Enclosing class:

CsvSchema

public static class CsvSchema.Builder
extends Object

Class used for building CsvSchema instances.

Field Summary

protected String	_anyPropertyName If "any properties" (properties for 'extra' columns; ones not specified in schema) are enabled, they are mapped to this name: leaving it as null disables use of "any properties" (and they are either ignored, or an exception is thrown, depending on other settings); setting it to a non-null String value will expose all extra properties under one specified name.
protected String	_arrayElementSeparator
protected ArrayList<CsvSchema.Column>	_columns
protected char	_columnSeparator
protected int	_encodingFeatures Bit-flag for general-purpose on/off features.
protected int	_escapeChar
protected char[]	_lineSeparator
protected char[]	_nullValue
protected int	_quoteChar

Constructor Summary

CsvSchema.Builder()

CsvSchema.Builder(CsvSchema src)
