OpenJDK 1.23 · javax.management.openmbean.SimpleType

The 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 Detail

equals back to summary

equals	back to summary
public boolean equals(Object obj) Implements abstract javax.management.openmbean.OpenType.equals. Compares the specified `obj` parameter with this `SimpleType` instance for equality. Two `SimpleType` instances are equal if and only if their `getClassName` methods return the same value. Parameters obj:Object 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`. Returns:boolean `true` if the specified object is equal to this `SimpleType` instance.

public boolean equals(Object obj)

Implements abstract javax.management.openmbean.OpenType.equals.

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

Two SimpleType instances are equal if and only if their getClassName methods return the same value.

Parameters

obj:Object: 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.

Returns:boolean

true if the specified object is equal to this SimpleType instance.

hashCode back to summary

hashCode	back to summary
public int hashCode() Implements abstract javax.management.openmbean.OpenType.hashCode. Returns the hash code value for this `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. Returns:int the hash code value for this `SimpleType` instance

public int hashCode()

Implements abstract javax.management.openmbean.OpenType.hashCode.

Returns the hash code value for this 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.

Returns:int: the hash code value for this SimpleType instance

isValue back to summary

isValue	back to summary
public boolean isValue(Object obj) Implements abstract javax.management.openmbean.OpenType.isValue. Tests whether `obj` is a value for this `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). Parameters obj:Object the object to be tested. Returns:boolean `true` if `obj` is a value for this `SimpleType` instance.

public boolean isValue(Object obj)

Implements abstract javax.management.openmbean.OpenType.isValue.

Tests whether obj is a value for this 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).

Parameters

obj:Object: the object to be tested.

Returns:boolean

true if obj is a value for this SimpleType instance.

readResolve back to summary

readResolve	back to summary
public Object readResolve() throws ObjectStreamException Replace an object read from an `java.io.ObjectInputStream` with the unique instance for that value. Returns:Object the replacement object. Exceptions ObjectStreamException: if the read object cannot be resolved.

public Object readResolve() throws ObjectStreamException

Returns:Object

the replacement object.

Exceptions

ObjectStreamException:: if the read object cannot be resolved.

toString back to summary

toString	back to summary
public String toString() Implements abstract javax.management.openmbean.OpenType.toString. Returns a string representation of this `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. Returns:String a string representation of this `SimpleType` instance

public String toString()

Implements abstract javax.management.openmbean.OpenType.toString.

Returns a string representation of this 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.

Returns:String: a string representation of this SimpleType instance
