com.sun.jdi.request
Interface BreakpointRequest

All Superinterfaces:: EventRequest, Locatable, Mirror

public interface BreakpointRequest
extends EventRequest, Locatable
extends EventRequest, Locatable

Identifies a Location in the target VM at which execution should be stopped. When an enabled BreakpointRequest is satisfied, an event set containing an BreakpointEvent will be placed on the EventQueue and the application is interrupted. The collection of existing breakpoints is managed by the EventRequestManager

Since:: 1.3
See Also:: Location, BreakpointEvent, EventQueue, EventRequestManager

Method Detail

location

Location location()

Returns the location of the requested breakpoint.

Specified by:: location in interface Locatable

Returns:: the Location where this breakpoint has been set.

Restricts the events generated by this request to those in the given thread.

Parameters:: thread - the thread to filter on.

addInstanceFilter

void addInstanceFilter(ObjectReference instance)

Restricts the events generated by this request to those in which the currently executing instance is the object specified.

Not all targets support this operation. Use VirtualMachine.canUseInstanceFilters() to determine if the operation is supported.

Parameters:: instance - the object which must be the current instance in order to pass this filter.
Throws:: UnsupportedOperationException - if the target virtual machine does not support this operation.; InvalidRequestStateException - if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.
