Method Detail

evaluate

public boolean evaluate(ExecutionEnvironment environment)

Description copied from interface: Proposition

This method evaluates this proposition -- and in the case of Propositions containing children, those children as well -- and returns the boolean result;

Specified by:

evaluate in interface Proposition

Parameters:

environment - the ExecutionEnvironment that this Proposition is running in

Returns:

the boolean result of evaluation

Throws:

TermResolutionException - if there is a problem resolving the Term

See Also:

Proposition.evaluate(org.kuali.rice.krms.api.engine.ExecutionEnvironment)

compare

protected boolean compare(Comparable<T> termValue)

This method does the actual comparison of the term value w/ the expected value

Parameters:

termValue -

Returns:

the boolean result of the comparison

getChildren

public List<Proposition> getChildren()

Description copied from interface: Proposition

This method returns the List of child Propositions that belong to this object. If there are no children (e.g. for simple Proposition types), this must return an empty List.

Specified by:

getChildren in interface Proposition

Returns:

a List containing any child Propositions that belong to this object. Must never return null.

isCompound

public boolean isCompound()

Description copied from interface: Proposition

Indicates whether this Proposition can have children.

Specified by:

isCompound in interface Proposition

Returns:

true if this Proposition can contain child Propositions.

getExpectedValue

protected T getExpectedValue()

Returns:

the expectedValue

toString

public String toString()

Overrides:

toString in class Object
