Public Member Functions | |
| bool | operator== (const xiiTagSetTemplate &other) const |
| void | Set (const xiiTag &tag) |
| Adds the given tag to the set. | |
| void | Remove (const xiiTag &tag) |
| Removes the given tag. | |
| bool | IsSet (const xiiTag &tag) const |
| Returns true, if the given tag is in the set. | |
| bool | IsAnySet (const xiiTagSetTemplate &otherSet) const |
| Returns true if this tag set contains any tag set in the given other tag set. | |
| xiiUInt32 | GetNumTagsSet () const |
| Returns how many tags are in this set. | |
| bool | IsEmpty () const |
| True if the tag set never contained any tag or was cleared. | |
| void | Clear () |
| Removes all tags from the set. | |
| void | SetByName (xiiStringView sTag) |
| Adds the tag with the given name. If the tag does not exist, it will be registered. | |
| void | RemoveByName (xiiStringView sTag) |
| Removes the given tag. If it doesn't exist, nothing happens. | |
| bool | IsSetByName (xiiStringView sTag) const |
| Checks whether the named tag is part of this set. Returns false if the tag does not exist. | |
| bool | IsSetByName (const xiiTempHashedString &sTag) const |
| Checks whether the named tag is part of this set. Returns false if the tag does not exist. | |
| Iterator | GetIterator () const |
| Returns an iterator to list all tags in this set. | |
| void | Save (xiiStreamWriter &ref_stream) const |
| Writes the tag set state to a stream. Tags itself are serialized as strings. | |
| void | Load (xiiStreamReader &ref_stream, xiiTagRegistry &ref_registry) |
| Reads the tag set state from a stream and registers the tags with the given registry. | |

| class | Iterator |
A dynamic collection of tags featuring fast lookups.
This class can be used to store a (dynamic) collection of tags. Tags are registered within the global tag registry and allocated a bit index. The tag set allows comparatively fast lookups to check if a given tag is in the set or not. Adding a tag may have some overhead depending whether the block storage for the tag bit indices needs to be expanded or not (if the storage needs to be expanded the hybrid array will be resized). Typical storage requirements for a given tag set instance should be small since the block storage is a sliding window. The standard class which can be used is xiiTagSet, usage of xiiTagSetTemplate is only necessary if the allocator needs to be overridden.
