    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
```
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:

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. *
