Class ParserIterator<T>

java.lang.Object

com.univocity.parsers.common.iterators.ParserIterator<T>

All Implemented Interfaces:

IterableResult<T,ParsingContext>, java.lang.Iterable<T>

Direct Known Subclasses:

RecordIterator, RowIterator

abstract class ParserIterator<T>
extends java.lang.Object
implements IterableResult<T,ParsingContext>

An Iterator over the parser enabling easy iteration against rows and records Multiple iterations are possible if Files are being fed into the parser, but other forms of input (such as InputStreams and Readers) can not be iterated over more than once.

Field Detail

parser

protected final AbstractParser parser

Constructor Detail

ParserIterator

protected ParserIterator(AbstractParser parser)

Creates a ParserIterator using the provided parser

Parameters:

parser - the parser to iterate over

Method Detail

getContext

public final ParsingContext getContext()

Description copied from interface: IterableResult

Returns the current parsing Context, if available

Specified by:

getContext in interface IterableResult<T,ParsingContext>

Returns:

the contextual object with information about an ongoing parsing process

beginParsing

protected abstract void beginParsing()

This method is called whenever the iterator is starting to iterate over the results. an example implementation of this is:

     
     @Override
     public void beginParsing(){
         parser.beginParsing(input);
     }
 

This is to allow for different input types such as Reader, File, or InputStream without large code reuse.

iterator

public final ResultIterator<T,ParsingContext> iterator()

Specified by:

iterator in interface IterableResult<T,ParsingContext>

Specified by:

iterator in interface java.lang.Iterable<T>

nextResult

protected abstract T nextResult()

Returns the next record (either a String[] or a Record)

Returns:

the next record if available.
