Class MethodOverride

    • org.springframework.beans.factory.support.MethodOverride
  • All Implemented Interfaces:
    BeanMetadataElement
    Direct Known Subclasses:
    LookupOverride, ReplaceOverride


    public abstract class MethodOverride
    extends java.lang.Object
    implements BeanMetadataElement
    Object representing the override of a method on a managed object by the IoC container.

    Note that the override mechanism is not intended as a generic means of inserting crosscutting code: use AOP for that.

      All Methods Instance Methods Abstract Methods Concrete Methods 
      Modifier and Type Method and Description
      boolean equals(java.lang.Object other) 
      java.lang.String getMethodName()
      Return the name of the method to be overridden.
      java.lang.Object getSource()
      Return the configuration source Object for this metadata element (may be null).
      int hashCode() 
      protected boolean isOverloaded()
      Return whether the overridden method is overloaded (i.e., whether argument type matching needs to occur to disambiguate methods of the same name).
      abstract boolean matches(java.lang.reflect.Method method)
      Subclasses must override this to indicate whether they match the given method.
      protected void setOverloaded(boolean overloaded)
      Set whether the overridden method is overloaded (i.e., whether argument type matching needs to occur to disambiguate methods of the same name).
      void setSource(java.lang.Object source)
      Set the configuration source Object for this metadata element.

      • MethodOverride

        protected MethodOverride(java.lang.String methodName)
        Construct a new override for the given method.
        Parameters:
        methodName - the name of the method to override
    • Method Detail

      • getMethodName

        public java.lang.String getMethodName()
        Return the name of the method to be overridden.
      • setOverloaded

        protected void setOverloaded(boolean overloaded)
        Set whether the overridden method is overloaded (i.e., whether argument type matching needs to occur to disambiguate methods of the same name).

        Default is true; can be switched to false to optimize runtime performance.

      • isOverloaded

        protected boolean isOverloaded()
        Return whether the overridden method is overloaded (i.e., whether argument type matching needs to occur to disambiguate methods of the same name).
      • setSource

        public void setSource(@Nullable
                              java.lang.Object source)
        Set the configuration source Object for this metadata element.

        The exact type of the object will depend on the configuration mechanism used.

      • matches

        public abstract boolean matches(java.lang.reflect.Method method)
        Subclasses must override this to indicate whether they match the given method. This allows for argument list checking as well as method name checking.
        Parameters:
        method - the method to check
        Returns:
        whether this override matches the given method
      • equals

        public boolean equals(java.lang.Object other)
        Overrides:
        equals in class java.lang.Object
      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class java.lang.Object
