Public Member Functions | |
bool | add_name (const string &category, const string &name, EggNode *node=NULL) |
Adds the name to the indicated category. | |

Empties the table of used named and prepares the Uniquifier for a new tree. | |
virtual string | filter_name (EggNode *node) |
Returns the name of the given node, or at least the name it should be. | |
virtual TypeHandle | force_init_type () |
virtual string | generate_name (EggNode *node, const string &category, int index) |
Generates a new name for the given node when its existing name clashes with some other node. | |
virtual string | get_category (EggNode *node)=0 |
EggNode * | get_node (const string &category, const string &name) const |
Returns the node associated with the given category and name, or NULL if the name has not been used. | |

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.

bool EggNameUniquifier::add_name | ( | const string & | category, |
const string & | name, | ||
EggNode * | node = NULL |
||
) |
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.
Definition at line 165 of file eggNameUniquifier.cxx.
void EggNameUniquifier::clear | ( | ) |
Empties the table of used named and prepares the Uniquifier for a new tree.
Definition at line 52 of file eggNameUniquifier.cxx.
string EggNameUniquifier::filter_name | ( | EggNode * | node | ) | [virtual] |
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.

string EggNameUniquifier::generate_name | ( | EggNode * | node, |
const string & | category, | ||
int | index | ||
) | [virtual] |
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.

EggNode * EggNameUniquifier::get_node | ( | const string & | category, |
const string & | name | ||
) | const |
Returns the node associated with the given category and name, or NULL if the name has not been used.

bool EggNameUniquifier::has_name | ( | const string & | category, |
const string & | name | ||
) | const |
Returns true if the name has been used for the indicated category already, false otherwise.

static void EggNameUniquifier::init_type | ( | ) | [inline, static] |
This function is declared non-inline to work around a compiler bug in g++ 2.96.
Making it inline seems to cause problems in the optimizer.
