Method Detail

invoke

public NativeInvocation invoke(String methodName,
                               InvocationArg... arg)

Description copied from interface: NativeInvocation

Invokes a method of the instance of the class that is set for this NativeInvocation

Specified by:

invoke in interface NativeInvocation<T>

Parameters:

methodName - The method name

arg - The arguments to use for invoking the method

Returns:

A NativeInvocation instance containing the result of the invocation

invokeStatic

public NativeInvocation invokeStatic(String methodName,
                                     InvocationArg... arg)

Description copied from interface: NativeInvocation

Invokes a static method of the class that is set for this NativeInvocation

Specified by:

invokeStatic in interface NativeInvocation<T>

Parameters:

methodName - The static method name

arg - The arguments to use for invoking the static method

Returns:

A NativeInvocation instance containing the result of the invocation

invokeAsync

public void invokeAsync(long functionPointer,
                        String methodName,
                        InvocationArg... args)

Description copied from interface: NativeInvocation

Invokes asynchronously a method of the instance of the class that is set for this NativeInvocation. The result of the invocation should be provided later using the performCallback method of a NativeCallbackSupport class. Any possible returned objects from the actual synchronous invocation of the defined method will be dropped.

Specified by:

invokeAsync in interface NativeInvocation<T>

Parameters:

functionPointer - The address of the function pointer that will be used later in the native side in order to actually paerform the callback.

methodName - The method name

args - The arguments to use when invoking the callback method (the functionPointer)

invokeToChannel

public void invokeToChannel(long channelAddress,
                            String methodName,
                            InvocationArg... args)

Description copied from interface: NativeInvocation

Invokes a method of the instance of the class that is set for this NativeInvocation. The result of the invocation should be provided later using the doCallback method of a NativeCallbackToRustChannelSupport class. Any possible returned objects from the actual synchronous invocation of the defined method will be dropped.

Specified by:

invokeToChannel in interface NativeInvocation<T>

Parameters:

channelAddress - The memory address of the channel

methodName - The method name

args - The arguments

initializeCallbackChannel

public void initializeCallbackChannel(long channelAddress)

Description copied from interface: NativeInvocation

Initialize a callback channel for this NativeInvocation. The channel can be used by Java to send values to Rust using the doCallback method of a NativeCallbackToRustChannelSupport class.

Specified by:

initializeCallbackChannel in interface NativeInvocation<T>

Parameters:

channelAddress - The memory address of the channel

field

public NativeInvocation field(String methodName)

Description copied from interface: NativeInvocation

Retrieves the instance held under the Field fieldName

Specified by:

field in interface NativeInvocation<T>

Parameters:

methodName - The name of the field to retrieve

Returns:

A NativeInvocation instance containing the defined field.

getObject

public T getObject()

Specified by:

getObject in interface ObjectValue

getObjectClass

public Class<?> getObjectClass()

Specified by:

getObjectClass in interface ObjectValue

getJson

public String getJson()

Specified by:

getJson in interface JsonValue
