OpenMBeanAttributeInfo

All Superinterfaces:

OpenMBeanParameterInfo

All Known Implementing Classes:

OpenMBeanAttributeInfoSupport
```
public interface OpenMBeanAttributeInfo
extends OpenMBeanParameterInfo
```
Describes an attribute of an open MBean.

This interface declares the same methods as the class MBeanAttributeInfo. A class implementing this interface (typically OpenMBeanAttributeInfoSupport) should extend MBeanAttributeInfo.

Since:

1.5

Instance Methods

Abstract Methods
Modifier and Type	Method and Description
`boolean`	`equals(Object obj)` Compares the specified obj parameter with this `OpenMBeanAttributeInfo` instance for equality.
`int`	`hashCode()` Returns the hash code value for this `OpenMBeanAttributeInfo` instance.
`boolean`	`isIs()` Returns `true` if the attribute described by this `OpenMBeanAttributeInfo` instance is accessed through a `isXXX` getter (applies only to `boolean` and `Boolean` values), `false` otherwise.
`boolean`	`isReadable()` Returns `true` if the attribute described by this `OpenMBeanAttributeInfo` instance is readable, `false` otherwise.
`boolean`	`isWritable()` Returns `true` if the attribute described by this `OpenMBeanAttributeInfo` instance is writable, `false` otherwise.
`String`	`toString()` Returns a string representation of this `OpenMBeanAttributeInfo` instance.

- Method Detail
  - isReadable
```
boolean isReadable()
```
    Returns true if the attribute described by this OpenMBeanAttributeInfo instance is readable, false otherwise.
    
    Returns:
    
    true if the attribute is readable.
  - isWritable
```
boolean isWritable()
```
    Returns true if the attribute described by this OpenMBeanAttributeInfo instance is writable, false otherwise.
    
    Returns:
    
    true if the attribute is writable.
  - isIs
```
boolean isIs()
```
    Returns true if the attribute described by this OpenMBeanAttributeInfo instance is accessed through a isXXX getter (applies only to boolean and Boolean values), false otherwise.
    
    Returns:
    
    true if the attribute is accessed through isXXX.
  - equals
```
boolean equals(Object obj)
```
    Compares the specified obj parameter with this OpenMBeanAttributeInfo instance for equality.
    Returns true if and only if all of the following statements are true:
    - obj is non null,
    - obj also implements the OpenMBeanAttributeInfo interface,
    - their names are equal
    - their open types are equal
    - their access properties (isReadable, isWritable and isIs) are equal
    - their default, min, max and legal values are equal.
    This ensures that this equals method works properly for obj parameters which are different implementations of the OpenMBeanAttributeInfo interface.
    Specified by:
    
    equals in interface OpenMBeanParameterInfo
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the object to be compared for equality with this OpenMBeanAttributeInfo instance;
    
    Returns:
    
    true if the specified object is equal to this OpenMBeanAttributeInfo instance.
    
    See Also:
    
    Object.hashCode(), HashMap
  - hashCode
```
int hashCode()
```
    Returns the hash code value for this OpenMBeanAttributeInfo instance.
    The hash code of an OpenMBeanAttributeInfo instance is the sum of the hash codes of all elements of information used in equals comparisons (ie: its name, its open type, and its default, min, max and legal values).
    
    This ensures that t1.equals(t2) implies that t1.hashCode()==t2.hashCode() for any two OpenMBeanAttributeInfo instances t1 and t2, as required by the general contract of the method Object.hashCode().
    
    Specified by:
    
    hashCode in interface OpenMBeanParameterInfo
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    the hash code value for this OpenMBeanAttributeInfo instance
    
    See Also:
    
    Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)
  - toString
```
String toString()
```
    Returns a string representation of this OpenMBeanAttributeInfo instance.
    The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanAttributeInfo), the string representation of the name and open type of the described attribute, and the string representation of its default, min, max and legal values.
    
    Specified by:
    
    toString in interface OpenMBeanParameterInfo
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a string representation of this OpenMBeanAttributeInfo instance
