                     throws OpenDataException

Construct Composite Data

Parameters:

compositeType - the composite type of the data

itemNames - the names of the values

itemValues - the values

Throws:

IllegalArgumentException - for a null or empty argument

OpenDataException - when the items do not match the CompositeType

CompositeDataSupport

public CompositeDataSupport(CompositeType compositeType,
                            Map items)
                     throws OpenDataException

Construct Composite Data

Parameters:

compositeType - the composite type of the data

items - map of strings to values

Throws:

IllegalArgumentException - for a null or empty argument

OpenDataException - when the items do not match the CompositeType

ArrayStoreException - when a key to the map is not a String
