Detailed Description

A service class querying and caching types.

Definition at line 23 of file TypeService.h.

Member Function Documentation

TypeInfo * Eris::TypeService::findTypeByName

(

const std::string &

tynm

)

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

Definition at line 51 of file TypeService.cpp.

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

TypeInfo * 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

Definition at line 61 of file TypeService.cpp.

TypeInfo * Eris::TypeService::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

Definition at line 77 of file TypeService.cpp.

References getTypeByName(), and sendRequest().

Referenced by Eris::View::taskRateChanged().

void Eris::TypeService::sendRequest

(

const std::string &

id

)

request the information about a type from the server.

Parameters

id	The ID of the type to lookup

Definition at line 155 of file TypeService.cpp.

Referenced by getTypeByName(), getTypeForAtlas(), and Eris::TypeInfo::refresh().

void Eris::TypeService::setTypeProviderId

(

std::string

id

)

Set another provider of type data than the connection.

This should be set to the external mind once an entity has been possessed, since the external mind has access to more type data (for example the type of the entity itself).

Parameters

id

Member Data Documentation

sigc::signal<void, TypeInfo*> Eris::TypeService::BadType

emitted when a type is confirmed as being undefined

Definition at line 47 of file TypeService.h.

Referenced by sendRequest().

sigc::signal<void, TypeInfo*> Eris::TypeService::BoundType

emitted when a new type is available and bound to it's parents

Definition at line 44 of file TypeService.h.

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

std::string Eris::TypeService::m_type_provider_id

protected

An optional type provider, to which requests for types are sent.

Definition at line 85 of file TypeService.h.

Referenced by sendRequest(), and setTypeProviderId().

std::unordered_map<std::string, std::unique_ptr<TypeInfo> > 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 efficiency considerations indicate it would be worthwhile
