Class ConstraintFactory

java.lang.Object
  org.eclipse.emf.validation.service.ConstraintFactory

public abstract class ConstraintFactory
extends Object

A constraint factory creates constraint implementations from descriptors. The intent is to support registration of custom factory implementations, but currently, the only implementation is the XmlConstraintFactory.

This class is not intended to be used outside of the validation framework.

Constructor Summary

protected

ConstraintFactory() Initializes me.

Method Summary

protected abstract IModelConstraint	createConstraint(IConstraintDescriptor descriptor) Implemented by subclasses to do the hard work of creating a constraint.
protected abstract IModelConstraint	createConstraint(IXmlConstraintDescriptor descriptor) Deprecated. Use the createConstraint(IConstraintDescriptor) method, instead
static ConstraintFactory	getInstance() Obtains the currently registered factory instance.
IModelConstraint	newConstraint(IConstraintDescriptor descriptor) Creates the constraint represented by the specified descriptor.
IModelConstraint	newConstraint(IXmlConstraintDescriptor descriptor) Deprecated. Use the newConstraint(IConstraintDescriptor) method, instead

protected ConstraintFactory()

Initializes me.

Method Detail

getInstance

public static ConstraintFactory getInstance()

Obtains the currently registered factory instance.

Returns:

the constraint factory instance

newConstraint

@Deprecated
public final IModelConstraint newConstraint(IXmlConstraintDescriptor descriptor)

Deprecated. Use the newConstraint(IConstraintDescriptor) method, instead

Creates the constraint represented by the specified descriptor. This method never fails to return a valid constraint implementation (though it may be a proxy for a disabled constraint if the descriptor is invalid). This method delegates to the superclass implementation of the createConstraint(org.eclipse.emf.validation.xml.IXmlConstraintDescriptor) method.

Parameters:

descriptor - the constraint descriptor

Returns:

the corresponding constraint implementation

See Also:

createConstraint(org.eclipse.emf.validation.xml.IXmlConstraintDescriptor)

createConstraint

@Deprecated
protected abstract IModelConstraint createConstraint(IXmlConstraintDescriptor descriptor)

Deprecated. Use the createConstraint(IConstraintDescriptor) method, instead

Implemented by subclasses to do the hard work of creating a constraint.

Parameters:

descriptor - a descriptor of the constraint to be created

Returns:

the appropriate implementation of the constraint

newConstraint

public final IModelConstraint newConstraint(IConstraintDescriptor descriptor)

Creates the constraint represented by the specified descriptor. This method never fails to return a valid constraint implementation (though it may be a proxy for a disabled constraint if the descriptor is invalid). This method delegates to the superclass implementation of the createConstraint(org.eclipse.emf.validation.xml.IXmlConstraintDescriptor) method.

Parameters:

descriptor - the constraint descriptor

Returns:

the corresponding constraint implementation

Since:

createConstraint

protected abstract IModelConstraint createConstraint(IConstraintDescriptor descriptor)

Implemented by subclasses to do the hard work of creating a constraint.

Parameters:

descriptor - a descriptor of the constraint to be created

Returns:

the appropriate implementation of the constraint

Since:

1.1
