Field Detail

INVALID

public static final Units INVALID

An Invalid Units value.

NONE

public static final Units NONE

Units attribute representing unit-less quantities.

BYTES

public static final Units BYTES

Units attribute representing Bytes.

TICKS

public static final Units TICKS

Units attribute representing Ticks.

EVENTS

public static final Units EVENTS

Units attribute representing a count of events.

STRING

public static final Units STRING

Units attribute representing String data. Although not really a unit of measure, this Units value serves to distinguish String instrumentation objects from instrumentation objects of other types.

HERTZ

public static final Units HERTZ

Units attribute representing Hertz (frequency).

Method Detail

toString

public String toString()

Returns a string describing this Unit of measurement attribute

Overrides:

toString in class Object

Returns:

String - a descriptive string for this enum.

intValue

public int intValue()

Returns the integer representation of this Units attribute

Returns:

int - an integer representation of this Units attribute.

toUnits

public static Units toUnits(int value)

Maps an integer value to its corresponding Units attribute. If the integer value does not have a corresponding Units enum value, then INVALID is returned.

Parameters:

value - an integer representation of counter Units

Returns:

Units - the Units object for the given value or INVALID if out of range.
