This event is triggered after the map context is applied.

You can access extension's data from this event, see example below.

example

// Triggered after a map-context is applied
JMap.Event.MapContext.on.afterApply("my-after-apply-listener", params => {
  console.info(`After apply map context id="${params.context.title}"`, params.context)
  const isExtensionDataSet = params.isExtensionDataSetById("my-extension")
  if (!isExtensionDataSet) {
    console.info("No extension data in map-context")
  } else {
    console.info("Extension map context data = ", params.getExtensionDataById("my-extension"))
  }
})

This event is triggered after a context map data is created or updated.

This event is not triggered when a context metadata is changed: title, description, default context, etc...

You can access extension data from this event, see example below.

example

// Triggered after a map-context is created or updated
JMap.Event.MapContext.on.afterMapDataChange("my-after-map-data-change-listener", params => {
  console.info(`After map data change for context id="${params.context.title}"`, params.context)
  console.info(`Is creation ="${params.isCreation}"`) // creation or update
  const isExtensionDataSet = params.isExtensionDataSetById("my-extension")
  if (isExtensionDataSet) {
    console.info("Saved extension data", params.getExtensionDataById("my-extension"))
  } else {
    console.info("No extension data")
  }
})

This event is triggered when an error occurs while applying a map-context.

example

// Triggered after a map-context error occurs
JMap.Event.MapContext.on.applyError("my-apply-error-listener", params => {
  console.info(`An error occured while applying map context id="${params.context.title}"`, params.context)
})

This event is triggered before the map context is applied.

You can access extension's data from this event, see example below.

example

// Triggered before a map-context is applied
JMap.Event.MapContext.on.beforeApply("my-before-apply-listener", params => {
  console.info(`Before apply map context id="${params.context.title}"`, params.context)
  const isExtensionDataSet = params.isExtensionDataSetById("my-extension")
  if (!isExtensionDataSet) {
    console.info("No extension data in map-context")
  } else {
    console.info("Extension map context data = ", params.getExtensionDataById("my-extension"))
  }
})

This event is triggered before a context map data is created or updated.

This event is not triggered when a context metadata is changed: title, description, default context, etc...

You can access and manage extension's data from this event, see example below.

example

// Triggered before a map-context is created or updated
JMap.Event.MapContext.on.beforeMapDataChange("my-before-map-data-changed-listener", params => {
  console.info(`Before map data changed for context id="${params.context.title}"`, params.context)
  console.info(`Is creation ="${params.isCreation}"`) // creation or update
  // you can check if some extension data has been set for this map-context
  const isExtensionDataSet = params.isExtensionDataSetById("my-extension")
  if (isExtensionDataSet) {
    // and you can delete this data if you want
    params.removeExtensionDataById("my-extension")
  }
  // it's not necessary to delete before setting the data, update will overwrite the existing data
  params.setExtensionDataById("my-extension", { count: 0, description: "your own extension data" })
  console.info("Extension data has been set and will be saved", params.getExtensionDataById("my-extension"))
})

This event is triggered when the map-context service is initialized.

example

// Triggered when map context is initialized
JMap.Event.MapContext.on.initialized("custom-initialized-listener", params =>
  console.info("Map context service initialized", params)
)
