Constructor Details

AbstractTargetedConstraints

protected AbstractTargetedConstraints(@NonNull
 ISource source,
 @NonNull
 Supplier<List<IMetapathExpression>> targets,
 @NonNull
 T constraints)

Construct a new set of targeted constraints.

Parameters:

source - information about the resource the constraints were sources from

targets - a supplier to get the Metapath expressions that can be used to find matching targets

constraints - the constraints to apply to matching targets

Method Details

getSource

public ISource getSource()

Description copied from interface: IValueConstrained

Get information about the resource the constraints were loaded from.

Specified by:

getSource in interface IValueConstrained

Returns:

the source information

getTargets

public List<IMetapathExpression> getTargets()

Description copied from interface: ITargetedConstraints

Get the Metapath expressions used to identify the targets of the constraint.

Specified by:

getTargets in interface ITargetedConstraints

Returns:

the Metapath expressions identifying the targets of the associated constraints

getConstraintSupport

public T getConstraintSupport()

Description copied from interface: IFeatureValueConstrained

Lazy initialize the instances for the constraints when the constraints are first accessed.

Specified by:

getConstraintSupport in interface IFeatureValueConstrained

Returns:

the constraints instance

applyTo

protected void applyTo(@NonNull
 IValueConstrained definition)

Apply the constraints to the provided definition.

This will be called when a definition is found that matches the target expression.

Parameters:

definition - the definition to apply the constraints to.

target

public void target(IFlagDefinition definition)

Description copied from interface: ITargetedConstraints

Apply the constraint to the provided definition.

Specified by:

target in interface ITargetedConstraints

Parameters:

definition - the definition to apply the constraint to

target

public void target(IFieldDefinition definition)

Description copied from interface: ITargetedConstraints

Apply the constraint to the provided definition.

Specified by:

target in interface ITargetedConstraints

Parameters:

definition - the definition to apply the constraint to

target

public void target(IAssemblyDefinition definition)

Description copied from interface: ITargetedConstraints

Apply the constraint to the provided definition.

Specified by:

target in interface ITargetedConstraints

Parameters:

definition - the definition to apply the constraint to

wrongDefinitionTypeTargeted

protected void wrongDefinitionTypeTargeted(@NonNull
 IDefinition definition)

Throws a ConstraintInitializationException indicating that the constraint target is not valid.

Parameters:

definition - the targeted definition

Throws:

ConstraintInitializationException - when method is called to indicate that the provided definition is not a valid constraint target
