Method Detail

visit

public void visit(CelAbstractSyntaxTree ast)

Visit the ast value, routing to overloads based on the kind of expression.

visit

public void visit(CelExpr expr)

Visit the expr value, routing to overloads based on the kind of expression.

visit

protected void visit(CelExpr expr,
                     CelExpr.CelIdent ident)

Visit an CelIdent expression.

visit

protected void visit(CelExpr expr,
                     CelConstant constant)

Visit a CelConstant expression.

visit

protected void visit(CelExpr expr,
                     CelExpr.CelSelect select)

Visit a CelSelect expression.

visit

protected void visit(CelExpr expr,
                     CelExpr.CelCall call)

Visit a CelCall expression.

Arguments to the call are provided to the visitArg(dev.cel.common.ast.CelExpr, dev.cel.common.ast.CelExpr, int) function after they have been visited.

visit

protected void visit(CelExpr expr,
                     CelExpr.CelStruct struct)

Visit a CelStruct expression.

visit

protected void visit(CelExpr expr,
                     CelExpr.CelMap map)

Visit a CelMap expression.

visit

protected void visit(CelExpr expr,
                     CelExpr.CelList list)

Visit a CelList expression.

visit

protected void visit(CelExpr expr,
                     CelExpr.CelComprehension comprehension)

Visit a CelComprehension expression.

Arguments to the comprehension are provided to the visitArg(dev.cel.common.ast.CelExpr, dev.cel.common.ast.CelExpr, int) function after they have been visited.

visitArg

protected void visitArg(CelExpr expr,
                        CelExpr arg,
                        int argNum)

Visit the argument to an expression in the context of the calling expression.

For CelCall expressions, the arg num refers to the ordinal of the argument.

For CelComprehension expressions, the arg number refers to the ordinal of the enum value as it appears in CelExprVisitor.ComprehensionArg.
