Method Detail

estimateParsedLength

public int estimateParsedLength()

Description copied from interface: InternalParser

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

Specified by:

estimateParsedLength in interface InternalParser

Returns:

the estimated length

parseInto

public int parseInto(DateTimeParserBucket bucket,
                     java.lang.CharSequence text,
                     int position)

Description copied from interface: InternalParser

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.

Specified by:

parseInto in interface InternalParser

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
