Returns the region in this manager at the given offset, or null if one does not exist. Parameters: odd - the document Parameters: offset - the offset in the document the DocumentRegion at the given line number, or null if it does not exist.

getRegionOverlapping
