Method Detail

setRuntime

public void setRuntime(org.jruby.Ruby runtime)

Description copied from interface: JRubyInvoker

Not required, however if set, the invoker will tear down the runtime before exiting Invoke. If you plan on changing the state of inkove-returned IRubyObjects, you should set this externally via Ruby.getDefaultInstance(), and tear it down when done via tearDown() method.

Specified by:

setRuntime in interface JRubyInvoker

setReader

public void setReader(java.io.Reader reader)

The sole way of sending a script to this invoker object.

Specified by:

setReader in interface JRubyInvoker

Parameters:

reader -

setAssumeLoop

public void setAssumeLoop(boolean assumeLoop)

As per the Ruby command line arg -n.

Specified by:

setAssumeLoop in interface JRubyInvoker

Parameters:

assumeLoop -

setAssumePrintLoop

public void setAssumePrintLoop(boolean assumePrintLoop)

As per the Ruby command line arg -p.

Specified by:

setAssumePrintLoop in interface JRubyInvoker

Parameters:

assumePrintLoop -

setAutoSplit

public void setAutoSplit(boolean autoSplit)

As per the Ruby command line arg -a.

Specified by:

setAutoSplit in interface JRubyInvoker

Parameters:

autoSplit -

setWarning

public void setWarning(int warning)

As per the Ruby command line arg -W#.

Specified by:

setWarning in interface JRubyInvoker

Parameters:

warning -

setDebug

public void setDebug(boolean debug)

As per the Ruby command line arg -d. (sets $DEBUG to true)

Specified by:

As per the Ruby command line arg -l.

Specified by:

setProcessLineEnds in interface JRubyInvoker

Parameters:

processLineEnds -
