Class type SpiderCaml.jsobj

class type jsobj = object .. end

Encapsulation of Javascript values.

Evaluation of Javascript expressions.

method eval : string -> jsobj

Evaluate a Javascript expression in the context of the current object. Raise InvalidType if the value is not an object.

Access to properties.

method get : string -> jsobj

Get the value of a named property. Raise InvalidType if the value is not an object.

method set : string -> jsobj -> unit

Set the value of a named property. Raise InvalidType if the value is not an object.

method get_idx : int -> jsobj

Get the value of a numeric property. Raise InvalidType if the value is not an object.

method set_idx : int -> jsobj -> unit

Set the value of a numeric property. Raise InvalidType if the value is not an object.

Creation of values.

method new_child : ?proto:jsobj ->
       ?active:jsobj active -> unit -> jsobj

Create a new object whose parent is the current object. Raise InvalidType if the value is not an object.

method new_object : ?proto:jsobj ->
       ?active:jsobj active -> unit -> jsobj

Create a new object with no parent. Raise InvalidType if the value is not an object.

method new_object_gen : ?proto:jsobj ->
       ?parent:jsobj ->
       ?active:jsobj active -> unit -> jsobj

Create a new object with a specific parent. Raise InvalidType if the value is not an object.

method lambda : ?name:string ->
       (jsobj -> jsobj array -> jsobj) ->
       jsobj

Create a closure value with an optional name (for decompiling). The first argument of the closure is the global object (not the current one) of the evaluation context. The second argument contains all the arguments passed to the function.

A side effect of calling this method is to register the closure in a global table (of the current runtime). Only a call to destroy_runtime will free this table.

method string : string -> jsobj

method int : int -> jsobj

method bool : bool -> jsobj

method _true : jsobj

method _false : jsobj

method null : jsobj

method void : jsobj

method float : float -> jsobj

method array : jsobj array -> jsobj

Value inspection.

method is_object : bool

method is_bool : bool

method is_int : bool

method is_null : bool

method is_void : bool

method is_string : bool

method is_number : bool

method is_float : bool

method is_array : bool

method get_int : int

Raise InvalidType is the value is not an integer.

method get_bool : bool

Raise InvalidType is the value is not a boolean.

method get_string : string

Raise InvalidType is the value is not a string.

method get_float : float

Raise InvalidType is the value is not a double.

Value conversion.

method to_string : string

method to_object : jsobj

method to_bool : bool

method to_float : float

method to_int : int

Misc.

method destroy_runtime : unit

Free the internal table of all the registered closures. It is possible to use this method on any value of the runtime. After calling it, it is no longer possible to create or to call closures in this runtime.

method new_context : ?active:jsobj active -> unit -> jsobj

Create a new evaluation context with a fresh global object, in the same runtime. Values can be exchanged between contexts of the same runtime.

method version : int

The JS version supported by the current context. Possible values: 100 (JS 1.0), 110 (JS 1.1), 120 (JS 1.2), 130 (JS 1.3), 0 (default), -1 (unknown).

method set_version : int -> unit

Change the JS version supported by the current context. Possible values: 100,110,120,130.
