package org.joda.time.format;

Internal interface for parsing textual representations of datetimes.

Application users will rarely use this class directly. Instead, you will use one of the factory classes to create a DateTimeFormatter.

The factory classes are:
- DateTimeFormatterBuilder
- DateTimeFormat
- ISODateTimeFormat

public interface DateTimeParser {

    
Returns the expected maximum number of characters consumed. The actual amount should rarely exceed this estimate.

Returns:
the estimated length
    int estimateParsedLength();

    
Parse an element from the given text, saving any fields into the given DateTimeParserBucket. If the parse succeeds, the return value is the new text position. Note that the parse may succeed without fully reading the text.

If it fails, the return value is negative. To determine the position where the parse failed, apply the one's complement operator (~) on the return value.

Parameters:
bucket field are saved into this, not null
text the text to parse, not null
position position to start parsing from
Returns:
new position, negative value means parse failed - apply complement operator (~) to get position of failure
Throws:
java.lang.IllegalArgumentException if any field is out of range
    int parseInto(DateTimeParserBucket bucketString textint position);
