Constructor Details

CompositeDataSupport

public CompositeDataSupport(CompositeType compositeType,
 String[] itemNames,
 Object[] itemValues)
                     throws OpenDataException

Constructs a CompositeDataSupport instance with the specified compositeType, whose item values are specified by itemValues[], in the same order as in itemNames[]. As a CompositeType does not specify any order on its items, the itemNames[] parameter is used to specify the order in which the values are given in itemValues[]. The items contained in this CompositeDataSupport instance are internally stored in a TreeMap, thus sorted in ascending lexicographic order of their names, for faster retrieval of individual item values.

The constructor checks that all the constraints listed below for each parameter are satisfied, and throws the appropriate exception if they are not.

Parameters:

compositeType - the composite type of this composite data instance; must not be null.

itemNames - itemNames must list, in any order, all the item names defined in compositeType; the order in which the names are listed, is used to match values in itemValues[]; must not be null or empty.

itemValues - the values of the items, listed in the same order as their respective names in itemNames; each item value can be null, but if it is non-null it must be a valid value for the open type defined in compositeType for the corresponding item; must be of the same size as itemNames; must not be null or empty.

Throws:

IllegalArgumentException - compositeType is null, or itemNames[] or itemValues[] is null or empty, or one of the elements in itemNames[] is a null or empty string, or itemNames[] and itemValues[] are not of the same size.

OpenDataException - itemNames[] or itemValues[]'s size differs from the number of items defined in compositeType, or one of the elements in itemNames[] does not exist as an item name defined in compositeType, or one of the elements in itemValues[] is not a valid value for the corresponding item as defined in compositeType.

CompositeDataSupport

public CompositeDataSupport(CompositeType compositeType,
 Map<String,?> items)
                     throws OpenDataException

Constructs a CompositeDataSupport instance with the specified compositeType, whose item names and corresponding values are given by the mappings in the map items. This constructor converts the keys to a string array and the values to an object array and calls CompositeDataSupport(javax.management.openmbean.CompositeType, java.lang.String[], java.lang.Object[]).

Parameters:

compositeType - the composite type of this composite data instance; must not be null.

items - the mappings of all the item names to their values; items must contain all the item names defined in compositeType; must not be null or empty.

Throws:

IllegalArgumentException - compositeType is null, or items is null or empty, or one of the keys in items is a null or empty string.

OpenDataException - items' size differs from the number of items defined in compositeType, or one of the keys in items does not exist as an item name defined in compositeType, or one of the values in items is not a valid value for the corresponding item as defined in compositeType.

ArrayStoreException - one or more keys in items is not of the class java.lang.String.
