  - CronTrigger
```
public CronTrigger(String expression)
```
    Build a CronTrigger from the pattern provided in the default time zone.
    Parameters:
    expression - a space-separated list of time fields, following cron expression conventions
  - CronTrigger
```
public CronTrigger(String expression,
                   TimeZone timeZone)
```
    Build a CronTrigger from the pattern provided in the given time zone.
    Parameters:
    expression - a space-separated list of time fields, following cron expression conventions
    timeZone - a time zone in which the trigger times will be generated
- Method Detail
  - getExpression
```
public String getExpression()
```
    Return the cron pattern that this trigger has been built with.
  - nextExecutionTime
```
public Date nextExecutionTime(TriggerContext triggerContext)
```
    Determine the next execution time according to the given trigger context.
    Next execution times are calculated based on the completion time of the previous execution; therefore, overlapping executions won't occur.
    Specified by:
    nextExecutionTime in interface Trigger
    Parameters:
    triggerContext - context object encapsulating last execution times and last completion time
    Returns:
    the next execution time as defined by the trigger, or null if the trigger won't fire anymore
  - equals
```
public boolean equals(@Nullable
                      Object other)
```
    Overrides:
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    hashCode in class Object
  - toString
```
public String toString()
```
    Overrides:
    toString in class Object
