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.

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.
equals in class OpenType<T>obj - the object to be compared for equality with this SimpleType instance;
if obj is null or is not an instance of the class SimpleType,
equals returns false.true if the specified object is equal to this SimpleType instance.Object.hashCode(),
HashMappublic int hashCode()
SimpleType instance.
The hash code of a SimpleType instance is the 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.
hashCode in class OpenType<T>SimpleType instanceObject.equals(java.lang.Object),
System.identityHashCode(java.lang.Object)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. Submit a bug or feature
