JavaScriptCore – 6.0

A JSSClass represents a custom JavaScript class registered by the user in a JSCContext. It allows to create new JavaScripts objects whose instances are created by the user using this API. It’s possible to add constructors, properties and methods for a JSSClass by providing GCallbacks to implement them.

JSCContext represents a JavaScript execution context, where all operations take place and where the values will be associated.

JSCException represents a JavaScript exception.

JSCValue represents a reference to a value in a JSCContext. The JSCValue protects the referenced value from being garbage collected.

JSCVirtualMachine represents a group of JSCContexts. It allows concurrent JavaScript execution by creating a different instance of JSCVirtualMachine in each thread.

JSCWeakValue represents a weak reference to a value in a JSCContext. It can be used to keep a reference to a JavaScript value without protecting it from being garbage collected and without referencing the JSCContext either.

Virtual table for a JSCClass. This can be optionally used when registering a JSCClass in a JSCContext to provide a custom implementation for the class. All virtual functions are optional and can be set to NULL to fallback to the default implementation.

Enum values to specify a mode to check for syntax errors in jsc_context_check_syntax().

Enum values to specify the result of jsc_context_check_syntax().

Enum values for options types.

Possible types of the elements contained in a typed array.

since: 2.38

Flags used when defining properties with jsc_value_object_define_property_data() and jsc_value_object_define_property_accessor().

The type of delete_property in JSCClassVTable. This is only required when you need to handle external properties not added to the prototype.

The type of enumerate_properties in JSCClassVTable. This is only required when you need to handle external properties not added to the prototype.

The type of get_property in JSCClassVTable. This is only required when you need to handle external properties not added to the prototype.

The type of has_property in JSCClassVTable. This is only required when you need to handle external properties not added to the prototype.

The type of set_property in JSCClassVTable. This is only required when you need to handle external properties not added to the prototype.

Function used to handle JavaScript exceptions in a JSCContext.

A function passed to jsc_value_new_promise called during initialization.

unstable since: 2.48

Function used to iterate options.

since: 2.24

Returns the major version number of the JavaScriptCore library. (e.g. in JavaScriptCore version 1.8.3 this is 1.)

Returns the micro version number of the JavaScriptCore library. (e.g. in JavaScriptCore version 1.8.3 this is 3.)

Returns the minor version number of the JavaScriptCore library. (e.g. in JavaScriptCore version 1.8.3 this is 8.)

Iterates all available options calling function for each one. Iteration can stop early if function returns FALSE.

Get option as a #gboolean value.

since: 2.24

Get option as a #gdouble value.

since: 2.24

Get option as a #gint value.

since: 2.24

Create a GOptionGroup to handle JSCOptions as command line arguments. The options will be exposed as command line arguments with the form —jsc-<option>=<value>. Each entry in the returned GOptionGroup is configured to apply the corresponding option during command line parsing. Applications only need to pass the returned group to g_option_context_add_group(), and the rest will be taken care for automatically.

since: 2.24

Get option as a range string. The string must be in the format [!]<low>[:<high>] where low and high are #guint values. Values between low and high (both included) will be considered in the range, unless ! is used to invert the range.

since: 2.24

Get option as a #gsize value.

Get option as a #guint value.

Check the version of JSC header files at compile time.

Like jsc_get_major_version(), but from the headers used at application compile time, rather than from the library linked against at application run time.

Like jsc_get_micro_version(), but from the headers used at application compile time, rather than from the library linked against at application run time.

Like jsc_get_minor_version(), but from the headers used at application compile time, rather than from the library linked against at application run time.

Allows the DFG JIT to be used if TRUE. Option type: JSC_OPTION_BOOLEAN Default value: TRUE.

Allows the FTL JIT to be used if TRUE. Option type: JSC_OPTION_BOOLEAN Default value: TRUE.

Allows the executable pages to be allocated for JIT and thunks if TRUE. Option type: JSC_OPTION_BOOLEAN Default value: TRUE.

Allows the LLINT to be used if TRUE. Option type: JSC_OPTION_BOOLEAN Default value: TRUE.
