IDataItem Properties

Properties

IndexList

For each element this can specify an index into another list where the data "belongs" to.

This can be null (if no reasonable correspondence exists or if the correspondence is trivial and therefor not needed ([0,1,2,3,...])).

For data on a reach, the element at index i in the IndexList having IndexList[i] = j is used to specify that the value belongs to GridPoint number j in a list of GridPoint's.

ItemId Id of item that this quantity belongs to. Null if not relevant.

Used e.g. to store the Id of the structure that the data belongs to.

ItemTypeGroup Describes what data group the data belongs to
NumberOfElements Number of elements.
NumberOfTimeSteps Number of time steps in data item.

Matches NumberOfTimeSteps, unless data for DataItem is not loaded, in which case it is zero

NumberWithinGroup Number within the group of ItemTypeGroup. Zero based.

If the number is -1, then the data belongs to all items within the ItemTypeGroup, i.e. if the ItemTypeGroup is NodeItem, then there is data for all nodes in the network.

Quantity Quantity description
TimeData List of time step data. Each list member contains data for one time step, The list has NumberOfTimeSteps elements.
VectorData Flag indicating if data item contains vector data or single value data
