Method Detail

print

public boolean print(DateTimePrintContext context,
                     java.lang.StringBuilder buf)

Description copied from interface: DateTimeFormatterBuilder.DateTimePrinterParser

Prints the date-time object to the buffer.

The context holds information to use during the print. It also contains the date-time information to be printed.

The buffer must not be mutated beyond the content controlled by the implementation.

Specified by:

print in interface DateTimeFormatterBuilder.DateTimePrinterParser

Parameters:

context - the context to print using, not null

buf - the buffer to append to, not null

Returns:

false if unable to query the value from the date-time, true otherwise

parse

public int parse(DateTimeParseContext context,
                 java.lang.CharSequence text,
                 int position)

This implementation looks for the longest matching string. For example, parsing Etc/GMT-2 will return Etc/GMC-2 rather than just Etc/GMC although both are valid.

This implementation uses a tree to search for valid time-zone names in the parseText. The top level node of the tree has a length equal to the length of the shortest time-zone as well as the beginning characters of all other time-zones.

Specified by:

parse in interface DateTimeFormatterBuilder.DateTimePrinterParser

Parameters:

context - the context to use and parse into, not null

text - the input text to parse, not null

position - the position to start parsing at, from 0 to the text length

Returns:

the new parse position, where negative means an error with the error position encoded using the complement ~ operator

convertToZone

private ZoneId convertToZone(java.util.Set<java.lang.String> regionIds,
                             java.lang.String parsedZoneId,
                             boolean caseSensitive)

parsePrefixedOffset

private int parsePrefixedOffset(DateTimeParseContext context,
                                java.lang.CharSequence text,
                                int prefixPos,
                                int position)

prepareParser

private static DateTimeFormatterBuilder.ZoneIdPrinterParser.SubstringTree prepareParser(java.util.Set<java.lang.String> availableIDs)

Builds an optimized parsing tree.

Parameters:

availableIDs - the available IDs, not null, not empty

Returns:

the tree, not null

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
