| equals | | public boolean equals(Object obj)(Code) | | Compares the specified obj parameter with this OpenMBeanAttributeInfoSupport 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.
Parameters:
obj - the object to be compared for equality with this OpenMBeanAttributeInfoSupport instance; true if the specified object is equal to this OpenMBeanAttributeInfoSupport instance. |
| getDefaultValue | | public Object getDefaultValue()(Code) | | Returns the default value for the attribute described by this OpenMBeanAttributeInfoSupport instance,
if specified, or null otherwise.
|
| getLegalValues | | public Set getLegalValues()(Code) | | Returns an unmodifiable Set of legal values for the attribute described by this OpenMBeanAttributeInfoSupport instance,
if specified, or null otherwise.
|
| getMaxValue | | public Comparable getMaxValue()(Code) | | Returns the maximal value for the attribute described by this OpenMBeanAttributeInfoSupport instance,
if specified, or null otherwise.
|
| getMinValue | | public Comparable getMinValue()(Code) | | Returns the minimal value for the attribute described by this OpenMBeanAttributeInfoSupport instance,
if specified, or null otherwise.
|
| getOpenType | | public OpenType getOpenType()(Code) | | Returns the open type for the values of the attribute described by this OpenMBeanAttributeInfoSupport instance.
|
| hasDefaultValue | | public boolean hasDefaultValue()(Code) | | Returns true if this OpenMBeanAttributeInfoSupport instance specifies a non-null default value
for the described attribute, false otherwise.
|
| hasLegalValues | | public boolean hasLegalValues()(Code) | | Returns true if this OpenMBeanAttributeInfoSupport instance specifies a non-null set of legal values
for the described attribute, false otherwise.
|
| hasMaxValue | | public boolean hasMaxValue()(Code) | | Returns true if this OpenMBeanAttributeInfoSupport instance specifies a non-null maximal value
for the described attribute, false otherwise.
|
| hasMinValue | | public boolean hasMinValue()(Code) | | Returns true if this OpenMBeanAttributeInfoSupport instance specifies a non-null minimal value
for the described attribute, false otherwise.
|
| hashCode | | public int hashCode()(Code) | | Returns the hash code value for this OpenMBeanAttributeInfoSupport instance.
The hash code of an OpenMBeanAttributeInfoSupport 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 OpenMBeanAttributeInfoSupport instances t1 and t2,
as required by the general contract of the method
Object.hashCode .
However, note that another instance of a class implementing the OpenMBeanAttributeInfo interface
may be equal to this OpenMBeanAttributeInfoSupport instance as defined by
OpenMBeanAttributeInfoSupport.equals(java.lang.Object) ,
but may have a different hash code if it is calculated differently.
As OpenMBeanAttributeInfoSupport 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.

| isValue | | public boolean isValue(Object obj)(Code) | | Tests whether obj is a valid value for the attribute
described by this OpenMBeanAttributeInfoSupport
instance.
Parameters:
obj - the object to be tested. true if obj is a valid value for for the parameter described bythis OpenMBeanAttributeInfoSupport instance, false otherwise. |
| toString | | public String toString()(Code) | | Returns a string representation of this OpenMBeanAttributeInfoSupport instance.
The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanAttributeInfoSupport),
the string representation of the name and open type of the described parameter,
and the string representation of its default, min, max and legal values.
As OpenMBeanAttributeInfoSupport 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.
