net.ssehub.easy.instantiation.core.model.vilTypes.configuration.ConfigurationContextResolver

class ConfigurationContextResolver
extends java.lang.Object

Resolves the context around changed variables, including their parent variables, their references and the variables referencing them. Create an instance, call resolve() and obtain the result from variables(), attributes() and filter().

Constructor Detail

ConfigurationContextResolver

public ConfigurationContextResolver(Configuration configuration,
                                    java.util.Set<AbstractIvmlVariable> changed)

Creates a context resolver.

Parameters:

configuration - the configuration to resolve within

changed - the changed variables to resolve the context for

Method Detail

resolve

public void resolve()

Resolve the context.

map

private void map(IDecisionVariable var,
                 boolean viaParent)

Map the variable and its nested variables to the configuration and follows references.

Parameters:

var - the variable to map

viaParent - was this called via a parent recursion?

mapVar

private void mapVar(IDecisionVariable var,
                    boolean resolve,
                    boolean viaParent)

Map the variable (without nested) to the configuration and follows references, but only if frozen.

Parameters:

var - the variable to map

resolve - consider decVar for reverse reference resolution

viaParent - was called via parent recursion

createVilInstance

private AbstractIvmlVariable createVilInstance(IDecisionVariable decVar,
                                               Configuration configuration)

Obtains a mapping instance from configuration or creates a new one.

Parameters:

decVar - the decision variable to obtain or create

configuration - the configuration for lookup

Returns:

the mapper instance

augment

private void augment(IDecisionVariable dVar,
                     boolean viaParent)

Augments dVar and its transitive parents.

Parameters:

dVar - the decision variable to augment

viaParent - was called via parent recursion

collectReferences

private java.util.Map<AbstractVariable,java.util.List<IDecisionVariable>> collectReferences()

Collects all references in the configuration.

Returns:

all references in terms of a reference target - referring elements maps

collectReferences

private void collectReferences(IDecisionVariable var,
                               java.util.Map<AbstractVariable,java.util.List<IDecisionVariable>> references)

Collects the references for a single variable.

Parameters:

var - the variable to collect the references for

references - the references in terms of a reference target - referring elements maps (modified as a side effect)

collectReference

private void collectReference(IDecisionVariable var,
                              Value val,

Collects the references for a variable and a single value (entry in case of a collection).

Parameters:

var - the variable to collect the references for

val - the value (entry)

references - the references in terms of a reference target - referring elements maps (modified as a side effect)
