Class LineProcessors

java.lang.Object

org.netbeans.api.extexecution.base.input.LineProcessors

public final class LineProcessors
extends Object

Factory methods for LineProcessor classes.

Note that main difference between InputProcessor and LineProcessor is that LineProcessor always process whole lines.

Method Summary

Modifier and Type	Method and Description
static LineProcessor	patternWaiting(Pattern pattern, CountDownLatch latch) Returns the processor that will wait for the line matching the pattern, decreasing the latch when such line appears for the first time.
static LineProcessor	printing(PrintWriter out) Returns the processor printing all lines passed for processing to the given output writer.
static LineProcessor	proxy(LineProcessor... processors) Returns the processor acting as a proxy.

Method Detail

proxy

@NonNull
public static LineProcessor proxy(@NonNull
                                           LineProcessor... processors)

Returns the processor acting as a proxy.

Any action taken on this processor is distributed to all processors passed as arguments in the same order as they were passed to this method.

Returned processor is not thread safe.

Parameters:

processors - processor to which the actions will be distributed

Returns:

the processor acting as a proxy

printing

@NonNull
public static LineProcessor printing(@NonNull
                                              PrintWriter out)

Returns the processor printing all lines passed for processing to the given output writer.

Processor closes the output writer on InputProcessor.close().

Returned processor is not thread safe.

Parameters:

out - where to print received lines

Returns:

the processor printing all lines passed for processing to the given output writer

patternWaiting

@NonNull
public static LineProcessor patternWaiting(@NonNull
                                                    Pattern pattern,
                                                    @NonNull
                                                    CountDownLatch latch)

Returns the processor that will wait for the line matching the pattern, decreasing the latch when such line appears for the first time.

Reset action on the returned processor is noop.

Returned processor is thread safe.

Parameters:

pattern - pattern that line must match in order decrease the latch

latch - latch to decrease when the line matching the pattern appears for the first time

Returns:

the processor that will wait for the line matching the pattern, decreasing the latch when such line appears for the first time
