Method Detail

initialize

public void initialize()

Description copied from interface: MetaClass

complete the initialisation process. After this method is called no methods should be added to the meta class. Invocation of methods or access to fields/properties is forbidden unless this method is called. This method should contain any initialisation code, taking a longer time to complete. An example is the creation of the Reflector. It is suggested to synchronize this method.

Specified by:

initialize in interface MetaClass

Overrides:

initialize in class DelegatingMetaClass

replaceDelegate

public GroovyObject replaceDelegate()

invokeMethod

public Object invokeMethod(String name,
                  Object args)

Description copied from interface: GroovyObject

Invokes the given method.

Specified by:

invokeMethod in interface GroovyObject

Overrides:

invokeMethod in class DelegatingMetaClass

Parameters:

name - the name of the method to call

args - the arguments to use for the method call

Returns:

the result of invoking the method

getProperty

public Object getProperty(String property)

Description copied from interface: GroovyObject

Retrieves a property value.

Specified by:

Parameters:

property - the name of the property of interest

Returns:

the given property

setProperty

public void setProperty(String property,
               Object newValue)

Description copied from interface: GroovyObject

Parameters:

property - the name of the property of interest

newValue - the new value for the property

addNewInstanceMethod

public void addNewInstanceMethod(Method method)

Description copied from interface: MutableMetaClass

adds a new instance method to this MetaClass. Instance methods are able to overwrite the original methods of the class. Calling this method should not be done after initialise was called.

Specified by:

addNewInstanceMethod in interface MutableMetaClass

Overrides:

addNewInstanceMethod in class DelegatingMetaClass

Parameters:

method - the method to be added

addNewStaticMethod

public void addNewStaticMethod(Method method)

Description copied from interface: MutableMetaClass

Overrides:

addNewStaticMethod in class DelegatingMetaClass

Parameters:

method - the method to be added

addMetaMethod

public void addMetaMethod(MetaMethod metaMethod)

Parameters:

metaMethod - The MetaMethod to add

addMetaBeanProperty

public void addMetaBeanProperty(MetaBeanProperty metaBeanProperty)

Description copied from interface: MutableMetaClass
