Method Detail

parseToMap

Parse a String into a Map. The result can be null which means the given input string will be ignored.

parseToMap 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>

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.
