Module Extension

Returns all registered extension ids.

example

// Could returns [ "Document", "MyCustomExtension" ]
JMap.Extension.getAllRegisteredIds()

Returns true if any of the currently registered extension has defined a "renderMouseOver" method.

example

const hasMouseOver = JMap.Extension.hasMouseOver()
if (hasMouseOver) {
   console.log("some extensions have defined mouseOvers")
} else {
   console.log("there is currently no extension defining mouseOvers")
}

Tell if an extension has been registered or not.

It can be useful to know if a JMap extension is in use or not.

throws

Error if extensionId format is not correct

example

// returns true if the JMap Document extension is in use or not
JMap.Extension.isRegistered("Document")

Register your own extension.

throws

Error if a parameter is not correct

example

JMap.Extension.register({
 id: "MyExtension", // Unique id
 initFn: () => {
   // here you can start your UI component if needed
   console.log("JMap is started and my extension has been successfuly started")
 }
})

It returns all extension mouseover data for a specific layer and feature.

example

const feature = ...
// returns all extension mouseover data for the feature
JMap.Extension.renderMouseOver(2, feature)
