This module selects a specified object from #!F-adobe-times-bold-r-normal--18* input #!EF and
passes it through to #!F-adobe-times-bold-r-normal--18* output #!EF . #!N #!I0 #!N
#!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* selector #!EF #!EF #!I50 #!N specifies
which of the #!F-adobe-times-medium-i-normal--18* n #!EF input objects are to be
passed to #!F-adobe-times-bold-r-normal--18* output #!EF . If the specified value is
1, the first #!F-adobe-times-bold-r-normal--18* input #!EF object (the second input to
the module itself) is passed through; if the specified value is
2, the second input object (the third input to the module)
is passed through; and so on. #!N #!N If the specified
value is 0 or larger than #!F-adobe-times-medium-i-normal--18* n #!EF ,
#!F-adobe-times-bold-r-normal--18* output #!EF is NULL. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* input
#!EF #!EF #!I50 #!N specifies an input that may or may
not be passed to output. #!I0 #!N #!N A single Switch
module can accept a maximum of 21 input objects. In the
user interface, the default number of enabled tabs is two. (Tabs
can be added to the module icon and removed with the
appropriate #!F-adobe-times-bold-r-normal--18* ...Input Tab #!EF options in the #!F-adobe-times-bold-r-normal--18* Edit #!EF
pull-down menu of the VPE.) Note: In the user interface you
may find it helpful to use the first output of the
Selector interactor as the first input ( #!F-adobe-times-bold-r-normal--18* selector #!EF )
to Switch. See #!Lselint,dxall430 h Selector and SelectorList Interactors #!EL in IBM Visualization Data Explorer User's Guide
