public interface CompositeData
| Modifier and Type | Method and Description | 
|---|---|
| boolean | containsKey(String key)Returns true if and only if this CompositeData instance contains
 an item whose name is key. | 
| boolean | containsValue(Object value)Returns true if and only if this CompositeData instance contains an item
 whose value is value. | 
| boolean | equals(Object obj)Compares the specified obj parameter with this
  CompositeDatainstance for equality. | 
| Object | get(String key)Returns the value of the item whose name is key. | 
| Object[] | getAll(String[] keys)Returns an array of the values of the items whose names are specified by keys, in the same order as keys. | 
| CompositeType | getCompositeType()Returns the composite type  of this composite data instance. | 
| int | hashCode()Returns the hash code value for this  CompositeDatainstance. | 
| String | toString()Returns a string representation of this  CompositeDatainstance. | 
| Collection<?> | values()Returns an unmodifiable Collection view of the item values contained in this CompositeData instance. | 
CompositeType getCompositeType()
Object get(String key)
key - the name of the item.IllegalArgumentException - if key is a null or empty String.InvalidKeyException - if key is not an existing item name for this CompositeData instance.Object[] getAll(String[] keys)
keys - the names of the items.IllegalArgumentException - if an element in keys is a null or empty String.InvalidKeyException - if an element in keys is not an existing item name for this CompositeData instance.boolean containsKey(String key)
key - the key to be tested.boolean containsValue(Object value)
value - the value to be tested.Collection<?> values()
boolean equals(Object obj)
CompositeData instance for equality.
 Returns true if and only if all of the following statements are true:
CompositeData interface,deepEquals method
 for arrays of object reference types or the appropriate overloading of
 Arrays.equals(e1,e2) for arrays of primitive types
 This ensures that this equals method works properly for
 obj parameters which are different implementations of the
 CompositeData interface, with the restrictions mentioned in the
 equals
 method of the java.util.Collection interface.
equals in class Objectobj - the object to be compared for equality with this
 CompositeData instance.true if the specified object is equal to this
 CompositeData instance.Object.hashCode(), 
HashMapint hashCode()
CompositeData instance.
 
 The hash code of a CompositeData instance is the sum of the hash codes
 of all elements of information used in equals comparisons
 (ie: its composite type and all the item values).
 
 This ensures that  t1.equals(t2)  implies that  t1.hashCode()==t2.hashCode() 
 for any two CompositeData instances t1 and t2,
 as required by the general contract of the method
 Object.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
 deepHashCode method
 for arrays of object reference types or the appropriate overloading
 of Arrays.hashCode(e) for arrays of primitive types.
hashCode in class ObjectCompositeData instanceObject.equals(java.lang.Object), 
System.identityHashCode(java.lang.Object)String toString()
CompositeData instance.
 The string representation consists of the name of the implementing class, the string representation of the composite type of this instance, and the string representation of the contents (ie list the itemName=itemValue mappings).
