public class AbstractConstraintCheck
extends Object
implements ConstraintCheck

Abstract base class for ConstraintCheck implementations. Concrete checks should only override those check methods applicable for their supported element types.

For instance would a check ensuring that constraint annotations are only given at non-static fields or methods only override checkField() and checkMethod().

All check methods not overridden will return an empty list.

Method Detail

checkField

public Set<ConstraintCheckError> checkField(VariableElement element,
                                            AnnotationMirror annotation)

Description copied from interface: ConstraintCheck

Checks, whether the given annotation is allowed at the given field.

Specified by:

checkField in interface ConstraintCheck

Parameters:

element - An annotated field.

annotation - An annotation at that field.

Returns:

A set with errors, that describe, why the given annotation is not allowed at the given element. In case no errors occur (the given annotation is allowed at the given element), an empty set must be returned.

checkMethod

public Set<ConstraintCheckError> checkMethod(ExecutableElement element,
                                             AnnotationMirror annotation)

Description copied from interface: ConstraintCheck

Checks, whether the given annotation is allowed at the given method.

Specified by:

checkMethod in interface ConstraintCheck

Parameters:

element - An annotated method.

annotation - An annotation at that method.

Returns:

A set with errors, that describe, why the given annotation is not allowed at the given element. In case no errors occur (the given annotation is allowed at the given element), an empty set must be returned.

checkAnnotationType

public Set<ConstraintCheckError> checkAnnotationType(TypeElement element,
                                                     AnnotationMirror annotation)

Description copied from interface: ConstraintCheck

Checks, whether the given annotation is allowed at the given annotation type declaration.

Specified by:

checkAnnotationType in interface ConstraintCheck

Parameters:

element - An annotated annotation type declaration.

annotation - An annotation at that annotation type.

Returns:

A set with errors, that describe, why the given annotation is not allowed at the given element. In case no errors occur (the given annotation is allowed at the given element), an empty set must be returned.

checkNonAnnotationType

public Set<ConstraintCheckError> checkNonAnnotationType(TypeElement element,
                                                        AnnotationMirror annotation)

Description copied from interface: ConstraintCheck

Checks, whether the given annotation is allowed at the given type declaration (class, interface, enum).

Specified by:

checkNonAnnotationType in interface ConstraintCheck

Parameters:

element - An annotated type declaration.

annotation - An annotation at that type.

Returns:

A set with errors, that describe, why the given annotation is not allowed at the given element. In case no errors occur (the given annotation is allowed at the given element), an empty set must be returned.
