Method Detail

parse

public FieldExpression parse(String expression)

Parse given expression for a single cron field.

Parameters:

expression - - String

Returns:

CronFieldExpression object that with interpretation of given String parameter

parseBetween

protected FieldExpression parseBetween(String[] array)

parseOn

protected On parseOn(String exp)

parseOnWithHash

protected On parseOnWithHash(String exp)

parseOnWithQuestionMark

protected On parseOnWithQuestionMark(String exp)

parseOnWithLW

protected On parseOnWithLW(String exp)

parseOnWithL

protected On parseOnWithL(String exp)

parseOnWithL

protected On parseOnWithL(String exp,
                          IntegerFieldValue daysBefore)

parseOnWithW

protected On parseOnWithW(String exp)

mapToIntegerFieldValue

protected IntegerFieldValue mapToIntegerFieldValue(String string)

map

protected FieldValue<?> map(String string)

stringToInt

protected int stringToInt(String exp)

Maps string expression to integer. If no mapping is found, will try to parse String as Integer

Parameters:

exp - - expression to be mapped

Returns:

integer value for string expression

intToInt

protected int intToInt(Integer exp)

Maps integer values to another integer equivalence. Always consider mapping higher integers to lower once. Ex.: if 0 and 7 mean the same, map 7 to 0.

Parameters:

exp - - integer to be mapped

Returns:

Mapping integer. If no mapping int is found, will return exp
