setEnabled

public void setEnabled(boolean enabled)

Specified by:
setEnabled in interface IBreakpoint
Parameters:
enabled - whether this breakpoint should be enabled
Throws:
CoreException - if unable to set the associated attribute on this breakpoint's underlying marker.
See Also:
IBreakpoint.setEnabled(boolean)

isEnabled

public boolean isEnabled()
                  throws 
CoreException
Description copied from interface: IBreakpoint
Returns whether this breakpoint is enabled

Specified by:
isEnabled in interface IBreakpoint
Returns:
whether this breakpoint is enabled
Throws:

See Also:
IBreakpoint.isEnabled()

isRegistered

public boolean isRegistered()
                     throws 
CoreException
Description copied from interface: IBreakpoint
Returns whether this breakpoint is currently registered with the breakpoint manager.

Specified by:
isRegistered in interface IBreakpoint
Returns:
whether this breakpoint is currently registered with the breakpoint manager
Throws:
CoreException - if unable to access the associated attribute on this breakpoint's underlying marker
See Also:
IBreakpoint.isRegistered()

setRegistered

public void setRegistered(boolean registered)
                   throws 
CoreException
Description copied from interface: IBreakpoint
Sets whether this breakpoint is currently registered with the breakpoint manager.

Specified by:
setRegistered in interface IBreakpoint
Parameters:
registered - whether this breakpoint is registered with the breakpoint manager
Throws:
CoreException - if unable to set the associated attribute on this breakpoint's underlying marker.
See Also:
IBreakpoint.setRegistered(boolean)

delete

public void delete()
            throws 
CoreException
Description copied from interface: IBreakpoint
Deletes this breakpoint's underlying marker, and removes this breakpoint from the breakpoint manager.

Specified by:
delete in interface IBreakpoint
Throws:
CoreException - if unable to delete this breakpoint's underlying marker
See Also:
IBreakpoint.delete()

getMarker

public 
IMarker getMarker()
Description copied from interface: IBreakpoint
Returns the marker associated with this breakpoint, or null if no marker is associated with this breakpoint.

Specified by:
getMarker in interface IBreakpoint
Returns:
associated marker, or null if there is no associated marker.
See Also:
IBreakpoint.getMarker()

isPersisted

public boolean isPersisted()
                    throws 
CoreException
Description copied from interface: IBreakpoint
Returns whether this breakpoint is to be persisted across workspace invocations, or when a project is closed and re-opened. Since marker definitions only allow all/none of a specific type of marker to be persisted (rather than selected markers of a specific type), breakpoints define this functionality.

Specified by:
isPersisted in interface IBreakpoint
Returns:
whether this breakpoint is to be persisted
Throws:
CoreException - if unable to access the associated attribute on this breakpoint's underlying marker
See Also:
IBreakpoint.isPersisted()

setPersisted

public void setPersisted(boolean persisted)
                  throws 
CoreException
Description copied from interface: IBreakpoint
Sets whether this breakpoint is to be persisted across workspace invocations, or when a project is closed and re-opened. Has no effect if this breakpoint's marker definition is defined as not persisted. Sets the underlying TRANSIENT attribute on this breakpoint's marker to true.

Specified by:
setPersisted in interface IBreakpoint
Parameters:
persisted - whether this breakpoint is to be persisted across workspace invocations
Throws:
CoreException - if unable to set the associated attribute on this breakpoint's underlying marker.
See Also:
IBreakpoint.setPersisted(boolean)
