Method Detail

setDebugger

public void setDebugger(Debugger debugger)

Registers the specified debugger as the controller of this debug context

getDebugger

public Debugger getDebugger()

Returns the debugger that controls this debug context

open

protected void open(Function f,
                    java.lang.Object[] args)

Tracks stack depth (function call) in pure interpreter. This method overrides Context.open().

Overrides:

open in class Context

close

protected void close(Function f,
                     java.lang.Object[] args)

Tracks stack depth (function return) in pure interpreter. This method overrides Context.close().

Overrides:

close in class Context

getEvalDepth

public int getEvalDepth()

Get the depth of evaluation. This value increases when load(), loadFile(), or eval() is called.

getCallDepth

public int getCallDepth()

Get the stack depth (in pure interpreter)

getBeginLine

protected int getBeginLine()

getEndLine

protected int getEndLine()

getScriptSource

protected java.lang.Object getScriptSource()

Description copied from class: Context

Get the source of the script.

Overrides:

getScriptSource in class Context

Returns:

  java.net.URL object, when the script is not precompiled
  pnuts.lang.Runtime object, when the script is precompiled

 

updateLine

protected void updateLine(SimpleNode node,
                          int beginLine,
                          int beginColumn)

This method is called when line number is changed.

Overrides:

updateLine in class Context

Parameters:

node - the current AST node

beginLine - the line number at which the current expression starts.

beginColumn - the column number at which theh current expression ends.

onError

protected void onError(java.lang.Throwable t)

This method is called when some exception is thrown.

Overrides:

onError in class Context

onExit

protected void onExit(java.lang.Object arg)

This method is called when an evaluation is terminated normally.

Overrides:

onExit in class Context

addCommandListener

public void addCommandListener(CommandListener listener)

removeCommandListener

public void removeCommandListener(CommandListener listener)

clone

public java.lang.Object clone(boolean clear_attributes,
                              boolean clear_locals,
                              boolean clear_listeners)
