Inspecting Properties

This topic describes how to use Tcl commands to get properties values for an object and items in a set.

Get a Property Value for an Object

Two commands, inspect_getprop and ip (shorthand for inspect_prop) can be used to get the property value for an object.

inspect_getprop -prop_name s_propName -object d_ctuObj

and

ip s_propName d_ctubobj

are equivalent in function.

For example, both of the following commands return the name of the net given by the $net variable:

• inspect_getprop -prop_name name -object $net
• ip name $net

Get a Property Value for Items in a Set

To get a property value for an item in a set, use one of the following:

• inspect_getprop -prop_name s_propName -item i_itemNbr -set d_setObj
• ip s_propName [lindex [ml d_setObj] [i_itemNbr-1]]

The following examples return the type property value for the first object in the set given by the iSet variable.

• inspect_getprop -prop_name type -item 1 -set $iSet
• ip type [lindex [ml $iSet] 0]

By default, inspect_getprop operates on the selected set, if not empty, and -item must be given if there is more than one object in the set.
