Class P4HandlerAdapter

java.lang.Object
  |
  +--org.apache.tools.ant.taskdefs.optional.perforce.P4HandlerAdapter

All Implemented Interfaces:

ExecuteStreamHandler, P4Handler

Direct Known Subclasses:

SimpleP4OutputHandler

public abstract class P4HandlerAdapter

extends java.lang.Object

implements P4Handler

base class to manage streams around the execution of the Perforce command line client

Constructor Summary

P4HandlerAdapter()

Method Summary

abstract void	process(java.lang.String line) subclasses of P4HandlerAdapter must implement this routine processing of one line of stdout or of stderr
void	setOutput(java.lang.String p4Input) set any data to be written to P4's stdin
void	setProcessErrorStream(java.io.InputStream is) connects the handler to the stderr of the Perforce process
void	setProcessInputStream(java.io.OutputStream os) connects the handler to the input stream into Perforce used indirectly by tasks requiring to send specific standard input such as p4label, p4change
void	setProcessOutputStream(java.io.InputStream is) connects the handler to the stdout of the Perforce process
void	start() this routine gets called by the execute routine of the Execute class it connects the PumpStreamHandler to the input/output/error streams of the process.
void	stop() stops the processing of streams called from P4Base#execP4Command(String command, P4Handler handler)

P4HandlerAdapter

public P4HandlerAdapter()

Method Detail

setOutput

public void setOutput(java.lang.String p4Input)

set any data to be written to P4's stdin

Specified by:

setOutput in interface P4Handler

Parameters:

p4Input - the text to write to P4's stdin

process

public abstract void process(java.lang.String line)

subclasses of P4HandlerAdapter must implement this routine processing of one line of stdout or of stderr

Specified by:

process in interface P4Handler

Parameters:

line - line of stdout or stderr to process

start

public void start()
           throws BuildException

this routine gets called by the execute routine of the Execute class it connects the PumpStreamHandler to the input/output/error streams of the process.

Specified by:

start in interface ExecuteStreamHandler

Throws:

BuildException

See Also:

Execute.execute()

stop

public void stop()

stops the processing of streams called from P4Base#execP4Command(String command, P4Handler handler)

Specified by:

stop in interface ExecuteStreamHandler

See Also:

P4Base.execP4Command(String, P4Handler)

setProcessInputStream

public void setProcessInputStream(java.io.OutputStream os)
                           throws java.io.IOException

connects the handler to the input stream into Perforce used indirectly by tasks requiring to send specific standard input such as p4label, p4change

Specified by:

setProcessInputStream in interface ExecuteStreamHandler

Parameters:

os - the stream bringing input to the p4 executable

Throws:

java.io.IOException - under unknown circumstances

setProcessErrorStream

public void setProcessErrorStream(java.io.InputStream is)
                           throws java.io.IOException

connects the handler to the stderr of the Perforce process

Specified by:

setProcessErrorStream in interface ExecuteStreamHandler

Parameters:

is - stderr coming from Perforce

Throws:

java.io.IOException - under unknown circumstances

setProcessOutputStream

public void setProcessOutputStream(java.io.InputStream is)
                            throws java.io.IOException

connects the handler to the stdout of the Perforce process

Specified by:

setProcessOutputStream in interface ExecuteStreamHandler

Parameters:

is - stdout coming from Perforce

Throws:

java.io.IOException - under unknown circumstances
