- All Superinterfaces:
- EventRequest,- Mirror
Request for notification when a step occurs in the target VM.
 When an enabled StepRequest is satisfied, an
 
event set containing a
 StepEvent will be placed on the
 EventQueue.
 The collection of existing StepRequests is
 managed by the EventRequestManager- Since:
- 1.3

addClassFilterRestricts the events generated by this request to those whose location is in the given reference type or any of its subtypes. An event will be generated for any location in a reference type that can be safely cast to the given reference type.- 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.
 
- 
addClassFilterRestricts the events generated by this request to those whose location is in a class whose name matches a 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.
 
- 
addClassExclusionFilterRestricts the events generated by this request to those whose location is in a class whose name does not match a 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 against.
- Throws:
- InvalidRequestStateException- if this request is currently enabled or has been deleted. Filters may be added only to disabled requests.
 
- 
addInstanceFilterRestricts 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.
