ClassDB¶
Inherits: Object
A class information repository.
描述¶
Provides access to metadata stored for every available class.
Methods¶
Method Descriptions¶
bool can_instantiate ( StringName class ) const
Returns true if objects can be instantiated from the specified class, otherwise returns false.
bool class_exists ( StringName class ) const
Returns whether the specified class is available or not.
PackedStringArray class_get_enum_constants ( StringName class, StringName enum, bool no_inheritance=false ) const
Returns an array with all the keys in enum of class or its ancestry.
PackedStringArray class_get_enum_list ( StringName class, bool no_inheritance=false ) const
Returns an array with all the enums of class or its ancestry.
int class_get_integer_constant ( StringName class, StringName name ) const
Returns the value of the integer constant name of class or its ancestry. Always returns 0 when the constant could not be found.
StringName class_get_integer_constant_enum ( StringName class, StringName name, bool no_inheritance=false ) const
Returns which enum the integer constant name of class or its ancestry belongs to.
PackedStringArray class_get_integer_constant_list ( StringName class, bool no_inheritance=false ) const
Returns an array with the names all the integer constants of class or its ancestry.
Dictionary[] class_get_method_list ( StringName class, bool no_inheritance=false ) const
Returns an array with all the methods of class or its ancestry if no_inheritance is false. Every element of the array is a Dictionary with the following keys: args, default_args, flags, id, name, return: (class_name, hint, hint_string, name, type, usage).
Note: In exported release builds the debug info is not available, so the returned dictionaries will contain only method names.
Variant class_get_property ( Object object, StringName property ) const
Returns the value of property of object or its ancestry.
Dictionary[] class_get_property_list ( StringName class, bool no_inheritance=false ) const
Returns an array with all the properties of class or its ancestry if no_inheritance is false.
Dictionary class_get_signal ( StringName class, StringName signal ) const
Returns the signal data of class or its ancestry. The returned value is a Dictionary with the following keys: args, default_args, flags, id, name, return: (class_name, hint, hint_string, name, type, usage).
Dictionary[] class_get_signal_list ( StringName class, bool no_inheritance=false ) const
Returns an array with all the signals of class or its ancestry if no_inheritance is false. Every element of the array is a Dictionary as described in class_get_signal.
bool class_has_enum ( StringName class, StringName name, bool no_inheritance=false ) const
Returns whether class or its ancestry has an enum called name or not.
bool class_has_integer_constant ( StringName class, StringName name ) const
Returns whether class or its ancestry has an integer constant called name or not.
bool class_has_method ( StringName class, StringName method, bool no_inheritance=false ) const
Returns whether class (or its ancestry if no_inheritance is false) has a method called method or not.
bool class_has_signal ( StringName class, StringName signal ) const
Returns whether class or its ancestry has a signal called signal or not.
Error class_set_property ( Object object, StringName property, Variant value ) const
Sets property value of object to value.
PackedStringArray get_class_list ( ) const
Returns the names of all the classes available.
PackedStringArray get_inheriters_from_class ( StringName class ) const
Returns the names of all the classes that directly or indirectly inherit from class.
StringName get_parent_class ( StringName class ) const
Returns the parent class of class.
Variant instantiate ( StringName class ) const
Creates an instance of class.
bool is_class_enabled ( StringName class ) const
Returns whether this class is enabled or not.
bool is_parent_class ( StringName class, StringName inherits ) const
Returns whether inherits is an ancestor of class or not.
