Constructor Detail- 
CompositeDataSupportpublic CompositeDataSupport(CompositeType compositeType, String[] itemNames, Object[] itemValues) throws OpenDataException Constructs a CompositeDataSupportinstance with the specifiedcompositeType, whose item values are specified byitemValues[], in the same order as initemNames[]. As aCompositeTypedoes not specify any order on its items, theitemNames[]parameter is used to specify the order in which the values are given initemValues[]. The items contained in thisCompositeDataSupportinstance are internally stored in aTreeMap, 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-- itemNamesmust 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- compositeTypefor the corresponding item; must be of the same size as- itemNames; must not be null or empty.
- Throws:
- IllegalArgumentException-- compositeTypeis 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.

CompositeDataSupportpublic CompositeDataSupport(CompositeType compositeType, Map<String,?> items) throws OpenDataException Constructs a CompositeDataSupportinstance with the specifiedcompositeType, whose item names and corresponding values are given by the mappings in the mapitems. This constructor converts the keys to a string array and the values to an object array and callsCompositeDataSupport(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;- itemsmust contain all the item names defined in- compositeType; must not be null or empty.
- Throws:
- IllegalArgumentException-- compositeTypeis null, or- itemsis null or empty, or one of the keys in- itemsis a null or empty string.
- OpenDataException-- items' size differs from the number of items defined in- compositeType, or one of the keys in- itemsdoes not exist as an item name defined in- compositeType, or one of the values in- itemsis not a valid value for the corresponding item as defined in- compositeType.
- ArrayStoreException- one or more keys in- itemsis not of the class- java.lang.String.

Method Detail- 
getCompositeTypepublic CompositeType getCompositeType() Returns the composite type of this composite data instance.- Specified by:
- getCompositeTypein interface- CompositeData
- Returns:
- the type of this CompositeData.
 
 - 
getpublic Object get(String key) Returns the value of the item whose name iskey.- Specified by:
- getin interface- CompositeData
- Parameters:
- key- the name of the item.
- Returns:
- the value associated with this key.
- Throws:
- IllegalArgumentException- if- keyis a null or empty String.
- InvalidKeyException- if- keyis not an existing item name for this- CompositeDatainstance.
 
 - 
getAllpublic Object[] getAll(String[] keys) Returns an array of the values of the items whose names are specified bykeys, in the same order askeys.- Specified by:
- getAllin interface- CompositeData
- Parameters:
- keys- the names of the items.
- Returns:
- the values corresponding to the keys.
- Throws:
- IllegalArgumentException- if an element in- keysis a null or empty String.
- InvalidKeyException- if an element in- keysis not an existing item name for this- CompositeDatainstance.
 
 - 
containsKeypublic boolean containsKey(String key) Returnstrueif and only if thisCompositeDatainstance contains an item whose name iskey. Ifkeyis a null or empty String, this method simply returns false.- Specified by:
- containsKeyin interface- CompositeData
- Parameters:
- key- the key to be tested.
- Returns:
- true if this CompositeDatacontains the key.
 
 - 
containsValuepublic boolean containsValue(Object value) Returnstrueif and only if thisCompositeDatainstance contains an item whose value isvalue.- Specified by:
- containsValuein interface- CompositeData
- Parameters:
- value- the value to be tested.
- Returns:
- true if this CompositeDatacontains the value.
 
 - 
valuespublic Collection<?> values() Returns an unmodifiable Collection view of the item values contained in thisCompositeDatainstance. The returned collection's iterator will return the values in the ascending lexicographic order of the corresponding item names.- Specified by:
- valuesin interface- CompositeData
- Returns:
- the values.
 
 - 
equalspublic boolean equals(Object obj) Compares the specified obj parameter with thisCompositeDataSupportinstance for equality.Returns trueif and only if all of the following statements are true:- obj is non null,
- obj also implements the CompositeDatainterface,
- their composite types are equal
- their contents, i.e. (name, value) pairs are equal. If a value contained in
 the content is an array, the value comparison is done as if by calling
 the deepEqualsmethod for arrays of object reference types or the appropriate overloading ofArrays.equals(e1,e2)for arrays of primitive types
 This ensures that this equalsmethod works properly for obj parameters which are different implementations of theCompositeDatainterface, with the restrictions mentioned in theequalsmethod of thejava.util.Collectioninterface.- Specified by:
- equalsin interface- CompositeData
- Overrides:
- equalsin class- Object
- Parameters:
- obj- the object to be compared for equality with this- CompositeDataSupportinstance.
- Returns:
- trueif the specified object is equal to this- CompositeDataSupportinstance.
- See Also:
- Object.hashCode(),- HashMap
 
 - 
hashCodepublic int hashCode() Returns the hash code value for thisCompositeDataSupportinstance.The hash code of a CompositeDataSupportinstance is the sum of the hash codes of all elements of information used inequalscomparisons (ie: its composite type and all the item values).This ensures that t1.equals(t2)implies thatt1.hashCode()==t2.hashCode()for any twoCompositeDataSupportinstancest1andt2, as required by the general contract of the methodObject.hashCode().Each item value's hash code is added to the returned hash code. If an item value is an array, its hash code is obtained as if by calling the deepHashCodemethod for arrays of object reference types or the appropriate overloading ofArrays.hashCode(e)for arrays of primitive types.- Specified by:
- hashCodein interface- CompositeData
- Overrides:
- hashCodein class- Object
- Returns:
- the hash code value for this CompositeDataSupportinstance
- See Also:
- Object.equals(java.lang.Object),- System.identityHashCode(java.lang.Object)
 
 - 
toStringpublic String toString() Returns a string representation of thisCompositeDataSupportinstance.The string representation consists of the name of this class (ie javax.management.openmbean.CompositeDataSupport), the string representation of the composite type of this instance, and the string representation of the contents (ie list the itemName=itemValue mappings).- Specified by:
- toStringin interface- CompositeData
- Overrides:
- toStringin class- Object
- Returns:
- a string representation of this CompositeDataSupportinstance
