    This function can't be called in read-only mode.

    Throws

    Throws an exception if the command fails due to incorrect parameters or command syntax, or in erroneous cases for the command. Note that in many cases, if the command does not operate (e.g., a target selector found no matches), this method will not throw an exception.

    CommandError

  • Parameters

    Throws

    Throws an exception if the command fails due to incorrect parameters or command syntax, or in erroneous cases for the command. Note that in many cases, if the command does not operate (e.g., a target selector found no matches), this method will not throw an exception.
