Examples of org.apache.openjpa.jdbc.meta.ClassMappingInfo

org.apache.openjpa.jdbc.meta.ClassMappingInfo
Information about the mapping from a class to the schema, in raw form. The columns and tables used in mapping info will not be part of the {@link SchemaGroup} used at runtime. Rather, they will be structswith the relevant pieces of information filled in. @author Abe White

        String val = attrs.getValue("strategy");
        if (val == null)
            return true;


        ClassMapping cm = (ClassMapping) currentElement();
