      • getDeclaredConstructors

        static java.util.List<javax.lang.model.element.ExecutableElement> getDeclaredConstructors​(javax.lang.model.element.TypeElement type)
        Retrieves the list of declared constructors from the provided TypeElement.

        This method provides a null-safe way to obtain the constructors of a given type. If the input type is null, an empty list is returned.

        Parameters:
        type - the TypeElement representing the type to retrieve constructors from
        Returns:
        a List of ExecutableElement objects representing the declared constructors; never null, but may be empty if no constructors are found or if the input is null

      • getDeclaredConstructors

        static java.util.List<javax.lang.model.element.ExecutableElement> getDeclaredConstructors​(javax.lang.model.type.TypeMirror type)
        Retrieves the list of declared constructors from the provided TypeMirror.

        This method provides a null-safe way to obtain the constructors of a given type. If the input type is null, an empty list is returned.

        Parameters:
        type - the TypeMirror representing the type to retrieve constructors from
        Returns:
        a List of ExecutableElement objects representing the declared constructors; never null, but may be empty if no constructors are found or if the input is null

      • findConstructor

        static javax.lang.model.element.ExecutableElement findConstructor​(javax.lang.model.element.TypeElement type,
                                                                  java.lang.reflect.Type... parameterTypes)
        Finds a declared constructor in the specified TypeElement that matches the given parameter types.

        This method provides a null-safe way to locate a constructor based on its parameter types. If the input type is null, or no matching constructor is found, null is returned.

        Parameters:
        type - the TypeElement representing the type to search for constructors
        parameterTypes - the array of Type objects representing the parameter types to match
        Returns:
        the matched ExecutableElement representing the constructor; may be null

      • findConstructor

        static javax.lang.model.element.ExecutableElement findConstructor​(javax.lang.model.type.TypeMirror type,
                                                                  java.lang.reflect.Type... parameterTypes)
        Finds a declared constructor in the specified TypeMirror that matches the given parameter types.

        This method provides a null-safe way to locate a constructor based on its parameter types. If the input type is null, or no matching constructor is found, null is returned.

        Parameters:
        type - the TypeMirror representing the type to search for constructors
        parameterTypes - the array of Type objects representing the parameter types to match
        Returns:
        the matched ExecutableElement representing the constructor; may be null

      • findDeclaredConstructors

        static java.util.List<javax.lang.model.element.ExecutableElement> findDeclaredConstructors​(javax.lang.model.element.TypeElement type,
                                                                                           java.util.function.Predicate<? super javax.lang.model.element.ExecutableElement>... constructorFilters)
        Retrieves and filters the list of declared constructors from the provided TypeElement.

        This method provides a null-safe way to obtain the constructors of a given type. If the input type is null, an empty list is returned. The provided filters can be used to selectively include only those constructors that match the criteria.

        Parameters:
        type - the TypeElement representing the type to retrieve constructors from
        constructorFilters - optional predicates to filter the constructors; if none are provided, all constructors are included
        Returns:
        a List of ExecutableElement objects representing the filtered declared constructors; never null, but may be empty if no matching constructors are found or if the input is null

      • findDeclaredConstructors

        static java.util.List<javax.lang.model.element.ExecutableElement> findDeclaredConstructors​(javax.lang.model.type.TypeMirror type,
                                                                                           java.util.function.Predicate<? super javax.lang.model.element.ExecutableElement>... constructorFilters)
        Retrieves and filters the list of declared constructors from the provided TypeMirror.

        This method provides a null-safe way to obtain the constructors of a given type. If the input type is null, an empty list is returned. The provided filters can be used to selectively include only those constructors that match the criteria.

        Parameters:
        type - the TypeMirror representing the type to retrieve constructors from
        constructorFilters - optional predicates to filter the constructors; if none are provided, all constructors are included
        Returns:
        a List of ExecutableElement objects representing the filtered declared constructors; never null, but may be empty if no matching constructors are found or if the input is null

      • filterDeclaredConstructors

        static java.util.List<javax.lang.model.element.ExecutableElement> filterDeclaredConstructors​(javax.lang.model.type.TypeMirror type,
                                                                                             java.util.function.Predicate<? super javax.lang.model.element.ExecutableElement>... constructorFilters)
        Filters and retrieves the list of declared constructors from the provided TypeMirror.

        This method is responsible for extracting all declared constructors from the given type and applying the specified filters to narrow down the results. If the input type is null, an empty list is returned.

        Parameters:
        type - the TypeMirror representing the type to retrieve constructors from
        constructorFilters - optional predicates to filter the constructors; if none are provided, all constructors are included
        Returns:
        a List of ExecutableElement objects representing the filtered declared constructors; never null, but may be empty if no matching constructors are found or if the input is null
