Overrides:

maxCharsPerColumn in class ReadOptions.Builder

lineEnding

public FixedWidthReadOptions.Builder lineEnding(String lineEnding)

systemLineEnding

public FixedWidthReadOptions.Builder systemLineEnding()

padding

public FixedWidthReadOptions.Builder padding(char padding)

columnTypes

public FixedWidthReadOptions.Builder columnTypes(ColumnType[] columnTypes)

Description copied from class: ReadOptions.Builder

Provide column types for all columns skipping autodetect column type logic. The array must contain a ColumnType for each column in the table. An error will be thrown if they don't match up

Overrides:

columnTypes in class ReadOptions.Builder

columnTypes

public FixedWidthReadOptions.Builder columnTypes(Function<String,ColumnType> columnTypeFunction)

Description copied from class: ReadOptions.Builder

Provide a function that determines ColumnType for all column names. To provide only for some use ReadOptions.Builder.columnTypesPartial(Function)

This method is generally more efficient because it skips column type detection

Overrides:

columnTypes in class ReadOptions.Builder

columnTypesPartial

public FixedWidthReadOptions.Builder columnTypesPartial(Function<String,Optional<ColumnType>> columnTypeFunction)

Description copied from class: ReadOptions.Builder

Provide a function that determines ColumnType for some column names. To provide for all column names use ReadOptions.Builder.columnTypes(Function) that generally is more efficient because it skips column type detection

Overrides:

columnTypesPartial in class ReadOptions.Builder

columnTypesPartial

public FixedWidthReadOptions.Builder columnTypesPartial(Map<String,ColumnType> columnTypeByName)

Description copied from class: ReadOptions.Builder

Provide a map that determines ColumnType for given column names. Types for not present column names will be autodetected. To provide type for all column names use ReadOptions.Builder.columnTypes(Function) that generally is more efficient because it skips column type detection

Overrides:

columnTypesPartial in class ReadOptions.Builder

maxNumberOfColumns

public FixedWidthReadOptions.Builder maxNumberOfColumns(Integer maxNumberOfColumns)

Defines maximal value of columns in fixed-width file.

Parameters:

maxNumberOfColumns - - must be positive integer. Default is 512. *
