Retrieve a human readable description of the open MBean parameter the implementation of this interface describes.

Returns:

the description.

getName

String getName()

Retrieve the name of the parameter described.

Returns:

the name.

getOpenType

OpenType getOpenType()

Retrieve the open type for this parameter

Returns:

the open type.

getDefaultValue

Object getDefaultValue()

Retrieve the default value for this parameter or null if there is no default

Returns:

the default value

getLegalValues

Set getLegalValues()

Retrieve the legal values values for this parameter or null if this is not specified

Returns:

the legal value

getMinValue

Comparable getMinValue()

Retrieve the minimum values values for this parameter or null if this is not specified

Returns:

the minimum value

getMaxValue

Comparable getMaxValue()

Retrieve the maximum values values for this parameter or null if this is not specified

Returns:

hasDefaultValue

boolean hasDefaultValue()

Discover wether this parameter has a default value specified

Returns:

true when a default value is specified or false otherwise

hasLegalValues

boolean hasLegalValues()

Discover wether this parameter has legal values specified

Returns:

true when the legal values are specified or false otherwise

hasMinValue

boolean hasMinValue()

isValue

boolean isValue(Object obj)

Tests whether an object is acceptable as a paramter value

Parameters:

obj - the object to test

Returns:

true when it is a valid value, or false otherwise

equals

boolean equals(Object obj)

Compares an object for equality with the implementing class.

The object is not null
The object implements the open mbean attribute info interface
The parameter names are equal
The open types are equal
The default, min, max and legal values are equal

Overrides:

equals in class Object

Parameters:

obj - the object to test

Returns:

true when above is true, false otherwise

hashCode

int hashCode()

Generates a hashcode for the implementation.

The sum of the hashCodes for the elements mentioned in the equals method

Overrides:

hashCode in class Object

Returns:

the calculated hashcode

toString

String toString()

A string representation of the open mbean parameter info.

It is made up of implementation class and the values mentioned in the equals method

Overrides:

toString in class Object

Returns:

the string
