Class ExecutableMetaData

  • All Implemented Interfaces:
    Iterable<MetaConstraint<?>>, ConstraintMetaData
    public class ExecutableMetaData
extends AbstractConstraintMetaData
    An aggregated view of the constraint related meta data for a given method or constructors and in (case of methods) all the methods in the inheritance hierarchy which it overrides or implements.

    Instances are retrieved by creating a ExecutableMetaData.Builder and adding all required ConstrainedExecutable objects to it. Instances are read-only after creation.

    Identity is solely based on the method's name and parameter types, hence sets and similar collections of this type may only be created in the scope of one Java type.

    • Method Detail

      • getParameterMetaData

        public ParameterMetaData getParameterMetaData​(int parameterIndex)
        Returns meta data for the specified parameter of the represented executable.
        Parameters:
        parameterIndex - the index of the parameter
        Returns:
        Meta data for the specified parameter. Will never be null.

      • getParameterTypes

        public Class<?>[] getParameterTypes()

      • getSignatures

        public Set<Signature> getSignatures()
        Returns the signature(s) of the method represented by this meta data object, based on the represented executable's name and its parameter types.
        Returns:
        The signatures of this meta data object. Will only contain more than one element in case the represented method represents a sub-type method overriding a super-type method using a generic type parameter in its parameters.

      • getCrossParameterConstraints

        public Set<MetaConstraint<?>> getCrossParameterConstraints()
        Returns the cross-parameter constraints declared for the represented method or constructor.
        Returns:
        the cross-parameter constraints declared for the represented method or constructor. May be empty but will never be null.

      • asDescriptor

        public ExecutableDescriptorImpl asDescriptor​(boolean defaultGroupSequenceRedefined,
                                             List<Class<?>> defaultGroupSequence)
        Description copied from interface: ConstraintMetaData
        Returns this meta data object's corresponding representation in the descriptor model.
        Parameters:
        defaultGroupSequenceRedefined - Whether the bean hosting the represented element has a redefined default group sequence or not.
        defaultGroupSequence - The default group sequence of the bean hosting the represented element.
        Returns:
        This meta data object's corresponding descriptor model representation. Implementations should return a specific sub type of ElementDescriptor.
