    JS_DefineConstDoubles

    Create multiple constant double or integer valued properties on an object.

    Syntax

    bool
    JS_DefineConstDoubles(JSContext *cx, JS::HandleObject obj,
                          const JSConstDoubleSpec *cds);
    
    bool
    JS_DefineConstIntegers(JSContext *cx, JS::HandleObject obj,
                           const JSConstIntegerSpec *cis); // Added in SpiderMonkey 38
    
    Name Type Description
    cx JSContext * The context in which to define the new properties. Requires request. In a JS_THREADSAFE build, the caller must be in a request on this JSContext.
    obj JSObject * Object for which to create new properties.
    cds JSConstDoubleSpec * Pointer to an array of JSConstDoubleSpec records containing property names and values to create. The last array element must contain zero-valued members.
    cis JSConstIntegerSpec * Pointer to an array of JSConstIntegerSpec records containing property names and values to create. The last array element must contain zero-valued members.

    Description

    JS_DefineConstDoubles creates one or more properties for a specified object, obj, where each property consists of a double value.

    JS_DefineConstIntegers creates one or more properties for a specified object, obj, where each property consists of a int32_t value.

    The attributes for each property is set to JSPROP_READONLY | JSPROP_PERMANENT.

    Obsolete from JSAPI 35

    Each property is automatically assigned attributes as specified in the flags field of the JSConstDoubleSpec/JSConstIntegerSpec structure pointed to by cds/cis. If flags is set to 0, the attributes for the property are automatically set to JSPROP_PERMANENT | JSPROP_READONLY.

    cds and cis are pointers to the first element of an array of JSConstDoubleSpec/JSConstIntegerSpec structures. Each array element defines a single property name and property value to create. The name field of the last element of the array must contain 0.

    JS_DefineConstDoubles/JS_DefineConstIntegers create one property for each element in the array what contains a non-zero name field.

    On success, JS_DefineConstDoubles/JS_DefineConstIntegers returns true, indicating it has created all properties listed in the array. Otherwise it returns false.
