JSValue (moe.platform.ios API)

java.lang.Object
- org.moe.natj.general.NativeObject
- - org.moe.natj.objc.ObjCObject
  - - apple.NSObject
    - - apple.javascriptcore.JSValue

All Implemented Interfaces:

NSObject
```
public class JSValue
extends NSObject
```
[@interface]
A JSValue is a reference to a JavaScript value. Every JSValue originates from a JSContext and holds a strong reference to it. When a JSValue instance method creates a new JSValue, the new value originates from the same JSContext.
All JSValues values also originate from a JSVirtualMachine (available indirectly via the context property). It is an error to pass a JSValue to a method or property of a JSValue or JSContext originating from a different JSVirtualMachine. Doing so will raise an Objective-C exception.

    Define properties with custom descriptors on JSValues.
    This method may be used to create a data or accessor property on an object. This method operates in accordance with the Object.defineProperty method in the JavaScript language. Starting with macOS 10.15 and iOS 13, 'property' can be any 'id' and will be converted to a JSValue using the conversion rules of valueWithObject:inContext:. Prior to macOS 10.15 and iOS 13, 'property' was expected to be an NSString *.

    YES if deletion is successful, NO otherwise.
  - hasProperty
```
public boolean hasProperty(java.lang.String property)
```
    Check if a JSValue has a property.
    This method has the same function as the JavaScript operator in.

                                java.lang.String property)
```
    Set a property on a JSValue.
    Corresponds to the JavaScript operation object[property] = value. Starting with macOS 10.15 and iOS 13, 'property' can be any 'id' and will be converted to a JSValue using the conversion rules of valueWithObject:inContext:. Prior to macOS 10.15 and iOS 13, 'property' was expected to be an NSString *.
  - toArray
```
public NSArray<?> toArray()
```
    Convert a JSValue to a NSArray.
    If the value is null or undefined then nil is returned. If the value is not an object then a JavaScript TypeError will be thrown. The property length is read from the object, converted to an unsigned integer, and an NSArray of this size is allocated. Properties corresponding to indicies within the array bounds will be copied to the array, with JSValues converted to equivalent Objective-C objects as specified.
    
    Returns:
    
    The NSArray containing the recursively converted contents of the converted JavaScript array.

  - toDictionary
```
public NSDictionary<?,?> toDictionary()
```
    Convert a JSValue to a NSDictionary.

    The int32_t result of the conversion.
  - toNumber
```
public NSNumber toNumber()
```
    Convert a JSValue to a NSNumber.

    Returns:
    
    The NSNumber result of the conversion.
  - toObject
```
public java.lang.Object toObject()
```
    [@methodgroup] Converting to Objective-C Types
    When converting between JavaScript values and Objective-C objects a copy is performed. Values of types listed below are copied to the corresponding types on conversion in each direction. For NSDictionaries, entries in the dictionary that are keyed by strings are copied onto a JavaScript object. For dictionaries and arrays, conversion is recursive, with the same object conversion being applied to all entries in the collection.
    Returns:
    
    The Objective-C representation of this JSValue.
  - toObjectOfClass

```
    Create a new promise object using the provided executor callback.
    This method is equivalent to calling the Promise constructor in JavaScript. the resolve and reject callbacks each normally take a single value, which they forward to all relevent pending reactions. While inside the executor callback context will act as if it were in any other callback, except calleeFunction will be nil. This also means means the new promise object may be accessed via [context thisValue].
    
    Parameters:
    
    callback - A callback block invoked while the promise object is being initialized. The resolve and reject parameters are functions that can be called to notify any pending reactions about the state of the new promise object.
    
    context - The JSContext to which the resulting JSValue belongs.
    
    Returns:
    
    The JSValue representing a new promise JavaScript object.

```
    Create a new rejected promise object with the provided value.
    This method is equivalent to calling [JSValue valueWithNewPromiseFromExecutor:^(JSValue *resolve, JSValue *reject) { [reject callWithArguments:@[reason]]; } inContext:context]
    
    Parameters:
    
    reason - The result value to be passed to any reactions.

```
    Create a new resolved promise object with the provided value.
    This method is equivalent to calling [JSValue valueWithNewPromiseFromExecutor:^(JSValue *resolve, JSValue *reject) { [resolve callWithArguments:@[result]]; } inContext:context]
    
    Parameters:
    
    result - The result value to be passed to any reactions.
