OpenMBeanParameterInfo (Java Platform SE 8 )

All Known Subinterfaces:

OpenMBeanAttributeInfo

All Known Implementing Classes:

OpenMBeanAttributeInfoSupport, OpenMBeanParameterInfoSupport
```
public interface OpenMBeanParameterInfo
```
Describes a parameter used in one or more operations or constructors of an open MBean.

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

1.5

boolean hasDefaultValue()
```
    Returns true if this parameter has a specified default value, or false otherwise.
    
    Returns:
    
    true if there is a default value.
  - hasLegalValues
```
boolean hasLegalValues()
```
    Returns true if this parameter has a specified set of legal values, or false otherwise.
    
    Returns:
    
    true if there is a set of legal values.
  - hasMinValue
```
boolean hasMinValue()
```
    Returns true if this parameter has a specified minimal value, or false otherwise.
    
    Returns:
    
    true if there is a minimum value.
  - hasMaxValue
```
boolean hasMaxValue()
```
    Returns true if this parameter has a specified maximal value, or false otherwise.
    
    Returns:
    
    true if there is a maximum value.
  - isValue
```
boolean isValue(Object obj)
```
    Tests whether obj is a valid value for the parameter described by this OpenMBeanParameterInfo instance.
    
    Parameters:
    
    obj - the object to be tested.
    
    Returns:
    
    true if obj is a valid value for the parameter described by this OpenMBeanParameterInfo instance, false otherwise.
  - equals
```
boolean equals(Object obj)
```
    Compares the specified obj parameter with this OpenMBeanParameterInfo instance for equality.
    Returns true if and only if all of the following statements are true:
    - obj is non null,
    - obj also implements the OpenMBeanParameterInfo interface,
    - their names are equal
    - their open types 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 OpenMBeanParameterInfo interface.
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the object to be compared for equality with this OpenMBeanParameterInfo instance;
    
    Returns:
    
    true if the specified object is equal to this OpenMBeanParameterInfo instance.
    
    See Also:
    
    Object.hashCode(), HashMap
  - hashCode
```
int hashCode()
```
    Returns the hash code value for this OpenMBeanParameterInfo instance.
    The hash code of an OpenMBeanParameterInfo 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 OpenMBeanParameterInfo instances t1 and t2, as required by the general contract of the method Object.hashCode().
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    the hash code value for this OpenMBeanParameterInfo instance
    
    See Also:
    
    Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)
  - toString
```
String toString()
```
    Returns a string representation of this OpenMBeanParameterInfo instance.
    The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanParameterInfo), 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.
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a string representation of this OpenMBeanParameterInfo instance
