Method Summary

Methods

Modifier and Type	Method and Description
boolean	areParametersConstrained() Returns true if the executable parameters are constrained either: because of a constraint on at least one of the parameters because of a cascade on at least one of the parameters (via @Valid) because of at least one cross-parameter constraint Also returns false if there is no parameter.
ElementDescriptor.ConstraintFinder	findConstraints() Find cross-parameter constraints and potentially restricts them to certain criteria.
Set<ConstraintDescriptor<?>>	getConstraintDescriptors() Return all constraint descriptors for all cross-parameter constraints of this executable or an empty Set if none are present.
String	getName() Returns the method name in case this descriptor represents a method or the non-qualified name of the declaring class in case this descriptor represents a constructor.
List<ParameterDescriptor>	getParameterDescriptors() Returns a list with descriptors for this executable's parameters.
ReturnValueDescriptor	getReturnValueDescriptor() Returns a descriptor for this executable's return value.
boolean	hasConstraints() Whether this executable has any cross-parameter constraints.
boolean	isReturnValueConstrained() Returns true if the executable return value is constrained either: because of a constraint on the return value because validation is cascaded on the return value (via @Valid) Also returns false if there is no return value.

Method Detail

getName

String getName()

Returns the method name in case this descriptor represents a method or the non-qualified name of the declaring class in case this descriptor represents a constructor.

Returns:

The name of the executable represented by this descriptor.

getParameterDescriptors

List<ParameterDescriptor> getParameterDescriptors()

Returns a list with descriptors for this executable's parameters. The size of this list corresponds to the number of this executable's parameters.

Returns:

A list with descriptors for this executable's parameters. An empty list will be returned if this executable has no parameters, but never null.

getReturnValueDescriptor

ReturnValueDescriptor getReturnValueDescriptor()

Returns a descriptor for this executable's return value.

Returns:

A descriptor for this executable's return value or null if this executable has no return value.

areParametersConstrained

boolean areParametersConstrained()

Returns true if the executable parameters are constrained either:

• because of a constraint on at least one of the parameters
• because of a cascade on at least one of the parameters (via @Valid)
• because of at least one cross-parameter constraint

Also returns false if there is no parameter.

Returns:

true if the executable parameters are constrained

isReturnValueConstrained

boolean isReturnValueConstrained()

Returns true if the executable return value is constrained either:

• because of a constraint on the return value
• because validation is cascaded on the return value (via @Valid)

Also returns false if there is no return value.

Returns:

true if the executable return value is constrained

hasConstraints

boolean hasConstraints()

Whether this executable has any cross-parameter constraints.

Specified by:

hasConstraints in interface ElementDescriptor

Returns:

true if this executable has at least one cross-parameter constraint, false otherwise.

getConstraintDescriptors

Set<ConstraintDescriptor<?>> getConstraintDescriptors()

Return all constraint descriptors for all cross-parameter constraints of this executable or an empty Set if none are present. In particular, constraints on individual parameters and return value constraints are not returned.

Specified by:

getConstraintDescriptors in interface ElementDescriptor

Returns:

Set of cross-parameter constraint descriptors for this element

findConstraints

ElementDescriptor.ConstraintFinder findConstraints()

Find cross-parameter constraints and potentially restricts them to certain criteria. Neither constraints on individual parameters nor return value constraints are taken into account.

Specified by:

findConstraints in interface ElementDescriptor

Returns:

Constraint finder object.
