Method Detail

getReturnType

@NonNull
ClassElement getReturnType()

Returns:

The return type of the method

getDeclaredTypeVariables

default List<? extends GenericPlaceholderElement> getDeclaredTypeVariables()

Returns:

The type arguments declared on this method.

getReceiverType

default Optional<ClassElement> getReceiverType()

Returns the receiver type of this executable, or empty if the method has no receiver type.

A MethodElement which is an instance method, or a constructor of an inner class, has a receiver type derived from the declaring type.

A MethodElement which is a static method, or a constructor of a non-inner class, or an initializer (static or instance), has no receiver type.

Returns:

The receiver type for the method if one exists.

Since:

3.1.0

getThrownTypes

@NonNull
default ClassElement[] getThrownTypes()

Returns the types declared in the throws declaration of a method.

Returns:

The throws types, if any. Never null.

Since:

3.1.0

getParameters

@NonNull
ParameterElement[] getParameters()

Returns:

The method parameters

withNewParameters

@NonNull
MethodElement withNewParameters(@NonNull
                                         ParameterElement... newParameters)

Takes this method element and transforms into a new method element with the given parameters appended to the existing parameters.

Parameters:

newParameters - The new parameters

Returns:

A new method element

Since:

2.3.0

addAssociatedBean

@NonNull
default BeanElementBuilder addAssociatedBean(@NonNull
                                                      ClassElement type)

This method adds an associated bean using this method element as the originating element.

Note that this method can only be called on classes being directly compiled by Micronaut. If the ClassElement is loaded from pre-compiled code an UnsupportedOperationException will be thrown.

Parameters:

type - The type of the bean

Returns:

A bean builder

getSuspendParameters

@NonNull
default ParameterElement[] getSuspendParameters()

If isSuspend() returns true this method exposes the continuation parameter in addition to the other parameters of the method.

Returns:

The suspend parameters

Since:

2.3.0

hasParameters

default boolean hasParameters()

Returns true if the method has parameters.

Returns:

True if it does

isSuspend

default boolean isSuspend()

Is the method a Kotlin suspend function.

Returns:

True if it is.

Since:

2.3.0

isDefault

default boolean isDefault()

Is the method a default method on an interfaces.

Returns:

True if it is.

Since:

2.3.0

getGenericReturnType

@NonNull
default ClassElement getGenericReturnType()

The generic return type of the method.

Returns:

The return type of the method

Since:

1.1.1

getDescription

@NonNull
default String getDescription(boolean simple)

Get the method description.

Specified by:

getDescription in interface Described

Specified by:

getDescription in interface Element

Parameters:

simple - If simple type names are to be used

Returns:

The method description

overrides

default boolean overrides(@NonNull
                          MethodElement overridden)

Checks if this method element overrides another.

Parameters:

overridden - Possible overridden method

Returns:

true if this overrides passed method element

Since:

3.1

                                 ParameterElement... parameterElements)

Creates a MethodElement for the given parameters.

Parameters:

declaredType - The declaring type

annotationMetadata - The annotation metadata

returnType - The return type

genericReturnType - The generic return type

name - The name

parameterElements - The parameter elements

Returns:

The method element
