Class SimplePropositionTypeService

java.lang.Object
org.kuali.rice.krms.impl.provider.repository.SimplePropositionTypeService
All Implemented Interfaces:
PropositionTypeService
public class SimplePropositionTypeService extends Object implements PropositionTypeService
A default implementation of PropositionTypeService for propositions which are composed of terms, operators, and functions. A simple proposition is self-contained and has no compound "sub" propositions. However, it's behavior is defined by the set of parameters on the PropositionDefinition.

    • loadProposition

      public Proposition loadProposition(org.kuali.rice.krms.api.repository.proposition.PropositionDefinition propositionDefinition)
      Specified by:
      loadProposition in interface PropositionTypeService

    • translateToExpression

      protected Expression<Boolean> translateToExpression(org.kuali.rice.krms.api.repository.proposition.PropositionDefinition propositionDefinition)
      Translates the parameters on the given proposition definition to create an expression for evaluation. The proposition parameters are defined in a reverse-polish notation so a stack is used for evaluation purposes.
      Parameters:
      propositionDefinition - the proposition definition to translate
      Returns:
      the translated expression for the given proposition, this expression, when evaluated, will return a Boolean.
