Task with a main method to be implemented by subclasses

This class is provided for compatibility between different parallelization systems. It can be used to run a fragment of code on a different thread and to register a reaction to UI events.

Introduced properties

fun gdk_main: Bool

core :: Task :: gdk_main

Small unit of code executed by the GDK loop when idle
fun main

core :: Task :: main

Main method of this task

Redefined properties

redef type SELF: Task

core $ Task :: SELF

Type of this instance, automatically specialized in every class

All properties

fun !=(other: nullable Object): Bool

core :: Object :: !=

Have self and other different values?
fun ==(other: nullable Object): Bool

core :: Object :: ==

Have self and other the same value?
type CLASS: Class[SELF]

core :: Object :: CLASS

protected fun class_factory(name: String): CLASS

core :: Object :: class_factory

Implementation used by get_class to create the specific class.
fun class_name: String

core :: Object :: class_name

The class name of the object.
fun gdk_main: Bool

core :: Task :: gdk_main

Small unit of code executed by the GDK loop when idle
fun get_class: CLASS

core :: Object :: get_class

The meta-object representing the dynamic type of self.
fun hash: Int

core :: Object :: hash

The hash code of the object.
init init

core :: Object :: init

fun inspect: String

core :: Object :: inspect

Developer readable representation of self.
protected fun inspect_head: String

core :: Object :: inspect_head

Return "CLASSNAME:#OBJECTID".
intern fun is_same_instance(other: nullable Object): Bool

core :: Object :: is_same_instance

Return true if self and other are the same instance (i.e. same identity).
fun is_same_serialized(other: nullable Object): Bool

core :: Object :: is_same_serialized

Is self the same as other in a serialization context?
intern fun is_same_type(other: Object): Bool

core :: Object :: is_same_type

Return true if self and other have the same dynamic type.
fun main

core :: Task :: main

Main method of this task
intern fun object_id: Int

core :: Object :: object_id

An internal hash code for the object based on its identity.
fun output

core :: Object :: output

Display self on stdout (debug only).
intern fun output_class_name

core :: Object :: output_class_name

Display class name on stdout (debug only).
fun serialization_hash: Int

core :: Object :: serialization_hash

Hash value use for serialization
intern fun sys: Sys

core :: Object :: sys

Return the global sys object, the only instance of the Sys class.
abstract fun to_jvalue(env: JniEnv): JValue

core :: Object :: to_jvalue

fun to_s: String

core :: Object :: to_s

nitcorn :: RestfulTask

Thread dedicated to a single request

Descendants

class HWTask

pthreads :: HWTask

Task printing "hello world" on standard output
