Method Detail

viewpointAdapt

public static JavaExpression viewpointAdapt(JavaExpression javaExpr,
                                            @Nullable List<JavaExpression> args)

Replace FormalParameters by args in javaExpr. (ThisReferences are not converted.)

Parameters:

javaExpr - the expression to viewpoint-adapt

args - the expressions that replace FormalParameters; if null, FormalParameters are not replaced

Returns:

the viewpoint-adapted expression

viewpointAdapt

public static JavaExpression viewpointAdapt(JavaExpression javaExpr,
                                            @Nullable JavaExpression thisReference)

Replace ThisReference with thisReference in javaExpr. (FormalParameter are not replaced.

Parameters:

javaExpr - the expression to viewpoint-adapt

thisReference - the expression that replaces occurrences of ThisReference; if null, ThisReferences are not replaced

Returns:

the viewpoint-adapted expression

viewpointAdapt
