Method Details

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
default 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

withParameters

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

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

Parameters:

newParameters - The new parameters

Returns:

A new method element

Since:

4.0.0

withNewOwningType

@NonNull
default MethodElement withNewOwningType(@NonNull
 ClassElement owningType)

Returns a new method with a new owning type.

Parameters:

owningType - The owning type.

Returns:

A new method element

Since:

4.0.0

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

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
