CompositeData

Fields Summary

Constructors Summary

Methods Summary
public boolean	containsKey(java.lang.String key) Returns true if and only if this CompositeData instance contains an item whose name is key. If key is a null or empty String, this method simply returns false. param key the key to be tested. return true if this CompositeData contains the key.
public boolean	containsValue(java.lang.Object value) Returns true if and only if this CompositeData instance contains an item whose value is value. param value the value to be tested. return true if this CompositeData contains the value.
public boolean	equals(java.lang.Object obj) Compares the specified obj parameter with this CompositeData instance for equality. Returns true if and only if all of the following statements are true: obj is non null, obj also implements the CompositeData interface, 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 {@link java.util.Arrays#deepEquals(Object[], Object[]) deepEquals} method for arrays of object reference types or the appropriate overloading of {@code 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 {@link java.util.Collection#equals(Object) equals} method of the java.util.Collection interface. param obj the object to be compared for equality with this CompositeData instance. return true if the specified object is equal to this CompositeData instance.
public java.lang.Object	get(java.lang.String key) Returns the value of the item whose name is key. param key the name of the item. return the value associated with this key. throws IllegalArgumentException if key is a null or empty String. throws InvalidKeyException if key is not an existing item name for this CompositeData instance.
public java.lang.Object[]	getAll(java.lang.String[] keys) Returns an array of the values of the items whose names are specified by keys, in the same order as keys. param keys the names of the items. return the values corresponding to the keys. throws IllegalArgumentException if an element in keys is a null or empty String. throws InvalidKeyException if an element in keys is not an existing item name for this CompositeData instance.
public javax.management.openmbean.CompositeType	getCompositeType() Returns the composite type of this composite data instance. return the type of this CompositeData.
public int	hashCode() Returns the hash code value for this 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 {@link Object#hashCode() 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 {@link java.util.Arrays#deepHashCode(Object[]) deepHashCode} method for arrays of object reference types or the appropriate overloading of {@code Arrays.hashCode(e)} for arrays of primitive types. return the hash code value for this CompositeData instance
public java.lang.String	toString() Returns a string representation of this 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). return a string representation of this CompositeData instance
public java.util.Collection	values() Returns an unmodifiable Collection view of the item values contained in this CompositeData instance. The returned collection's iterator will return the values in the ascending lexicographic order of the corresponding item names. return the values.
