MetaMethod (groovy 3.0.4 API)

groovy.lang.MetaMethod

All Implemented Interfaces and Traits:

Cloneable
```
public abstract class MetaMethod
extends ParameterTypes
implements Cloneable
```
Represents a Method on a Java object a little like Method except without using reflection to invoke the method

    Constructor wit a list of parameter classes
    Parameters:
    pt - A list of parameters types
- Method Detail
  - public void checkParameters(Class[] arguments)
    
    Checks that the given parameters are valid to call this method
    throws:
    IllegalArgumentException if the parameters are not valid
    
    Parameters:
    arguments - the arguments to check
  - public Object clone()
  - public Object doMethodInvoke(Object object, Object[] argumentArray)
    
    Invokes the method this object represents. This method is not final but it should be overloaded very carefully and only by generated methods there is no guarantee that it will be called
    Parameters:
    object - The object the method is to be called at.
    argumentArray - Arguments for the method invocation.
    Returns:
    The return value of the invoked method.
  - protected static boolean equal(CachedClass[] a, Class[] b)
  - protected static boolean equal(CachedClass[] a, CachedClass[] b)
  - public CachedClass getDeclaringClass()
    
    Gets the class where this method is declared
    Returns:
    class of this method
  - public String getDescriptor()
    
    Return a descriptor of this method based on the return type and parameters of this method.
  - public int getModifiers()
    
    Returns the modifiers for this method
    Returns:
    modifiers as an int.
  - public String getMopName()
  - public String getName()
    
    Returns the name of the method represented by this class
    Returns:
    name of this method
  - public Class getReturnType()
    
    Access the return type for this method
    Returns:
    the return type of this method
  - public String getSignature()
    
    Returns the signature of this method
    Returns:
    The signature of this method
  - public Object invoke(Object object, Object[] arguments)
    
    Invoke this method
    Parameters:
    object - The object this method should be invoked on
    arguments - The arguments for the method if applicable
    Returns:
    The return value of the invocation
  - public boolean isAbstract()
    
    Returns whether or not this method is abstract.
    Returns:
    true if this method is abstract
  - public boolean isCacheable()
    
    Returns whether this object is cacheable
  - public boolean isMethod(MetaMethod method)
    
    Returns true if this this metamethod represents the same method as the argument.
    Parameters:
    method - A metaMethod instance
    Returns:
    true if method is for the same method as this method, false otherwise.
  - public final boolean isPrivate()
    
    Returns whether or not this method is private.
    Returns:
    true if this method is private
  - public final boolean isProtected()
    
    Returns whether or not this method is protected.
    Returns:
    true if this method is protected
  - public final boolean isPublic()
    
    Returns whether or not this method is public.
    Returns:
    true if this method is public

    Parameters:
    method - the method to compare against
    Returns:
    true if the given method has the same name, parameters, return type and modifiers but may be defined on another type

    Returns whether or not this method is static.
    Returns:
    true if this method is static
  - public final RuntimeException processDoMethodInvokeException(Exception e, Object object, Object[] argumentArray)
