Class Constraint<T>

  • Type Parameters:
    T - The type of object that decisions will be made.
    Direct Known Subclasses:
    ProgramConstraint
    public abstract class Constraint<T>
extends java.lang.Object
    Constraints are used to make decisions to traverse a decision tree where each node in the tree has a constraint that is used to decide if that node is part of the successful decision path.

      • Constraint

        public Constraint​(java.lang.String name)
        Constructor takes the name of the constraint. This name will be tag used in the XML specification file.
        Parameters:
        name - the name of the constraint

    • Method Detail

      • getName

        public final java.lang.String getName()
        Returns the name of the constraint. Note: this name is also the XML tag used in the constraints specification files.
        Returns:
        the name of the constraint

      • isSatisfied

        public abstract boolean isSatisfied​(T t)
        Returns true if the given object satisfies this constraint.
        Parameters:
        t - the object to test this constraint on.
        Returns:
        true if the given object satisfies this constraint.

      • loadConstraintData

        public abstract void loadConstraintData​(ConstraintData data)
        Initialized this constraint state. Attributes in the xml element with this constaints tag name will be extracted into the ConstraintData object for easy retrieval.
        Parameters:
        data - the ConstraintData object used to initialize this constraint.

      • equals

        public abstract boolean equals​(java.lang.Object obj)
        Overrides:
        equals in class java.lang.Object

      • getDescription

        public abstract java.lang.String getDescription()
        Returns a description of this constraint (with its configuration data) to be used to journal the decision path that was taken.
        Returns:
        a description of this constraint with its configuration data.
