Examples of com.google.gxp.compiler.schema.AttributeValidator

com.google.gxp.compiler.schema.AttributeValidator

Schema component which represents an XML attribute. SchemaParser creates these out of <attribute> elements.
Each AttributeValidator corresponds to a single type of attribute. Note that unlike elements and doctypes, there can be multiple attributes in the same schema that have the same name. If two attributes have the same name they must not be attached to the same ElementValidator.
AttributeValidators are retrieved via {@link ElementValidator#getAttributeValidator(String)}.

              newAttrBuilder.put(name, updatedAttr);
              return null;
            }


            public Void visitBundleType(BundleType type) {
              final AttributeValidator validator = type.getValidator(name);
              String innerContentTypeString = validator.getContentType();
              if (innerContentTypeString != null) {
                Schema innerSchema = schemaFactory.fromContentTypeName(innerContentTypeString);
                attrBundles.get(parameter.getPrimaryName()).put(validator,
                                                         updatedAttr.withInnerSchema(innerSchema));
