Example 1 with ConstructorReference

use of cn.taketoday.expression.spel.ast.ConstructorReference in project today-framework by TAKETODAY.

the class InternalSpelExpressionParser method maybeEatConstructorReference.

            // looks like 'NEW]' (so NEW used as map key)
            push(new PropertyOrFieldReference(false, newToken.stringValue(), newToken.startPos, newToken.endPos));
