Class Detail

orion.textview.ProjectionTextModel(baseModel)

Constructs a new ProjectionTextModel based on the specified TextModel.

Parameters:
{orion.textview.TextModel} baseModel: The base text model.

Method Detail

addEventListener(type, listener, useCapture)

Adds an event listener to this event target.
Defined in: </shared/eclipse/e4/orion/I201301232230/plugins/org.eclipse.orion.client.editor/web/orion/textview/eventTarget.js>.

Parameters:
{String} type: The event type.
{Function|EventListener} listener: The function or the EventListener that will be executed when the event happens.
{Boolean} useCapture Optional, Default: false: true if the listener should be trigged in the capture phase.

See:: #removeEventListener

addProjection(projection)

Adds a projection range to the model.

The model must notify the listeners before and after the the text is changed by calling #onChanging and #onChanged respectively.

Parameters:
{orion.textview.Projection} projection: The projection range to be added.

See:: #removeProjection

dispatchEvent(evt)

Defined in: </shared/eclipse/e4/orion/I201301232230/plugins/org.eclipse.orion.client.editor/web/orion/textview/eventTarget.js>.

Parameters:
{Event} evt: The event to dispatch.

Returns all projection ranges of this model.

Returns:: {orion.textview.Projection[]} The projection ranges.

See:: #addProjection

getText(start, end)

Parameters:
start
end

See:: orion.textview.TextModel#getText

{Number} mapOffset(offset, baseOffset)

Maps offsets between the projection model and its base model.

Parameters:
{Number} offset: The offset to be mapped.
{Boolean} baseOffset Optional, Default: false: true if offset is in base model and should be mapped to the projection model.

Returns:: {Number} The mapped offset

onChanged(modelChangedEvent)
