Constructor Detail

ValueLabel

public ValueLabel(long value,
                  String unit)

Creates a value label with the given base value and unit. For example:

 ValueLabel bits = new ValueLabel(2_050, "b");
 ValueLabel bytesPs = new ValueLabel(3_000_000, "B").perSec();
 

Generating labels:

   bits.toString()     ...  "2.00 Kb"
   bytesPs.toString()  ...  "2.86 MBps"
 

Parameters:

value - the base value

unit - the value unit

Method Detail

perSec

public TopoUtils.ValueLabel perSec()

Mark this value to be expressed as a rate. That is, "ps" (per sec) will be appended in the string representation.

Returns:

self, for chaining

clipG

public TopoUtils.ValueLabel clipG(double threshold)

Clips the (adjusted) value to the given threshold expressed in Giga units. That is, if the adjusted value exceeds the threshold, it will be set to the threshold value and the clipped flag will be set. For example,

 ValueLabel tooMuch = new ValueLabel(12_000_000_000, "b")
      .perSec().clipG(10.0);

 tooMuch.toString()    ...  "10.00 Gbps"
 tooMuch.clipped()     ...  true
 

Parameters:

threshold - the clip threshold (Giga)

Returns:

self, for chaining

clipped

public boolean clipped()

Returns true if this value was clipped to a maximum threshold.

Returns:

true if value was clipped

magnitude

public TopoUtils.Magnitude magnitude()

Returns the magnitude value.

Returns:

the magnitude

toString

public String toString()

Overrides:

toString in class Object
