Class CoordPair

java.lang.Object
com.adobe.xfa.ut.CoordPair

public final class CoordPair extends Object
A class to describe a coordinate (in Euclidean space). It consists of a pair of (x, y) values.

Instances of this class are immutable. All change operations return a new instance of this CoordPair class.

    • equals

      public boolean equals(Object object)
      Determines if this object is equal to the given Object. Comparisons with instances of non-CoordPair objects are never equal. When comparing instances of CoordPair objects, the object's UnitSpan coordinates are each compared for equality.
      Overrides:
      equals in class Object
      Parameters:
      object - the Object to compare.
      Returns:
      true if equal, false otherwise.

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object
    • notEquals

      public boolean notEquals(Object compare)
      Determines if this object is not equal to the given Object. Comparisons with instances of non-CoordPair objects are always not equal. When comparing instances of CoordPair objects, the object's UnitSpan coordinates are each compared for inequality.
      Parameters:
      compare - the Object to compare.
      Returns:
      true if not equal, false othewise.

    • add

      public CoordPair add(CoordPair add)
