Local variable
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
