T
- the Java type that values described by this SimpleType must have.Serializable
public final class SimpleType<T> extends OpenType<T>
SimpleType
class is the open type class whose instances describe all open data values which are neither arrays, nor CompositeData
values, nor TabularData
values. It predefines all its possible instances as static fields, and has no public constructor. Given a SimpleType
instance describing values whose Java class name is className, the internal fields corresponding to the name and description of this SimpleType
instance are also set to className. In other words, its methods getClassName
, getTypeName
and getDescription
all return the same string value className.

.public static final SimpleType<ObjectName> OBJECTNAME
SimpleType
instance describing values whose Java class name is javax.management.ObjectName
.public boolean isValue(Object obj)
SimpleType
instance. This method returns true
if and only if obj is not null and obj's class name is the same as the className field defined for this SimpleType
instance (ie the class name returned by the getClassName
method).
public boolean equals(Object obj)
obj
parameter with this SimpleType
instance for equality. Two SimpleType
instances are equal if and only if their getClassName
methods return the same value.
public int hashCode()
SimpleType
instance. The hash code of a SimpleType
instance is the hash code of the string value returned by the getClassName
method. As SimpleType
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.
public String toString()
SimpleType
instance. The string representation consists of the name of this class (ie javax.management.openmbean.SimpleType
) and the type name for this instance (which is the java class name of the values this SimpleType
instance represents).
As SimpleType
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.
public Object readResolve() throws ObjectStreamException
ObjectInputStream
with the unique instance for that value.ObjectStreamException
- if the read object cannot be resolved.
