Enum Class LabelBarrierWeight

All Implemented Interfaces:
Serializable, Comparable<LabelBarrierWeight>, Constable

public enum LabelBarrierWeight extends Enum<LabelBarrierWeight>
The weight of features when considered as barriers to labeling.

An AnnotationLayer or a DimensionLayer, which has no LabelDefinition of its own, can be added to a map's operational layers. Their features will be automatically considered by the labeling process, to block labels being placed overlapping the features. This LabelBarrierWeight property controls how much labels must avoid the layer's features.

Note: Other layer types, which have their own LabelDefinition, can also have their features treated as barriers, but this is controlled by their LabelDefinition.getFeatureBoundaryOverlapStrategy() and LabelDefinition.getFeatureInteriorOverlapStrategy() properties.

Since:

  • Enum Constant Details

    • NONE

      public static final LabelBarrierWeight NONE
      The feature will not act as an barrier to labels.
      Since:
      100.14.0
    • LOW

      public static final LabelBarrierWeight LOW
      The feature will be avoided by labels unless that's the only way they can be placed.

      Labels will still overlap this feature if that is the only way they can be placed.

      Since:
      100.14.0
    • MEDIUM

      public static final LabelBarrierWeight MEDIUM
      The feature will be avoided by labels unless that's the only way they can be placed after trying some additional positions.

      Labels will still overlap this feature if that is the only way they can be placed. This is similar to LOW, but the labeling process can try additional intermediate alternative positions. Not all styles of labeling will have additional positions to try.

      Since:
      100.14.0
    • HIGH

      public static final LabelBarrierWeight HIGH
      The feature is an exclusion zone for labels.

      Labels that overlap the feature will not be placed unless the label is using a deconfliction strategy of LabelDeconflictionStrategy.NONE or LabelDeconflictionStrategy.DYNAMIC_NEVER_REMOVE.

  • Method Details

    • values

      public static LabelBarrierWeight[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared
    • valueOf

      public static LabelBarrierWeight valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
