Public Member Functions | |
bool | addName (string category, string name, EggNode node) |
Adds the name to the indicated category. | |
bool | addName (string category, string name) |
Adds the name to the indicated category. | |
clear () | |
Empties the table of used named and prepares the Uniquifier for a new tree. | |
clearUserData (TypeHandle type) | |
Removes the user data pointer of the indicated type. | |
clearUserData () | |
Removes *all* user data pointers from the node. | |
string | filterName (EggNode node) |
Returns the name of the given node, or at least the name it should be. | |
string | generateName (EggNode node, string category, int index) |
Generates a new name for the given node when its existing name clashes with some other node. | |
string | getCategory (EggNode node) |
EggNode | getNode (string category, string name) |
Returns the node associated with the given category and name, or NULL if the name has not been used. | |
EggUserData | getUserData (TypeHandle type) |
Returns the user data pointer of the indicated type, if it exists, or NULL if it does not. | |
EggUserData | getUserData () |
Returns the user data pointer most recently stored on this object, or NULL if nothing was previously stored. | |
bool | hasName (string category, string name) |
Returns true if the name has been used for the indicated category already, false otherwise. | |
bool | hasUserData () |
Returns true if a generic user data pointer has recently been set and not yet cleared, false otherwise. | |
bool | hasUserData (TypeHandle type) |
Returns true if the user data pointer of the indicated type has been set, false otherwise. | |
setUserData (EggUserData user_data) | |
Sets the user data associated with this object. | |
uniquify (EggNode node) | |
Begins the traversal from the indicated node. | |

This is a handy class for guaranteeing unique node names in an egg hierarchy.
It is an abstract class; to use it you must subclass off of it. See the comment above.
Adds the name to the indicated category.
This name will not be used for any other egg node within this category. Returns true if the name was added, or false if it was already in use for the category.
Adds the name to the indicated category.
This name will not be used for any other egg node within this category. Returns true if the name was added, or false if it was already in use for the category.
clear | ( | ) |
Empties the table of used named and prepares the Uniquifier for a new tree.
clearUserData | ( | ) | [inherited] |
Removes *all* user data pointers from the node.
clearUserData | ( | TypeHandle | type | ) | [inherited] |
Removes the user data pointer of the indicated type.
Returns the name of the given node, or at least the name it should be.
This provides a hook to adjust the name before attempting to uniquify it, if desired, for instance to remove invalid characters.
Generates a new name for the given node when its existing name clashes with some other node.
This function will be called repeatedly, if necessary, until it returns a name that actually is unique.
The category is the string returned by get_category(), and index is a uniquely-generated number that may be useful for synthesizing the name.
static TypeHandle getClassType | ( | ) | [static] |
Reimplemented from EggObject.
Reimplemented in EggGroupUniquifier, and EggPoolUniquifier.
Returns the node associated with the given category and name, or NULL if the name has not been used.
EggUserData getUserData | ( | ) | [inherited] |
Returns the user data pointer most recently stored on this object, or NULL if nothing was previously stored.
EggUserData getUserData | ( | TypeHandle | type | ) | [inherited] |
Returns the user data pointer of the indicated type, if it exists, or NULL if it does not.
Returns true if the name has been used for the indicated category already, false otherwise.
bool hasUserData | ( | ) | [inherited] |
Returns true if a generic user data pointer has recently been set and not yet cleared, false otherwise.
bool hasUserData | ( | TypeHandle | type | ) | [inherited] |
Returns true if the user data pointer of the indicated type has been set, false otherwise.
setUserData | ( | EggUserData | user_data | ) | [inherited] |
Sets the user data associated with this object.
This may be any EggUserData-derived object. The egg library will do nothing with this pointer, except to hold its reference count and return the pointer on request.
The EggObject maintains multiple different EggUserData pointers, one for each unique type (as reported by get_type()). If you know that only one type of EggUserData object will be added in your application, you may use the query functions that accept no parameters, but it is recommended that in general you pass in the type of your particular user data, to allow multiple applications to coexist in the same egg data.
This pointer is also copied by the copy assignment operator and copy constructor.
uniquify | ( | EggNode | node | ) |
Begins the traversal from the indicated node.
