Public Methods
public String getBaseName ()
Returns the base name of this instrumentation object. The base name is the component of the name following the last "." character in the name.
Returns
- String - the base name of the name assigned to this instrumentation monitoring object.
public String getName ()
Returns the name of this instrumentation object.
Returns
- String - the name assigned to this instrumentation monitoring object
public Units getUnits ()
Returns the Units for this instrumentation monitoring object.
Returns
- Units - the units of measure attribute
public abstract Object getValue ()
Return an Object that encapsulates this instrumentation object's current data value.
public Variability getVariability ()
Returns the Variability for this instrumentation object.
Returns
- Variability - the variability attribute
public int getVectorLength ()
Return the length of the vector.
Returns
- int - the length of the vector or zero if this instrumentation object is a scalar type.
public boolean isSupported ()
Test if the instrumentation object is supported.
public boolean isVector ()
Test if the instrumentation object is a vector type.
Returns
- boolean - true if this instrumentation object is a vector type, false otherwise.
