- the test style to output, not null

Method Details

print
public void print(Calendrical calendrical, Appendable appendable, DateTimeFormatSymbols symbols) throws IOException Prints the calendrical object to the appendable.- Specified by:
print
in interfaceDateTimePrinter
- Parameters:
calendrical
- the calendrical to print, not nullappendable
- the appendable to add to, not nullsymbols
- the formatting symbols to use, not null- Throws:
IOException
- if the append throws an exception
-
isPrintDataAvailable
Checks if the calendrical contains the data necessary to be printed.The implementation should not check the validity of the data, just whether there is sufficient data to attempt a print.
- Specified by:
isPrintDataAvailable
in interfaceDateTimePrinter
- Parameters:
calendrical
- the calendrical to check, not null- Returns:
- true if the calendrical can be printed, false if not
-
parse
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 interfaceDateTimeParser
- Parameters:
context
- the context to use and parse into, not nullparseText
- the input text to parse, not nullposition
- 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
-
prepareParser
Builds an optimized parsing tree.- Parameters:
availableIDs
- the available IDs, not null, not empty- Returns:
- the tree, never null
-
