Serializable
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.

Method Details
-
isValue
Tests whether obj is a value for thisSimpleTypeinstance.This method returns
trueif and only if obj is not null and obj's class name is the same as the className field defined for thisSimpleTypeinstance (ie the class name returned by thegetClassNamemethod). -
equals
Compares the specifiedobjparameter with thisSimpleTypeinstance for equality.Two
SimpleTypeinstances are equal if and only if theirgetClassNamemethods return the same value. -
hashCode
public int hashCode()Returns the hash code value for thisSimpleTypeinstance. The hash code of aSimpleTypeinstance is the hash code of the string value returned by thegetClassNamemethod.As
SimpleTypeinstances are immutable, the hash code for this instance is calculated once, on the first call tohashCode, and then the same value is returned for subsequent calls. -
toString
Returns a string representation of thisSimpleTypeinstance.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 thisSimpleTypeinstance represents).As
SimpleTypeinstances are immutable, the string representation for this instance is calculated once, on the first call totoString, and then the same value is returned for subsequent calls. -
readResolve
Replace an object read from anObjectInputStreamwith the unique instance for that value.- Returns:
- the replacement object.
- Throws:
ObjectStreamException- if the read object cannot be resolved.
