All objects have properties and those properties can be inspected and referenced. An example of a property of an object might be its size or length. There are thousands of property inspectors available to cover the majority of software and hardware features of Windows, Mac, and UNIX systems.
These are different ways that you can use to list the properties of an object you can query using an inspector:
- Click Inspector Search, type the name of the inspector that you want to search and then the magnifying lens. In the list that you get, click the link to the inspector.
- Click Reference, navigate the area of interest that the inspector belongs to and then click the inspector name.
- Query the inspector, for example "string", from the Fixlet Debugger or the QnA tool using an introspector called "properties of type". This page explains how to use this introspector.
- Q: properties of type "string"
- A: sets of <string>: string set
- A: length of <string>: integer
- A: concatenations of <string>: string
- A: ....
