= Looking up Model information (meta-data) at run-time =

!InfoGrid makes all [wiki:Model] information (i.e. all meta-data) available at run-time for [wiki:MeshObject MeshObjects].

== Related to !EntityType ==

Given a MeshObject:
{{{
MeshObject obj = ...;
}}}

To determine the [wiki:EntityType EntityTypes] with which it is blessed:
{{{
EntityType [] types = obj.getTypes();
}}}

To determine whether the MeshObject is blessed with a particular EntityType:
{{{
EntityType toCheck = ...;
if( obj.isBlessedBy( toCheck )) {
    ...
}
}}}

== Related to !PropertyType ==

To determine all [wiki:PropertyType PropertyTypes] currently available:
{{{
PropertyType [] propertyTypes = obj.getAllPropertyTypes();
}}}

To determine the values of all [wiki:Property Properties]:
{{{
PropertyType []  propertyTypes  = obj.getAllPropertyTypes();
PropertyValue [] propertyValues = obj.getPropertyValues( propertyTypes );
}}}
They [wiki:PropertyValue PropertyValues] will be returned in the same sequence as the [wiki:PropertyType PropertyTypes].

== Related to !RoleType ==

To determine the all [wiki:RoleType RoleTypes] that the MeshObject currently plays:
{{{
RoleType [] allRoleTypes = obj.getAllRoleTypes();
}}}

To also determine with which neighbor MeshObject the MeshObject currently plays which RoleType:
{{{
Role [] allRoles = obj.getRoles();
}}}
`Role` brings together both the RoleType and the neighbor MeshObject.

To determine the [wiki:RoleType RoleTypes] that the MeshObject currently plays with a given neighbor MeshObject:
{{{
MeshObject  neighbor     = ...;
RoleType [] withNeighbor = obj.getRoleTypes( neighbor );
}}}

== Traversing the Model further ==

The [wiki:MeshType MeshTypes] constituting the [wiki:Model] can be fully explored through methods exposed on the various [wiki:MeshType MeshTypes].

For example, given an EntityType, determine which [wiki:RelationshipType RelationshipTypes] require this EntityType as source or destination:
{{{
EntityType  type = ...;
RoleType [] playsRoleTypes = type.getAllRoleTypes();
}}}
