javax.management.openmbean
Class OpenType<T>

java.lang.Object
  extended by javax.management.openmbean.OpenType<T>
Type Parameters:
T - the Java type that instances described by this type must have. For example, SimpleType.INTEGER is a SimpleType<Integer> which is a subclass of OpenType<Integer>, meaning that an attribute, parameter, or return value that is described as a SimpleType.INTEGER must have Java type Integer.
All Implemented Interfaces:
Serializable
Direct Known Subclasses:
ArrayType, CompositeType, SimpleType, TabularType

public abstract class OpenType<T>
extends Object
implements Serializable

The OpenType class is the parent abstract class of all classes which describe the actual open type of open data values.

An open type is defined by:

ALLOWED_CLASSNAMES_LIST

public static final List<String> ALLOWED_CLASSNAMES_LIST
List of the fully qualified names of the Java classes allowed for open data values. A multidimensional array of any one of these classes or their corresponding primitive types is also an allowed class for open data values.
ALLOWED_CLASSNAMES_LIST = {
        "java.lang.Void",
        "java.lang.Boolean",
        "java.lang.Character",
        "java.lang.Byte",

Constructor Detail

OpenType

protected OpenType(String className,
                   String typeName,
                   String description)
            throws OpenDataException
Constructs an OpenType instance (actually a subclass instance as OpenType is abstract), checking for the validity of the given parameters. The validity constraints are described below for each parameter.
 

Parameters:
className - The fully qualified Java class name of the open data values this open type describes. The valid Java class names allowed 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).
 
typeName - The name given to the open type this instance represents; cannot be a null or empty string.
 
description - The human readable description of the open type this instance represents; cannot be a null or empty string.
 
Throws:
IllegalArgumentException - if className, typeName or description is a null or empty string
 
OpenDataException - if className is not one of the allowed Java class names for open data
Method Detail

getClassName

public String getClassName()
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.

getTypeName

public String getTypeName()
Returns the name of this OpenType instance.

Returns:
the type name.

getDescription

public String getDescription()
Returns the text description of this OpenType instance.

Returns:
the description.

isArray

public boolean isArray()
Returns true if the open data values this open type describes are arrays, false otherwise.

Returns:
true if this is an array type.

isValue

public abstract boolean isValue(Object obj)
Tests whether obj is a value for this open type.

Parameters:
obj - the object to be tested for validity.
Returns:
true if obj is a value for this open type, false otherwise.

equals

public abstract boolean equals(Object obj)
Compares the specified obj parameter with this open type instance for equality.

Overrides:
equals in class Object
Parameters:
obj - the object to compare to.
Returns:
true if this object and obj are equal.
See Also:
Object.hashCode(), Hashtable

hashCode

public abstract int hashCode()
Description copied from class: Object
Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

The general contract of hashCode is:

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

Overrides:
hashCode in class Object
Returns:
a hash code value for this object.
See Also:
Object.equals(java.lang.Object), Hashtable

toString

public abstract String toString()
Returns a string representation of this open type instance.

Overrides:
toString in class Object
Returns:
the string representation.
