Class AbstractExecutableMethod

java.lang.Object

io.micronaut.context.AbstractExecutableMethod

All Implemented Interfaces:

EnvironmentConfigurable, AnnotationMetadata, AnnotationMetadataDelegate, AnnotationMetadataProvider, AnnotationSource, Executable, ExecutableMethod, MethodReference

@Internal
public abstract class AbstractExecutableMethod
extends Object
implements ExecutableMethod, EnvironmentConfigurable

Abstract base class for generated ExecutableMethod classes to implement. The generated classes should implement the Executable.invoke(Object, Object...) method at compile time providing direct dispatch of the target method

Since:

1.0
