 javax.management.openmbean.OpenMBeanOperationInfoSupport
| Method Summary | |
| public boolean | equals(Object obj)
Compares the specified obj parameter with this OpenMBeanOperationInfoSupport instance for equality. | | public OpenType | getReturnOpenType()
Returns the open type of the values returned by the operation described by this OpenMBeanOperationInfo instance. | | public int | hashCode()
Returns the hash code value for this OpenMBeanOperationInfoSupport instance. | | public String | toString()
Returns a string representation of this OpenMBeanOperationInfoSupport instance. |
| OpenMBeanOperationInfoSupport | | public OpenMBeanOperationInfoSupport(String name, String description, OpenMBeanParameterInfo[] signature, OpenType returnOpenType, int impact)(Code) | | Constructs an OpenMBeanOperationInfoSupport instance, which describes the operation
of a class of open MBeans, with the specified
name, description, signature, returnOpenType and impact.
The signature array parameter is internally copied, so that subsequent changes
to the array referenced by signature have no effect on this instance.
Parameters:
name - cannot be a null or empty string.
Parameters:
description - cannot be a null or empty string.
Parameters:
signature - can be null or empty if there are no parameters to describe.
Parameters:
returnOpenType - cannot be null: use SimpleType.VOID for operations that return nothing.
Parameters:
impact - can be only one of ACTION, ACTION_INFO or INFO.
throws:
IllegalArgumentException - if name or description are null or empty string,or returnOpenType is null,or impact is not one of ACTION, ACTION_INFO or INFO.
throws:
ArrayStoreException - If signature is not an array of instances of a subclass of MBeanParameterInfo. |
| equals | | public boolean equals(Object obj)(Code) | | Compares the specified obj parameter with this OpenMBeanOperationInfoSupport instance for equality.
Returns true if and only if all of the following statements are true:
- obj is non null,
- obj also implements the
OpenMBeanOperationInfo interface,
- their names are equal
- their signatures are equal
- their return open types are equal
- their impacts are equal
This ensures that this equals method works properly for obj parameters which are
different implementations of the OpenMBeanOperationInfo interface.
Parameters:
obj - the object to be compared for equality with this OpenMBeanOperationInfoSupport instance; true if the specified object is equal to this OpenMBeanOperationInfoSupport instance. |
| getReturnOpenType | | public OpenType getReturnOpenType()(Code) | | Returns the open type of the values returned by the operation described by this OpenMBeanOperationInfo instance.
|
| hashCode | | public int hashCode()(Code) | | Returns the hash code value for this OpenMBeanOperationInfoSupport instance.
The hash code of an OpenMBeanOperationInfoSupport instance is the sum of the hash codes
of all elements of information used in equals comparisons
(ie: its name, return open type, impact and signature, where the signature hashCode is calculated by a call to
java.util.Arrays.asList(this.getSignature).hashCode()).
This ensures that t1.equals(t2) implies that t1.hashCode()==t2.hashCode()
for any two OpenMBeanOperationInfoSupport 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 OpenMBeanOperationInfo interface
may be equal to this OpenMBeanOperationInfoSupport instance as defined by
OpenMBeanOperationInfoSupport.equals(java.lang.Object) ,
but may have a different hash code if it is calculated differently.
As OpenMBeanOperationInfoSupport 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.

| toString | | public String toString()(Code) | | Returns a string representation of this OpenMBeanOperationInfoSupport instance.
The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanOperationInfoSupport),
and the name, signature, return open type and impact of the described operation.
As OpenMBeanOperationInfoSupport 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.
