Subject [jira] [Updated] (FLINK-9502) Use generic parameter search for user-define functions when argument contains Object type
Date Tue, 05 Jun 2018 17:46:00 GMT

     [ https://issues.apache.org/jira/browse/FLINK-9502?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rong Rong updated FLINK-9502:
-----------------------------
    Description: 
This ticket is to enable generic Object type as element type by using SQL ANY in parameter
/ argument type mapping.
This will enable support for use case such as:
{code:java}
public String eval(Object objArg) { // ... }
{code}

The changes require here:
1. Introduce wildcard search and search rules for SQL ANY type usage.
2. Enabling wildcard search when concrete type search returns no match.
