Method Detail

latestLineMatches

boolean latestLineMatches(@Nonnull
                          String regexp)

Returns true if the latest received line matches the given regular expression.

Parameters:

regexp - the regular expression

Returns:

true in case of match

filteredBy

@Nonnull
List<String> filteredBy(@Nonnull
                        String regexp)

Returns a list of lines that match the given regular expression.

Parameters:

regexp - the regular expression

Returns:

the list of matching lines

filteredAndSplitBy

@Nonnull
Scanner filteredAndSplitBy(@Nonnull
                           String regexp,
                           @Nonnull
                           String delimiterRegexp)

Returns a Scanner over the latest line matching a given regular expression, with the specific delimiter regular expression.

Parameters:

regexp - the regular expression for the filter

delimiterRegexp - the regular expression for the Scanner

Returns:

the list of matching lines

waitFor

@Nonnull
ProcessExecutor.ConsoleOutput waitFor(@Nonnull
                                      String regexp)
                               throws InterruptedException,
                                      IOException

Waits for a line matching the given regular expression to appear.

Parameters:

regexp - the regular expression

Returns:

itself for chaining methods

Throws:

InterruptedException - if the wait has been interrupted

IOException - in case the process has terminated or another I/O error

clear

void clear()

Clears the buffer of lines. This means that no filtering or waiting operation can be performed on the output produced so far. It will be possible to perform further operations on the output produced from now on.

setListener

void setListener(@Nonnull
                 ProcessExecutor.ConsoleOutput.Listener listener)

Sets a listener.
