? StatusVariable
java.lang.Object
org.osgi.service.monitor.StatusVariable
A
StatusVariable
object represents the value of a status variable
taken with a certain collection method at a certain point of time. The type
of the StatusVariable
can be int
, float
,
boolean
or String
.
A StatusVariable
is identified by an ID string that is unique within
the scope of a Monitorable
. The ID must be a non- null
,
non-empty string that conforms to the "symbolic-name" definition in the OSGi
core specification. This means that only the characters [-_.a-zA-Z0-9] may be
used. The length of the ID must not exceed 32 bytes when UTF-8 encoded.

getCollectionMethod
public int getCollectionMethod()Returns the collection method of thisStatusVariable
. See section 3.3 b) in [ETSI TS 132 403]- ??:
- one of the
CM_
constants
-
equals
Compares the specified object with thisStatusVariable
. TwoStatusVariable
objects are considered equal if their full path, collection method and type are identical, and the data (selected by their type) is equal. -
hashCode
public int hashCode()Returns the hash code value for thisStatusVariable
. The hash code is calculated based on the full path, collection method and value of theStatusVariable
. -
toString
Returns aString
representation of thisStatusVariable
. The returnedString
contains the full path, collection method, timestamp, type and value parameters of theStatusVariable
in the following format:StatusVariable(<path>, <cm>, <timestamp>, <type>, <value>)
The collection method identifiers used in the string representation are "CC", "DER", "GAUGE" and "SI" (without the quotes). The format of the timestamp is defined by theDate.toString
method, while the type is identified by one of the strings "INTEGER", "FLOAT", "STRING" and "BOOLEAN". The final field contains the string representation of the value of the status variable.
