Interface ReadOptions.ColumnTypeReadOptions

Enclosing class:

ReadOptions

public static interface ReadOptions.ColumnTypeReadOptions

Allows user to set column types. It can work in three ways:

• If no information is provided column types are autodetected
• A complete list of columns can be provided using ReadOptions.Builder.columnTypes(ColumnType[]) or ReadOptions.Builder.columnTypes(Function). This skips column type detection.
• Provide values for some column names using ReadOptions.Builder.columnTypesPartial(Map) or ReadOptions.Builder.columnTypesPartial(Function) (String, ColumnType)}. In this case provided columnTypes are used and the others are autodetected
