Interface IJavaWatchpoint

All Superinterfaces:: IAdaptable, IBreakpoint, IJavaBreakpoint, IJavaLineBreakpoint, ILineBreakpoint, IWatchpoint

public interface IJavaWatchpoint
extends IJavaLineBreakpoint, IWatchpoint
extends IJavaLineBreakpoint, IWatchpoint

A breakpoint on a field. If a watchpoint is an access watchpoint, it will suspend execution when its field is accessed. If a watchpoint is a modification watchpoint, it will suspend execution when its field is modified.

Since 3.1, IJavaWatchpoint also implements IWatchpoint.

Since:: 2.0

getFieldName


String getFieldName()
                    throws 
CoreException

Returns the name of the field associated with this watchpoint

Returns:: field the name of the field on which this watchpoint is installed
Throws:: CoreException - if unable to access the property on this breakpoint's underlying marker

isAccessSuspend

boolean isAccessSuspend(
IDebugTarget target)

Returns whether this breakpoint last suspended in this target due to an access (true) or modification (false).

Returns:: true if this watchpoint last suspended the given target due to a field access; false if this watchpoint last suspended the given target due to a modification access or if this watchpoint hasn't suspended the given target.
