Constructor Details

MetaDataType

public MetaDataType(String id)

Parameters:

id - String; id

Method Details

getId

public final String getId()

Specified by:

getId in interface Identifiable

Returns:

id.

getValue

public abstract T getValue(GtuDataInterface gtu)

Retrieves the value of the meta data of this type from a GTU.

Parameters:

gtu - GtuDataInterface; gtu to retrieve the value from

Returns:

value of the meta data of this type from a GTU, may be null if not applicable.

formatValue

public abstract String formatValue(String format, T value)

Formats the value into a string. If the value is numeric, the default implementation is:

 String.format(format, value.si);
 

Parameters:

format - String; format

value - T; value

Returns:

formatted value

accept

public void accept(TrajectoryAcceptList trajectoryAcceptList, Set<T> querySet)

Determines for a set of trajectory's from a single GTU, which may be accepted according to this meta data type. As a single GTU may have several trajectories for a single TrajectoryGroup object, the specified TrajectoryGroup's may have duplicates. As the trajectory's are from a single GTU, the meta data is equal for all. Implementations of this method may for instance:

1. Determine only from the first Trajectorys' meta data that all may be accepted.
2. Determine for the separate Trajectory's whether they are acceptable.
3. The same as 2, but refuse all if any is refused.
4. The same as 2, but accept all if any is accepted.
5. etc.

The default implementation is that of 1, checking that the meta data value is in the provided query set.

Parameters:

trajectoryAcceptList - TrajectoryAcceptList; containing Trajectory's and TrajectoryGroup's pertaining to a single GTU

querySet - Set<T>; set of values in the query for this metadata type

toString

public String toString()

Overrides:

toString in class Object
