Class DelimitedWriter

java.lang.Object
  org.beanio.stream.delimited.DelimitedWriter

All Implemented Interfaces:

RecordWriter

public class DelimitedWriter
extends Object
implements RecordWriter

A DelimitedWriter is used to write records to delimited flat files. Each record must be a String array of fields. By default, fields are delimited by the tab character, but any other single character may be configured instead.

If an escape character is configured, any field containing the delimiter will be escaped by placing the escape character immediately before the delimiter. For example, if the record "Field1,2", "Field3" is written using a comma delimiter and backslash escape character, the following text will be written to the output stream:

 Field1\,2,Field3
 

Note that no validation is performed when a record is written, so if an escape character is not configured and a field contains a delimiting character, the generated output may be invalid.
