Field Detail

lineSep

private final java.lang.String lineSep

Constructor Detail

Empty

public Empty(java.lang.String lineSep)

ctor

Parameters:

lineSep - null or "", then an empty line will be output. contains one character, then this character is repeated till the current length of all other lines. contains a longer String: Writes this string as separation line.

Method Detail

registerLines

public void registerLines()

Specified by:

registerLines in class TestSignalRecorder

addSignals

public int addSignals(int time,
                      int lenCurr,
                      boolean bAdd)
               throws java.io.IOException

This operation is empty, does nothing, returns 0, no contribution for presentation.

Specified by:

addSignals in class TestSignalRecorder

Parameters:

time - the system time may be used for output

lenCurr - the current length of the StringBuilder lines before adding for this timestamp. This parameter can be used for TestSignalRecorder.checkLen(StringBuilder, int).

bAdd - true then other TestSignalsRecorders have added an information in this step time before. This information can be used to decide whether to add. But it depends on the order of registering in TestSignalRecorderSet.registerRecorder(TestSignalRecorder). If you want to use this function, this test generator is subordinate, it accepts the behavior of the recorders before delivered in the return value of this operation. If the return value of all called before addSignals(...) operation is 0, then this value is false on usage of TestSignalRecorderSet.addSignals(int).

Returns:

0 if no signal is added. Elsewhere the length of the longest yet written internal buffer.

Throws:

java.io.IOException

output

public void output(java.lang.Appendable out)
            throws java.io.IOException

Description copied from class: TestSignalRecorder

This operation outputs all lines. Special function: If no lines are registered, an empty line is outputted. This can be used to structure the output.

Overrides:

output in class TestSignalRecorder

Throws:

java.io.IOException
