public void addMetaBeanProperty(MetaBeanProperty metaBeanProperty)

Overrides groovy.lang.DelegatingMetaClass.addMetaBeanProperty.

Implements groovy.lang.MutableMetaClass.addMetaBeanProperty.

Doc from groovy.lang.MutableMetaClass.addMetaBeanProperty.

Adds a new MetaBeanProperty to the MetaClass

Parameters
metaBeanProperty:MetaBeanProperty

The MetaBeanProperty instance

addMetaMethodback to summary
public void addMetaMethod(MetaMethod metaMethod)

Overrides groovy.lang.DelegatingMetaClass.addMetaMethod.

Implements groovy.lang.MutableMetaClass.addMetaMethod.

Doc from groovy.lang.MutableMetaClass.addMetaMethod.

Adds a new MetaMethod to the MetaClass

Parameters
metaMethod:MetaMethod

The MetaMethod to add

addNewInstanceMethodback to summary
public void addNewInstanceMethod(Method method)

Overrides groovy.lang.DelegatingMetaClass.addNewInstanceMethod.

Implements groovy.lang.MutableMetaClass.addNewInstanceMethod.

Doc from groovy.lang.MutableMetaClass.addNewInstanceMethod.

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.

Parameters
method:Method

the method to be added

addNewStaticMethodback to summary
public void addNewStaticMethod(Method method)

Overrides groovy.lang.DelegatingMetaClass.addNewStaticMethod.

Implements groovy.lang.MutableMetaClass.addNewStaticMethod.

Doc from groovy.lang.MutableMetaClass.addNewStaticMethod.

adds a new static method to this MetaClass. This is only possible as long as initialise was not called.

Parameters
method:Method

the method to be added

equalsback to summary
public boolean equals(Object obj)

Overrides groovy.lang.DelegatingMetaClass.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
obj:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

getPropertyback to summary
public Object getProperty(String property)

Overrides groovy.lang.DelegatingMetaClass.getProperty.

Overrides default groovy.lang.GroovyObject.getProperty.

Doc from groovy.lang.GroovyObject.getProperty.

Retrieves a property value.

Parameters
property:String

the name of the property of interest

Returns:Object

the given property

initializeback to summary
public void initialize()

Overrides groovy.lang.DelegatingMetaClass.initialize.

Implements groovy.lang.MetaClass.initialize.

Doc from groovy.lang.MetaClass.initialize.

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.

invokeMethodback to summary
public Object invokeMethod(String name, Object args)

Overrides groovy.lang.DelegatingMetaClass.invokeMethod.

Overrides default groovy.lang.GroovyObject.invokeMethod.

Doc from groovy.lang.GroovyObject.invokeMethod.

Invokes the given method.

Parameters
name:String

the name of the method to call

args:Object

the arguments to use for the method call

Returns:Object

the result of invoking the method

setPropertyback to summary
public void setProperty(String property, Object newValue)

Overrides groovy.lang.DelegatingMetaClass.setProperty.

Overrides default groovy.lang.GroovyObject.setProperty.

Doc from groovy.lang.GroovyObject.setProperty.

Sets the given property to the new value.

Parameters
property:String

the name of the property of interest

newValue:Object

the new value for the property
