net.ssehub.easy.reasoning.sseReasoner.functions.AbstractConstraintProcessor

net.ssehub.easy.reasoning.sseReasoner.Resolver.OtherConstraintsProcessor

Enclosing class:

Resolver

private class Resolver.OtherConstraintsProcessor
extends AbstractConstraintProcessor

Implements a processor for constraints, for which variables (including the variable mapping) shall be substituted and the result shall be added to Resolver.otherConstraints. Call #setParameter(CompoundAccess, AbstractVariable) before processing and clear() afterwards before reuse.

Method Detail

setParameter

private void setParameter(ConstraintSyntaxTree selfEx,
                          AbstractVariable self,
                          IDecisionVariable variable)

Sets the parameters for processing.

Parameters:

selfEx - an expression representing self (ignored if null, self and selfEx shall never both be specified/not null).

self - an variable declaration representing self (ignored if null).

variable - the variable the constraints are processed for (may be null)

clear

private void clear()

Clears the parameters for reuse. Although clearing may be superfluous, it also helps getting rid of unnecessary references / supports garbage collection.

process

public ConstraintSyntaxTree process(ConstraintSyntaxTree cst,
                                    AbstractConstraintProcessor.ExpressionType type,
                                    java.lang.String slot,
                                    IModelElement parent)

Description copied from class: AbstractConstraintProcessor

Processes a constraint syntax tree.

Specified by:

process in class AbstractConstraintProcessor

Parameters:

cst - the constraint syntax tree

type - the type of cst

slot - the slot name, only in case of AbstractConstraintProcessor.ExpressionType.DEFAULT or AbstractConstraintProcessor.ExpressionType.ANNOTATION_DEFAULT

parent - the actual/intended parent if not determined otherwise

Returns:

the processed constraint syntax tree, may be cst

getContextStack

public ContextStack getContextStack()

Description copied from class: AbstractConstraintProcessor

Returns the context stack, e.g., for type exclusions.

Specified by:

getContextStack in class AbstractConstraintProcessor

Returns:

the context stack
