OutputStreamAwkSink

public OutputStreamAwkSink(OutputStream outputStream)

Creates a sink backed by an OutputStream.

Parameters:

outputStream - stream that should receive AWK output

OutputStreamAwkSink

public OutputStreamAwkSink(OutputStream outputStream,
 Locale locale)

Creates a sink backed by an OutputStream.

Parameters:

outputStream - stream that should receive AWK output

locale - locale used for numeric formatting

OutputStreamAwkSink

public OutputStreamAwkSink(PrintStream printStream)

Creates a sink backed directly by a PrintStream.

Parameters:

printStream - stream that should receive AWK output

OutputStreamAwkSink

public OutputStreamAwkSink(PrintStream printStream,
 Locale locale)

Creates a sink backed directly by a PrintStream.

Parameters:

printStream - stream that should receive AWK output

locale - locale used for numeric formatting

Method Details

print

public void print(String ofs,
 String ors,
 String ofmt,
 Object... values)

Description copied from class: AwkSink

Writes one AWK print operation.

Specified by:

print in class AwkSink

Parameters:

ofs - output field separator

ors - output record separator

ofmt - numeric output format used by plain print

values - values supplied to print

printf

public void printf(String ofs,
 String ors,
 String ofmt,
 String format,
 Object... values)

Description copied from class: AwkSink

Writes one AWK printf operation.

Specified by:

printf in class AwkSink

Parameters:

ofs - output field separator

ors - output record separator

ofmt - numeric output format available to the sink

format - format string passed to printf

values - arguments supplied after the format string

flush

public void flush()

Description copied from class: AwkSink

Flushes any buffered output held by this sink.

Overrides:

flush in class AwkSink

getPrintStream

public PrintStream getPrintStream()

Description copied from class: AwkSink

Returns a PrintStream view that receives raw process output written by spawned commands such as system("...").

The default implementation returns a stream that silently discards all output. Override this method in sinks that need to capture process output.

Overrides:

getPrintStream in class AwkSink

Returns:

print stream that should receive raw process output
