Class PConstraintInfo

java.lang.Object

org.eclipse.incquery.runtime.localsearch.planner.PConstraintInfo

public class PConstraintInfo
extends java.lang.Object

Wraps a PConstraint together with information required for the planner. Currently contains information about the expected binding state of the affected variables also called application condition, and the cost of the enforcement, based on the meta and/or the runtime context.

Constructor Detail

PConstraintInfo

public PConstraintInfo(PConstraint constraint,
                       java.util.Set<PVariable> boundMaskVariables,
                       java.util.Set<PVariable> freeMaskVariables,
                       java.util.Set<PConstraintInfo> sameWithDifferentBindings,
                       IQueryRuntimeContext runtimeContext)

Instantiates the wrapper

Parameters:

constraintfor - which the information is added and stored

boundMaskVariablesthe - bound variables in the operation mask

freeMaskVariablesthe - free variables in the operation mask

sameWithDifferentBindingsduring - the planning process, multiple operation adornments are considered for a constraint, so that it is represented by multiple plan infos. This parameter contains all plan infos that are for the same constraint, but with different adornment

runtimeContextthe - runtime query context
