Constructor Detail

AbstractConfigurationStatisticsVisitor

protected AbstractConfigurationStatisticsVisitor(AbstractConfigurationStatisticsVisitor.ConfigStatistics statistics)

Sole constructor of this class.

Parameters:

statistics - A data object to store the statistical information.

Method Detail

visitConfiguration

public void visitConfiguration(Configuration configuration)

Description copied from class: AbstractConfigurationVisitor

Visits a configuration.

Specified by:

visitConfiguration in interface IConfigurationVisitor

Overrides:

visitConfiguration in class AbstractConfigurationVisitor

Parameters:

configuration - the configuration to visit

visitDecisionVariable

public void visitDecisionVariable(IDecisionVariable variable)

Description copied from interface: IConfigurationVisitor

Visits a decision variable.

Parameters:

variable - the decision variable to visit

visitVariable

public void visitVariable(IDecisionVariable variable,
                          boolean nestedInContainer)

Recursive part to visit all (nested) variables.

Parameters:

variable - The visited decision variable instance.

nestedInContainer - true if the parent is a container, false otherwise.

visitRefines

private void visitRefines(Compound cmp)

Visits all refined compounds and collects statistics.

Parameters:

cmp - the compound to visit

processEvalConstraints

protected void processEvalConstraints(PartialEvaluationBlock evalBlock)

Processes constraints within an eval-block.

Parameters:

evalBlock - the block to process

visitVariableContainer

protected void visitVariableContainer(IDecisionVariableContainer cnt)

Processes elements within a variable container.

Parameters:

cnt - the container

visitAssignment

protected void visitAssignment(AttributeAssignment assng)

Processes attribute assignments.

Parameters:

assng - the assignment

getStatistics

public AbstractConfigurationStatisticsVisitor.ConfigStatistics getStatistics()

Returns the collected statistics.

Returns:

The collected statistics, will be empty if the visit method was not called before.

specialTreatment

protected abstract void specialTreatment(IDecisionVariable variable)

Optional hook to realize additional statistics for (nested) variables.

Parameters:

variable - A visited variable. This will be called for all variables, independently if they are m toplevel variables or if they are nested.

specialTreatment

protected abstract void specialTreatment(Project mainProject)

Optional hook to realize additional statistics for the underlying IVML project.

Parameters:

mainProject - Configuration.getProject().

visitConstraint

protected void visitConstraint(Constraint constraint)

Processes a constraint. Added later, so default implementation is empty.

Parameters:

constraint - the constraint to process (contained constraint may be null)

visitDefaultValue

protected void visitDefaultValue(ConstraintSyntaxTree constraint)

Processes a default value. Added later, so default implementation is empty.

Parameters:

constraint - the constraint to process (may be null)

visitOperationDefinition

protected void visitOperationDefinition(OperationDefinition opdef)

Processes an operation definition. Added later, so default implementation is empty.

Parameters:

opdef - the operation definition
