Activities can access two types of arguments that are not directly
defined as properties:
- Parameters are formally declared input or output variables
that are passed to or from a called activity using a page structure.
This page has no class and is known as the parameter page.
- Local variables are text strings stored in a Java
StringBuffer object rather than a page structure. They require less
memory and can be accessed with less computer overhead than
parameters. Three special StringBuffer methods are available to
manipulate local variables.
Within the activity, use the Local
keyword followed by a
period and the variable name to read or set the value of a local
variable:
Local.Numberofcylinders
