A class information repository. Provides access to metadata stored for every available class. Returns [code]true[/code] if objects can be instantiated from the specified [param class], otherwise returns [code]false[/code]. Returns whether the specified [param class] is available or not. Returns an array with all the keys in [param enum] of [param class] or its ancestry. Returns an array with all the enums of [param class] or its ancestry. Returns the value of the integer constant [param name] of [param class] or its ancestry. Always returns 0 when the constant could not be found. Returns which enum the integer constant [param name] of [param class] or its ancestry belongs to. Returns an array with the names all the integer constants of [param class] or its ancestry. Returns the number of arguments of the method [param method] of [param class] or its ancestry if [param no_inheritance] is [code]false[/code]. Returns an array with all the methods of [param class] or its ancestry if [param no_inheritance] is [code]false[/code]. Every element of the array is a [Dictionary] with the following keys: [code]args[/code], [code]default_args[/code], [code]flags[/code], [code]id[/code], [code]name[/code], [code]return: (class_name, hint, hint_string, name, type, usage)[/code]. [b]Note:[/b] In exported release builds the debug info is not available, so the returned dictionaries will contain only method names. Returns the value of [param property] of [param object] or its ancestry. Returns the default value of [param property] of [param class] or its ancestor classes. Returns the getter method name of [param property] of [param class]. Returns an array with all the properties of [param class] or its ancestry if [param no_inheritance] is [code]false[/code]. Returns the setter method name of [param property] of [param class]. Returns the [param signal] data of [param class] or its ancestry. The returned value is a [Dictionary] with the following keys: [code]args[/code], [code]default_args[/code], [code]flags[/code], [code]id[/code], [code]name[/code], [code]return: (class_name, hint, hint_string, name, type, usage)[/code]. Returns an array with all the signals of [param class] or its ancestry if [param no_inheritance] is [code]false[/code]. Every element of the array is a [Dictionary] as described in [method class_get_signal]. Returns whether [param class] or its ancestry has an enum called [param name] or not. Returns whether [param class] or its ancestry has an integer constant called [param name] or not. Returns whether [param class] (or its ancestry if [param no_inheritance] is [code]false[/code]) has a method called [param method] or not. Returns whether [param class] or its ancestry has a signal called [param signal] or not. Sets [param property] value of [param object] to [param value]. Returns the names of all the classes available. Returns the names of all the classes that directly or indirectly inherit from [param class]. Returns the parent class of [param class]. Creates an instance of [param class]. Returns whether this [param class] is enabled or not. Returns whether [param class] (or its ancestor classes if [param no_inheritance] is [code]false[/code]) has an enum called [param enum] that is a bitfield. Returns whether [param inherits] is an ancestor of [param class] or not.
