Detailed Description

The interface to the world data for elements.

Author:

Raphael Langerhorst

To allow maximum flexibility in agent design, agents can access data of other elements(!) through this interface. The implementation must be provided externally (through the GWE normally).

Note:

In case you hold sensitive data in one or another element and don't want all other elements to be able to access it, YOU need to provide security mechanisms. Potentially an agent can traverse through the whole element hierarchy and perform data mining. Be careful in untrusted environments were you are not in control of injected agents.

Todo:

write an algorithm to find a position transformation path between arbitrary elements

Member Function Documentation

virtual QList<GCS::GElementID> GCS::GWorldData::getChildren

(

const GCS::GElementID &

parent

)

const [pure virtual]

Returns:

the IDs of the children of given element.

Implemented in GWE::GXmlDataController.

virtual const GElement* GCS::GWorldData::read

(

const GElementID &

id

)

const [pure virtual]

The implementation is provided by the GWE, it allows read access to any element in the world. Normally an element more closely watches the element it is connected to. The GWorldData provides the possibility to read data from it, regardless how the remote element is accessed, which is accomplished by the GWE.

Implemented in GWE::GXmlDataController.
