Interface ILabelEngineLayerProperties2

All Superinterfaces:
Serializable
All Known Implementing Classes:
LabelEngineLayerProperties, MaplexLabelEngineLayerProperties

public interface ILabelEngineLayerProperties2
extends Serializable

Provides access to some of the main properties for labeling features.

Remarks

ILabelEngineLayerProperties2::OverposterLayerProperties is the generic way to get to the labeling properties for a layer. Depending on if the layer is being labeled with the ESRI Maplex Labeling Engine or the ESRI Standard Labeling Engine, this property will return either a MaplexOverposterLayerProperties object or a BasicOverposterLayerProperties object.

Expression is the expression that evaluates and formats the label (text).
