Interface ElementDescriptor.ConstraintFinder

Enclosing interface:

ElementDescriptor

public static interface ElementDescriptor.ConstraintFinder

Declares restrictions on retrieved constraints. Restrictions are cumulative.

A ConstraintFinder is not thread-safe. The set of matching ConstraintDescriptor is.

Method Summary

Modifier and Type	Method	Description
ElementDescriptor.ConstraintFinder	declaredOn(ElementType... types)	Restricts to the constraints hosted on the listed types for a given element.
Set<ConstraintDescriptor<?>>	getConstraintDescriptors()	Retrieves the constraint descriptors following the defined restrictions and hosted on the element described by ElementDescriptor.
boolean	hasConstraints()	Returns true if at least one constraint declaration matching the restrictions is present on the element, false otherwise.
ElementDescriptor.ConstraintFinder	lookingAt(Scope scope)	Restricts to the constraints matching the provided scope for this element.
ElementDescriptor.ConstraintFinder	unorderedAndMatchingGroups(Class<?>... groups)	Restricts to the constraints matching a given set of groups for this element.

Method Details

unorderedAndMatchingGroups

ElementDescriptor.ConstraintFinder unorderedAndMatchingGroups(Class<?>... groups)

Restricts to the constraints matching a given set of groups for this element.

This method respects group conversion, group sequences and group inheritance (including class-level Default group overriding) but does not return ConstraintDescriptors in any particular order. Specifically, ordering of the group sequence is not respected.

Parameters:

groups - groups targeted

Returns:

this following the chaining method pattern

lookingAt

ElementDescriptor.ConstraintFinder lookingAt(Scope scope)

Restricts to the constraints matching the provided scope for this element. Defaults to Scope.HIERARCHY

Parameters:

scope - expected scope

Returns:

this following the chaining method pattern

declaredOn

ElementDescriptor.ConstraintFinder declaredOn(ElementType... types)

Restricts to the constraints hosted on the listed types for a given element.

Defaults to all possible types of the element.

Typically used to restrict to fields (FIELD) or getters (METHOD).

Parameters:

types - targeted types

Returns:

this following the chaining method pattern

getConstraintDescriptors

Set<ConstraintDescriptor<?>> getConstraintDescriptors()

Retrieves the constraint descriptors following the defined restrictions and hosted on the element described by ElementDescriptor.

Returns:

matching constraint descriptors

hasConstraints

boolean hasConstraints()

Returns true if at least one constraint declaration matching the restrictions is present on the element, false otherwise.

Returns:

true if there is at least one constraint
