@Incubating
public interface ContainerElementTarget

Facet of a constraint mapping creational context which allows to select a type argument or the component type of the (return) type of the current property, parameter or method as target for the next operations.

Method Summary

Modifier and Type	Method and Description
ContainerElementConstraintMappingContext	containerElementType() Selects the single type argument of the current element's generic type as the target for the next operations.
ContainerElementConstraintMappingContext	containerElementType(int index, int... nestedIndexes) Selects the single type argument of the current element's generic type as the target for the next operations.

Method Detail

containerElementType

ContainerElementConstraintMappingContext containerElementType()

Selects the single type argument of the current element's generic type as the target for the next operations. Selects the component type if the current element is of an array type.

Returns:

A creational context representing the single type argument or the component type of the current element's type.

Throws:

ValidationException - If the given element (property, return value or parameter) is not of a generic type nor of an array type or is a generic type but has more than one type argument.

containerElementType

ContainerElementConstraintMappingContext containerElementType(int index,
                                                              int... nestedIndexes)

Selects the single type argument of the current element's generic type as the target for the next operations. Selects the component type if the current element is of an array type.

Parameters:

index - The index of the type argument to configure. Pass 0 when navigating into an array type.

nestedIndexes - the nested index(es) in case the container element to configure is a generic type within another generic type, e.g. List<Map<String, String>>, a multi-dimensional array or a combination of (nested) parameterized and array types.

Returns:

A creational context representing the specified type argument.

Throws:

ValidationException - If the given element (property, return value or parameter) is not of a generic type nor of an array type or is a generic type but has no type argument with the given index.
