Method Detail

getDelimiter

public String getDelimiter()

getListDelimiter

public String getListDelimiter()

getFieldNames

public List<String> getFieldNames()

Description copied from interface: Parser

Returns the fieldNames that we expect to see in parsed Maps, if known, or null otherwise. Deprecated; Parsers should not, in general, be expected to know what fields they will return.

Specified by:

getFieldNames in interface Parser<String,Object>

setFieldNames

public void setFieldNames(Iterable<String> fieldNames)

Description copied from interface: Parser

Set the fieldNames that you expect to see in parsed Maps. Deprecated; Parsers should not, in general, be expected to know what fields they will return. Some individual types of parsers do need to know (like a TSV parser) and those parsers have their own way of setting field names.

Specified by:

setFieldNames in interface Parser<String,Object>

setFieldNames

public void setFieldNames(String header)

parse

public Map<String,Object> parse(String input)

Description copied from interface: Parser

Parse a String into a Map.
