call's super class function "method()" call's the overridden function "method()" define in this class "native_class_name" You can invoke the super method of a class as follows: var c = java.newClass(native_class_name) Therefore when a method is shadowed by a field, the method can be invoked using java.callMethod. NOTE: In Java a class can have an instance method and instance field with same name.

You can access the instance fields as follows: var if = i.instance_field You can invoke instance methods as follows: var c = java.import('class_name') Īlternatively, the API java.callMethod can be used as follows: java.callMethod(i, 'instance_method',) It has properties that represent the following: The value returned by calling new on the constructor function returned by java.import is a JavaScript object that represents the underlying Java object. When a field is unavailable as a property, then use the API tStaticField or java.getStaticField. When a method is unavailable as a property, then use the API java.callStaticMethod to access the static method. Between the field and method, field gets higher priority. In such case, the inner class gets highest priority. NOTE: It is possible for a Java class to have a static field, a static method, and an inner class with the same name. The value returned when such properties are accessed is again another JavaScript constructor function. When a Java class defines inner classes, these classes can be accessed as properties of the constructor function that java.import returns. tStaticFieldValue('class_name', 'field_name', value)Īccessing inner classes defined by a Java class.

The API tStaticFieldValue can be used to set a static field by passing the class name as the first argument, and the field name as second argument and the value to set as last argument.

java.getStaticFieldValue('class_name', 'field_name')

The API java.getStaticFieldValue can be used to retrieve a static field by passing the class name as the first argument and the field name as the second argument.

c.static_field = 10 Īlternatively, you can use the following APIs: Static fields can be accessed as properties of the constructor function. Static methods can be invoked using the following syntax: var c = java.import('.') Īlternatively, the API java.callStaticMethod can be used as follows: java.callStaticMethod('class_name', 'static_method', ) Static methods can be accessed as properties of the constructor function returned by the API java.import. If the class has overloaded constructor methods, each of them can be called with the keyword " new" by passing the correct parameter types.ĭefining a new method or a new class (which contains new methods) that is not in native, is not supported.Īlternatively, the API java.newInstance can be used to instantiate a Java class by passing the instance name as its first argument and the arguments to the constructor method enclosed in a JavaScript array as the second argument. For example,Įxample 1 var ArrayList = java.import('') Įxample 2 var ArrayList = java.import('') The instances of a Java class can be created with the keyword "new" on the constructor function returned by the API java.import.

Inner classes: Any inner classes that the Java class defines.Īvailable on Android platform.Static methods: Any static methods that the Java class exposes.

Static fields: Any static fields that the Java class exposes.

The constructor function also has properties that map to the following: Returns a JavaScript constructor function that can be used to instantiate the class. Specifies the native class name including the package name that you want to use in JavaScript. JavaScript: java.import (native_class_name) Input Parameters All the APIs, methods, constants, and all members of the native class are directly accessible with the instantiated object. You must use the keyword "new" to instantiate (create an object) an instance of a JavaScript class. This API helps you import any Android native class into JavaScript.

To access a class, use the following API: java.import To use the Native Function APIs in Visualizer Classic, follow these guidelines: Category Android Guidelines for Using Native Function APIs in Quantum Visualizer Classic
