Class ConditionFactory.KeyCondition

java.lang.Object

org.openstreetmap.josm.gui.mappaint.mapcss.ConditionFactory.KeyCondition

All Implemented Interfaces:

Condition, Condition.TagCondition

Enclosing class:

ConditionFactory

public static class ConditionFactory.KeyCondition
extends java.lang.Object
implements Condition.TagCondition

KeyCondition represent one of the following conditions in either the link or the primitive context:

     ["a label"]  PRIMITIVE:   the primitive has a tag "a label"
                  LINK:        the parent is a relation and it has at least one member with the role
                               "a label" referring to the child

     [!"a label"]  PRIMITIVE:  the primitive doesn't have a tag "a label"
                   LINK:       the parent is a relation but doesn't have a member with the role
                               "a label" referring to the child

     ["a label"?]  PRIMITIVE:  the primitive has a tag "a label" whose value evaluates to a true-value
                   LINK:       not supported

     ["a label"?!] PRIMITIVE:  the primitive has a tag "a label" whose value evaluates to a false-value
