Method Detail

addDynamicConstructor

void addDynamicConstructor(DynamicConstructor constructor)

Adds a dynamic constructor.

Parameters:

constructor - The constructor to add

addDynamicMethodInvocation

void addDynamicMethodInvocation(DynamicMethodInvocation methodInvocation)

Adds a new dynamic method invocation.

Parameters:

methodInvocation -

addStaticMethodInvocation

void addStaticMethodInvocation(StaticMethodInvocation methodInvocation)

Adds a new static method invocation.

Parameters:

methodInvocation -

addDynamicProperty

void addDynamicProperty(DynamicProperty property)

Adds a new dynamic property.

Parameters:

property -

getDynamicProperty

DynamicProperty getDynamicProperty(java.lang.String propertyName)

Retrieves a dynamic property for the specified property name.

Parameters:

propertyName - The name of the property

Returns:

A DynamicProperty instance of null if none exists

getDynamicMethod

DynamicMethodInvocation getDynamicMethod(java.lang.String method_signature)

Retrieves a dynamic method for the specified method name.

Parameters:

method_signature - Then signature of the method

Returns:

The method instance or null if non exists

getProperty

java.lang.Object getProperty(java.lang.Object object,
                             java.lang.String propertyName,
                             InvocationCallback callback)

Attempts to get a dynamic property. If successful the InvocationCallback instance is marked as invoked.

Parameters:

object - The instance

propertyName - The property name to get

callback - The callback object

Returns:

The property value if it exists

setProperty

void setProperty(java.lang.Object object,
                 java.lang.String propertyName,
                 java.lang.Object newValue,
                 InvocationCallback callback)

Attempts to set a dynamic property. If successful the InvocationCallback instance is marked as invoked.

Parameters:

object - The instance

propertyName - The property name to set

callback - The callback object

invokeMethod

java.lang.Object invokeMethod(java.lang.Object object,
                              java.lang.String methodName,

Parameters:

object - The instance to invoke on

methodName - The name of the method

arguments - The arguments of the method

callback - The callback object

Returns:

The method return value

invokeStaticMethod

java.lang.Object invokeStaticMethod(java.lang.Object object,
                                    java.lang.String methodName,
