MetaMethod (Groovy 5.0.0-SNAPSHOT)

groovy.lang.MetaMethod

All Implemented Interfaces and Traits:

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

    Parameters:
    pt - A list of parameters types
- Method Detail
  - @Deprecated
    public void checkParameters(Class[] arguments)
    
    Checks that the given parameters are valid to call this method.
    throws:
    IllegalArgumentException if the parameters are not valid
    deprecated:
    
    Parameters:
    arguments - the arguments to check
  - @Override
    public Object clone()
  - public Object doMethodInvoke(Object object, Object[] arguments)
    
    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.
    arguments - 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 abstract CachedClass getDeclaringClass()
    
    Gets the class where this method is declared.
    Returns:
    class of this method
  - public String getDescriptor()
    
    Returns a descriptor of this method based on the return type and parameters of this method.
  - public abstract int getModifiers()
    
    Returns the modifiers of this method.
    Returns:
    modifiers as an int.
  - public String getMopName()
  - public abstract String getName()
    
    Returns the name of this method.
    Returns:
    name of this method
  - public abstract Class getReturnType()
    
    Returns 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 abstract Object invoke(Object object, Object[] arguments)
    
    Invokes 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 this method is abstract.
    Returns:
    true if this method is abstract
  - public boolean isCacheable()
    
    Returns whether this object is cacheable.
  - public boolean isDefault()
    
    Returns whether this method is interface-default.
    Returns:
    true if this method is default
  - public boolean isMethod(MetaMethod method)
    
    Returns true if 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 isSame(MetaMethod method)
    
    Determines if the given method has the same name, parameters, return type and modifiers but may be defined on another type.
    Parameters:
    method - the method to compare against
  - public final RuntimeException processDoMethodInvokeException(Exception e, Object object, Object[] arguments)
    
    Called when an exception occurs while invoking this method.
