Method Detail

validate

public org.eclipse.emf.common.util.Diagnostic validate(org.eclipse.emf.ecore.EObject eObject)

Description copied from interface: ValidationService

Validates the given eObject.

Specified by:

validate in interface ValidationService

Parameters:

eObject - the eObject to validate

Returns:

the resulting Diagnostic, or null if the eObject is filtered by a ValidationFilter

validate

public Set<org.eclipse.emf.common.util.Diagnostic> validate(Iterator<org.eclipse.emf.ecore.EObject> eObjectsIterator)
                                                     throws ValidationCanceledException

Description copied from interface: ValidationService

Uses the given iterator to validate all eObjects in a collection.

Specified by:

validate in interface ValidationService

Parameters:

eObjectsIterator - the list to validate

Returns:

the resulting set of Diagnostics

Throws:

ValidationCanceledException - in case ValidationService.cancel() has been called

getEValidatorForEObject

protected org.eclipse.emf.ecore.EValidator getEValidatorForEObject(org.eclipse.emf.ecore.EObject eObject)

Returns a EValidator for the given EObject.

Parameters:

eObject - the EObject to retrieve a EValidator for

Returns:

the EValidator

getDiagnosticForEObject

protected org.eclipse.emf.common.util.Diagnostic getDiagnosticForEObject(org.eclipse.emf.ecore.EObject object)

Computes the Diagnostic for the given eObject.

Parameters:

object - the EObject to validate

Returns:

the Diagnostic

getValidationContext

protected Map<Object,Object> getValidationContext(org.eclipse.emf.ecore.EValidator eValidator)

Obtains the shared validation context for a validation of multiple objects or a one-off context for validation of a single object. If I have a substitution label provider, thn it will also be put into the context. Subclasses may extend this to populate the context with anything else of interest.

Parameters:

eValidator - the validator to put into the context

Returns:

the context

Description copied from interface: ValidationService

Removes a validation provider from the list of known validators.

Specified by:

removeValidator in interface ValidationService

Parameters:

validator - the Validator to remove

registerValidationFilter

public void registerValidationFilter(ValidationFilter filter)
