Nested Class Summary

Nested classes
Modifiers	Name	Description
`static @interface`	`Traits.Implemented`	Internal annotation used to indicate which methods in a trait interface have a default implementation.
`static @interface`	`Traits.TraitBridge`	Internal annotation used to indicate that a method is a bridge method to a trait default implementation.

Methods Summary

Methods
Type	Name and description
`static Method`	`getBridgeMethodTarget(Method someMethod)` Reflection API to find the method corresponding to the default implementation of a trait, given a bridge method.
`static boolean`	`hasDefaultImplementation(MethodNode method)` Indicates whether a method in a trait interface has a default implementation.
`static boolean`	`isAnnotatedWithTrait(ClassNode cNode)` Returns true if the specified class node is annotated with the Trait interface.
`static boolean`	`isBridgeMethod(Method someMethod)` Reflection API to indicate whether some method is a bridge method to the default implementation of a trait.
`static boolean`	`isForceOverride(MethodNode methodNode)` Returns true if the specified method node is annotated with ForceOverride
`static boolean`	`isForceOverride(Method methodNode)` Returns true if the specified method is annotated with ForceOverride
`static boolean`	`isTrait(ClassNode cNode)` Returns true if the specified class node is a trait.
`static boolean`	`isTrait(Class clazz)` Returns true if the specified class is a trait.

- Method Detail
  - public static Method getBridgeMethodTarget(Method someMethod)
    
    Reflection API to find the method corresponding to the default implementation of a trait, given a bridge method.
    Parameters:
    someMethod - a method node
    Returns:
    null if it is not a method implemented in a trait. If it is, returns the method from the trait class.
  - public static boolean hasDefaultImplementation(MethodNode method)
    
    Indicates whether a method in a trait interface has a default implementation.
    Parameters:
    method - a method node
    Returns:
    true if the method has a default implementation in the trait
  - public static boolean isAnnotatedWithTrait(ClassNode cNode)
    
    Returns true if the specified class node is annotated with the Trait interface.
    Parameters:
    cNode - a class node
    Returns:
    true if the specified class node is annotated with the Trait interface.
  - public static boolean isBridgeMethod(Method someMethod)
    
    Reflection API to indicate whether some method is a bridge method to the default implementation of a trait.
    Parameters:
    someMethod - a method node
    Returns:
    null if it is not a method implemented in a trait. If it is, returns the method from the trait class.
  - public static boolean isForceOverride(MethodNode methodNode)
    
    Returns true if the specified method node is annotated with ForceOverride
    Parameters:
    methodNode - a method node
    Returns:
    true if the specified method node is annotated with ForceOverride
  - public static boolean isForceOverride(Method methodNode)
    
    Returns true if the specified method is annotated with ForceOverride
    Parameters:
    methodNode - a method
    Returns:
    true if the specified method is annotated with ForceOverride
  - public static boolean isTrait(ClassNode cNode)
    
    Returns true if the specified class node is a trait.
    Parameters:
    cNode - a class node to test
    Returns:
    true if the classnode represents a trait
  - public static boolean isTrait(Class clazz)
    
    Returns true if the specified class is a trait.
    Parameters:
    clazz - a class to test
    Returns:
    true if the classnode represents a trait
