Method Detail

construct

public V8Value construct(V8Value target,
                         V8ValueArray arguments,
                         V8Value newTarget)
                  throws JavetException

Description copied from interface: IJavetProxyHandler

handler.construct() The handler.construct() method is a trap for the [[Construct]] object internal method, which is used by operations such as the new operator. In order for the new operation to be valid on the resulting Proxy object, the target used to initialize the proxy must itself be a valid constructor.

Parameters:

target - the target

arguments - the arguments

newTarget - the new target

Returns:

the V8 value

Throws:

JavetException - the javet exception

getCallbackContexts

public JavetCallbackContext[] getCallbackContexts()

Description copied from interface: IJavetDirectCallable

Get supported callback contexts.

Returns:

the supported callback contexts

getProxyMode

public V8ProxyMode getProxyMode()

Description copied from class: BaseJavetReflectionProxyHandler

Gets proxy mode.

Specified by:

getProxyMode in class BaseJavetReflectionProxyHandler<T extends java.lang.Class<?>,E extends java.lang.Exception>

Returns:

the proxy mode

has

public V8ValueBoolean has(V8Value target,
                          V8Value property)
                   throws JavetException

Description copied from interface: IJavetProxyHandler

handler.has() The handler.has() method is a trap for the [[HasProperty]] object internal method, which is used by operations such as the in operator.

Parameters:

target - the target

property - the property

Returns:

the V8 value boolean

Throws:

JavetException - the javet exception

initialize

protected void initialize()

Description copied from class: BaseJavetReflectionProxyHandler

Initialize.

Specified by:

initialize in class BaseJavetReflectionProxyHandler<T extends java.lang.Class<?>,E extends java.lang.Exception>

initializeFieldsAndMethods

protected void initializeFieldsAndMethods(java.lang.Class<?> currentClass,
                                          boolean staticMode)

Initialize fields and methods.

Parameters:

currentClass - the current class

staticMode - the static mode

Since:

0.9.6

internalGet

protected V8Value internalGet(V8Value target,
                              V8Value property)
                       throws JavetException,
                              E extends java.lang.Exception

Description copied from class: BaseJavetReflectionProxyHandler

Internal get.

Specified by:
