Description

Provides accessors for expressions.

This module wraps the expressions derived from suite.Expression using the classes corresponding to the XSCADE serialization, as exposed in the SCADE documentation: SCADE Suite Metamodels for Java API > 12. Scade Language Metamodels > Expressions. These classes allow accessing precisely each member of an expression.

Use the accessor() function to create an accessor from any SCADE Suite expression.
