Fabian Hueske created FLINK-7291: ------------------------------------ Summary: Incorrect return value of getArity() in ListTypeInfo and MapTypeInfo Key: FLINK-7291 URL: https://issues.apache.org/jira/browse/FLINK-7291 Project: Flink Issue Type: Bug Components: Core Affects Versions: 1.3.1, 1.4.0 Reporter: Fabian Hueske
The implementation of {{getArity()}} in {{ListTypeInfo}} and {{MapTypeInfo}} returns 0 but should return 1. The JavaDocs of {{TypeInformation.getArity()}} should be extended as well to avoid future confusion about this method. The method returns the arity for current type. For atomic types, this is 1 for composite types, the number of non-nested fields (or number of fields on the first nesting-level). -- This message was sent by Atlassian JIRA (v6.4.14#64029)
