Interface MonitorWaitedRequest

All Superinterfaces:
EventRequest, Mirror
public interface MonitorWaitedRequest extends EventRequest

" When an enabled MonitorWaitedRequest is satisfied, an event set containing a MonitorWaitedEvent will be placed on the EventQueue. The collection of existing MonitorWaitedEvents is managed by the EventRequestManager
Since:
1.6

Method Details

addThreadFilter

void addThreadFilter(ThreadReference thread)
Restricts the events generated by this request to those in the given thread.
Parameters:
thread - the thread to filter on.
Throws:
InvalidRequestStateException - if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.

addClassFilter

void addClassFilter(ReferenceType refType)
Restricts the events generated by this request to those whose monitor object is of the given reference type or any of its subtypes.
Parameters:
refType - the reference type to filter on.
Throws:
InvalidRequestStateException - if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.

addClassFilter

void addClassFilter(String classPattern)
Restricts the events generated by this request to those in which the name of the class of the monitor object matches this restricted regular expression. Regular expressions are limited to exact matches and patterns that begin with '*' or end with '*'; for example, "*.Foo" or "java.*".
Parameters:
classPattern - the pattern String to filter for.
Throws:
InvalidRequestStateException - if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.

addClassExclusionFilter

void addClassExclusionFilter(String classPattern)
Restricts the events generated by this request to those in which the name of the class of the monitor object does notmatch this restricted regular expression, e.g. "java.*" or "*.Foo".
Parameters:
classPattern - the pattern String to filter against.
Throws:
InvalidRequestStateException - if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.

addInstanceFilter

void addInstanceFilter(ObjectReference instance)
Restricts the events generated by this request to those in which the currently executing instance ("this") 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.
