-V Specifies if inverse of selection is to be output.
- 指定者:
setOptions
在接口中OptionHandler
- 参数:
options
- the list of options as an array of string.s- 抛出:

-
getInstancesIndices
Gets ranges of instances selected.- 返回:
- a string containing a comma-separated list of ranges
-
setInstancesIndices
Sets the ranges of instances to be selected. If provided string is null, ranges won't be used for selecting instances.- 参数:
