SimpleType (GNU libgcj 4.8.0 Documentation)

java.lang.Object
- javax.management.openmbean.OpenType<T>
- - javax.management.openmbean.SimpleType<T>

All Implemented Interfaces:

Serializable
```
public final class SimpleType<T>
extends OpenType<T>
```
The open type descriptor for data values that are members of one of the simple types (such as an integer or a string). The other open types (ArrayType, CompositeType, TabularType) are constructed from one or more of these types. The simple types are formed from a small subset of basic Java types. As a result, the valid instances of this class are predefined, and no constructor is given for creating new instances.

- Method Detail
  - equals
```
public boolean equals(Object obj)
```
    Compares this simple data type with another object for equality. The objects are judged to be equal if:
    - obj is not null.
    - obj is an instance of SimpleType.
    - The class names are equal.
    Specified by:
    
    equals in class OpenType<T>
    
    Parameters:
    obj - the object to compare with.
    
    Returns:
    true if the conditions above hold.
    See Also:
    Object.hashCode()
  - hashCode
```
public int hashCode()
```
    Returns the hash code of the simple data type. This is simply the hash code of the class name, which is the same element of the type compared as part of the equals(java.lang.Object) method, thus ensuring that the hashcode is compatible with the equality test.
    
    As instances of this class are immutable, the hash code is computed just once for each instance and reused throughout its life.
    
    Specified by:
    
    hashCode in class OpenType<T>
    
    Returns:
    the hash code of this instance.
    See Also:
    Object.equals(Object), System.identityHashCode(Object)
  - isValue
```
public boolean isValue(Object obj)
```
    Returns true if the specified object is a member of this simple type. The object is judged to be so if it is non-null and its class name is the same as that returned by OpenType.getClassName().
    
    Specified by:
    
    isValue in class OpenType<T>
    
    Parameters:
    obj - the object to test for membership.
    
    Returns:
    true if the object is a member of this type.
  - readResolve
```
public Object readResolve()
                   throws ObjectStreamException
```
    Replaces instances of this class read from an ObjectInputStream with one of the predefined values. This ensures that each existing instance of this class is one of these unique instances.
    
    Returns:
    the replacement object.
    
    Throws:
    
    ObjectStreamException - if the object can not be resolved.
  - toString
```
public String toString()
```
    Returns a textual representation of this instance. This is constructed using the class name (javax.management.openmbean.SimpleType) and the name of the class the type represents.
    
    As instances of this class are immutable, the return value is computed just once for each instance and reused throughout its life.
    
    Specified by:
    
    toString in class OpenType<T>
    
    Returns:
    a @link{java.lang.String} instance representing the instance in textual form.
