Parameters:

line - the line id to create the breakpoint on

dbg - the Debugger

LineBreakpoint

public LineBreakpoint(int lineIdx,
                      Debugger dbg)

Create a LineBreakpoint on a line in the current tab.

Parameters:

lineIdx - the line index of the current tab to create the breakpoint

Method Detail

lineID

public LineID lineID()

Get the line id this breakpoint is on.

isOnLine

public boolean isOnLine(LineID testLine)

Test if this breakpoint is on a certain line.

Parameters:

testLine - the line id to test

Returns:

true if this breakpoint is on the given line

attach

protected boolean attach(com.sun.jdi.ReferenceType theClass)

Attach this breakpoint to the VM. Creates and enables a BreakpointRequest. VM needs to be paused.

Parameters:

theClass - class to attach to

Returns:

true on success

isAttached

protected boolean isAttached()

detach

public void detach()

Detach this breakpoint from the VM. Deletes the BreakpointRequest.

set

protected void set()

Set this breakpoint. Adds the line highlight. If Debugger is paused also attaches the breakpoint by calling #attach().

toString in class Object

className

protected String className()

Get the name of the class this breakpoint belongs to. Needed for fetching the right location to create a breakpoint request.

Returns:

the class name

classLoaded

public void classLoaded(com.sun.jdi.ReferenceType theClass)

Event handler called when a class is loaded in the debugger. Causes the breakpoint to be attached, if its class was loaded.

Specified by:

classLoaded in interface ClassLoadListener

Parameters:

theClass - the class that was just loaded.

parseTopLevelClassName

public static String parseTopLevelClassName(String name)
