CompositeType JDK 1.6)

Constructors

public CompositeType (String typeName, String description, String itemNames, String itemDescriptions, OpenType<Object> itemTypes) throws OpenDataException

Constructs a CompositeType instance, checking for the validity of the given parameters.

Constructs a CompositeType instance, checking for the validity of the given parameters. The validity constraints are described below for each parameter.

Note that the contents of the three array parameters itemNames, itemDescriptions and itemTypes are internally copied so that any subsequent modification of these arrays by the caller of this constructor has no impact on the constructed CompositeType instance.

The Java class name of composite data values this composite type represents (ie the class name returned by the getClassName method) is set to the string value returned by CompositeData.class.getName().

Parameters:
- typeName - The name given to the composite type this instance represents; cannot be a null or empty string.

- description - The human readable description of the composite type this instance represents; cannot be a null or empty string.

- itemNames - The names of the items contained in the composite data values described by this CompositeType instance; cannot be null and should contain at least one element; no element can be a null or empty string. Note that the order in which the item names are given is not important to differentiate a CompositeType instance from another; the item names are internally stored sorted in ascending alphanumeric order.

- itemDescriptions - The descriptions, in the same order as itemNames, of the items contained in the composite data values described by this CompositeType instance; should be of the same size as itemNames; no element can be a null or empty string.

- itemTypes - The open type instances, in the same order as itemNames, describing the items contained in the composite data values described by this CompositeType instance; should be of the same size as itemNames; no element can be null.

Throws:
- IllegalArgumentException - If typeName or description is a null or empty string, or itemNames or itemDescriptions or itemTypes is null, or any element of itemNames or itemDescriptions is a null or empty string, or any element of itemTypes is null, or itemNames or itemDescriptions or itemTypes are not of the same size.

- OpenDataException - If itemNames contains duplicate item names (case sensitive, but leading and trailing whitespaces removed).

Methods

Hide/Show inherited methods

public boolean containsKey (String itemName)

Returns true if this CompositeType instance defines an item whose name is itemName.

Returns true if this CompositeType instance defines an item
whose name is itemName.
Returns: true if an item of this name is present.
Parameters:
- itemName - the name of the item.

public boolean equals (Object obj) [Specified in OpenType]

Compares the specified obj parameter with this CompositeType instance for equality.

Two CompositeType instances are equal if and only if all of the following statements are true:

their type names are equal
their items' names and types are equal

Returns: true if the specified object is equal to this CompositeType instance.
Parameters:
- obj - the object to be compared for equality with this CompositeType instance; if obj is null, equals returns false.

public String getClassName () [Inherited From OpenType]

Returns the fully qualified Java class name of the open data values this open type describes.

Returns the fully qualified Java class name of the open data values
this open type describes.
The only possible Java class names for open data values are listed in
ALLOWED_CLASSNAMES_LIST.
A multidimensional array of any one of these classes or their
corresponding primitive types is also an allowed class,
in which case the class name follows the rules defined by the method
getName() of java.lang.Class.
For example, a 3-dimensional array of Strings has for class name
"[[[Ljava.lang.String;" (without the quotes),
a 3-dimensional array of Integers has for class name
"[[[Ljava.lang.Integer;" (without the quotes),
and a 3-dimensional array of int has for class name
"[[[I" (without the quotes)
Returns: the class name.

public String getDescription () [Inherited From OpenType]

Returns the text description of this OpenType instance.

Returns the text description of this OpenType instance.
Returns: the description.

public String getDescription (String itemName)

Returns the description of the item whose name is itemName, or null if this CompositeType instance does not define any item whose name is itemName.

Returns the description of the item whose name is itemName,
or null if this CompositeType instance does not define any item
whose name is itemName.
Returns: the description.
Parameters:
- itemName - the name of the item.

pack-privatesynchronized Descriptor getDescriptor () [Inherited From OpenType]

public OpenType<Object> getType (String itemName)

Returns the open type of the item whose name is itemName, or null if this CompositeType instance does not define any item whose name is itemName.

Returns the open type of the item whose name is itemName,
or null if this CompositeType instance does not define any item
whose name is itemName.
Returns: the type.
Parameters:
- itemName - the name of the time.

public String getTypeName () [Inherited From OpenType]

Returns the name of this OpenType instance.

Returns the name of this OpenType instance.
Returns: the type name.

public int hashCode () [Specified in OpenType]

Returns the hash code value for this CompositeType instance.

The hash code of a CompositeType instance is the sum of the hash codes of all elements of information used in equals comparisons (ie: name, items names, items types). This ensures that t1.equals(t2) implies that t1.hashCode()==t2.hashCode() for any two CompositeType instances t1 and t2, as required by the general contract of the method Object.hashCode().

As CompositeType instances are immutable, the hash code for this instance is calculated once, on the first call to hashCode, and then the same value is returned for subsequent calls.
Returns: the hash code value for this CompositeType instance

public boolean isArray () [Inherited From OpenType]

Returns true if the open data values this open type describes are arrays, false otherwise.

Returns true if the open data values this open
type describes are arrays, false otherwise.
Returns: true if this is an array type.

@Override

pack-private boolean isAssignableFrom (OpenType ot)

Tests whether values of the given type can be assigned to this open type.

pack-private boolean isAssignableFrom (OpenType<Object> ot) [Inherited From OpenType]

Tests whether values of the given type can be assigned to this open type.

public boolean isValue (Object obj) [Specified in OpenType]

Tests whether obj is a value which could be described by this CompositeType instance.

If obj is null or is not an instance of javax.management.openmbean.CompositeData, isValue returns false.

If obj is an instance of javax.management.openmbean.CompositeData, then let ct be its CompositeType as returned by CompositeData.getCompositeType(). The result is true if this is assignable from ct. This means that:

this.getTypeName() equals ct.getTypeName(), and
there are no item names present in this that are not also present in ct, and
for every item in this, its type is assignable from the type of the corresponding item in ct.

A TabularType is assignable from another TabularType if they have the same typeName and index name list, and the row type of the first is assignable from the row type of the second.

An ArrayType is assignable from another ArrayType if they have the same dimension; and both are primitive arrays or neither is; and the element type of the first is assignable from the element type of the second.

In every other case, an OpenType is assignable from another OpenType only if they are equal.

These rules mean that extra items can be added to a CompositeData without making it invalid for a CompositeType that does not have those items.

Returns: true if obj is a value for this composite type, false otherwise.
Parameters:
- obj - the value whose open type is to be tested for compatibility with this CompositeType instance.

public Set<String> keySet ()

Returns an unmodifiable Set view of all the item names defined by this CompositeType instance.

Returns an unmodifiable Set view of all the item names defined by this CompositeType instance.
The set's iterator will return the item names in ascending order.
Returns: a {@link Set} of {@link String}.

public String toString () [Specified in OpenType]

Returns a string representation of this CompositeType instance.

The string representation consists of the name of this class (ie javax.management.openmbean.CompositeType), the type name for this instance, and the list of the items names and types string representation of this instance.

As CompositeType instances are immutable, the string representation for this instance is calculated once, on the first call to toString, and then the same value is returned for subsequent calls.
Returns: a string representation of this CompositeType instance
