Class: Splitter

ol.interaction. Splitter

new Splitter(options)

Interaction splitter: acts as a split feature agent while editing vector features (LineString).

Parameters:
Name Type Description
options olx.interaction.SplitOptions

source {ol.source.Vector|Array{ol.source.Vector}} The target source (or array of source) with features to be split (configured with useSpatialIndex set to true)

- triggerSource {ol.source.Vector} Any newly created or modified features from this source will be used to split features on the target source. If none is provided the target source is used instead.
- features {ol.Collection.<ol.Feature>} A collection of feature to be split (replace source target).
- triggerFeatures {ol.Collection.<ol.Feature>} Any newly created or modified features from this collection will be used to split features on the target source (replace triggerSource).
- filter {function|undefined} a filter that takes a feature and return true if the feature is eligible for splitting, default always split.
- tolerance {function|undefined} Distance between the calculated intersection and a vertex on the source geometry below which the existing vertex will be used for the split. Default is 1e-10.
To Do:
  • verify auto intersection on features that split.
Fires:
  • beforesplit,event: aftersplit
