TypeInfoPtr	getTypeForAtlas (const Atlas::Objects::Root &obj)
	retrive the TypeInfo for an object; this should be faster (hopefully constant time) since it can take advantage of integer typeids

Detailed Description

A service class querying and caching types.

Member Function Documentation

TypeInfoPtr Eris::TypeService::findTypeByName

(

const std::string &

tynm

)

Lookup the requested type, by name, and return NULL if it's unknown.

References m_types.

Referenced by Eris::TypeInfo::processTypeData().

TypeInfoPtr Eris::TypeService::getTypeByName

(

const std::string &

tynm

)

find the TypeInfo for the named type; this may involve a search, or a map lookup.

The returned TypeInfo node may not be bound, and the caller should verify this before using the type.

Todo:

Verify the id is not in the authoritative invalid ID list

References m_types, and sendRequest().

Referenced by getTypeForAtlas(), Eris::Entity::getUseOperations(), Eris::TypeInfo::processTypeData(), and Eris::TypeInfo::resolveChildren().

void Eris::TypeService::sendRequest ( const std::string &  id )

protected

request the information about a type from the server.

Parameters

id	The ID of the type to lookup

References Eris::Connection::send().

Referenced by getTypeByName().

Member Data Documentation

TypeInfoMap Eris::TypeService::m_types

protected

The easy bit : a simple map from 'string-id' (e.g 'look' or 'farmer') to the corresponding TypeInfo instance.

This could be a hash_map in the future, if efficeny consdierations indicate it would be worthwhile

Referenced by findTypeByName(), and getTypeByName().
