Constructor Detail

CronSequence

public CronSequence()

Mandatory for the Externalizable instances empty constructor.

CronSequence

public CronSequence(java.lang.String cronExpression)

Creates a CronSequence instance with given Cron expression. Examples:

0 0 9-18 ? * MON-FRI: defines the Rule should be fired at 9:00, 10:00... 18:00, every working day (Monday to Friday) 0 0 0-2 * * ?: defines the Rule should be fired at 00am, 01:00 am and 02:00 every morning. 0 0 10 01 * ?: defines the Rule should be fired at 10:00 am on the 1st day of each month .

Parameters:

cronExpression - Cron experssion

Method Detail
