    • addClassFilter

      void addClassFilter(ReferenceType refType)
      Restricts 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.

    • addClassFilter

      void addClassFilter(String classPattern)
      Restricts 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.

    • addClassExclusionFilter

      void addClassExclusionFilter(String classPattern)
      Restricts 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.

    • 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.
