Members

eventEmitter{vcs.vcm.interaction.EventEmitter}

featureInteraction{vcs.vcm.interaction.FeatureAtPixelInteraction}

interactions{Array.<vcs.vcm.interaction.AbstractInteraction>}

A copy of all the EventHandler interactions

positionInteraction{vcs.vcm.interaction.CoordinateAtPixel}

Methods

vcs.vcm.interaction.EventHandler.getInstance(){vcs.vcm.interaction.EventHandler}

addExclusiveInteraction(interaction, removed, index, id){function}

Add a dynamic interaction to the interaction chain. This is the default methodology for user map interactions, such as drawing or measuring. If another exclusive interaction is added, this interaction is removed and a provided callback is called. Use the id parameter to add multiple interactions from the same source (if you don't wish to provide an vcs.vcm.interaction.InteractionChain

Name	Type	Default	Description
interaction	vcs.vcm.interaction.AbstractInteraction
removed	function		the callback for when the interaction is forcefully removed.
index	number	2	the position at which to push the interaction
id	string		an id to allow for multiple interactions to belong to the same exclusive registerer

Returns:

function to remove the interaction with. returns number of removed interactions (0|1)

addPersistentInteraction(interaction, index){function}

Adds an interaction permanently to the interaction chain. Only add non-interferring interactions in such a fashion (for instance for displaying the cursor position)

Name	Type	Default	Description
interaction	vcs.vcm.interaction.AbstractInteraction
index	number	2	at what position this interaction should be added. By default, it is added after the featureInteraction

Returns:

function to remove the interaction with. returns number of removed interactions (0|1)
