Method Detail

ROW

public static RowTypeInfo ROW(TypeInformation<?>... types)

Generates a RowTypeInfo with fields of the given types. The fields have the default names (f0, f1, f2 ..).

This method is a shortcut to new RowTypeInfo(types).

Parameters:

types - The types of the row fields, e.g., Types.STRING, Types.INT

ROW_NAMED

public static RowTypeInfo ROW_NAMED(String[] fieldNames,
                                    TypeInformation<?>... types)

Generates a RowTypeInfo with fields of the given types and with given names.

Example use: ROW_NAMED(new String[]{"name", "number"}, Types.STRING, Types.INT).

This method is identical to new RowTypeInfo(types, names).

Parameters:

fieldNames - array of field names

types - array of field types
