Class MethodOverride

org.springframework.beans.factory.support.MethodOverride

All Implemented Interfaces:

BeanMetadataElement

Direct Known Subclasses:

LookupOverride, ReplaceOverride

public abstract class MethodOverride
extends 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.

Since:

1.1

Constructor Detail

MethodOverride

protected MethodOverride(String methodName)

Construct a new override for the given method.

Parameters:

methodName - the name of the method to override

Method Detail

getMethodName

public 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(Object source)

Set the configuration source Object for this metadata element.

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

getSource

public Object getSource()

Description copied from interface: BeanMetadataElement

Return the configuration source Object for this metadata element (may be null).

Specified by:

getSource in interface BeanMetadataElement

matches

public abstract boolean matches(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(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
