    the absolute time at which the lock expires
  - getProcessInstanceId
```
String getProcessInstanceId()
```
    Returns:
    the id of the process instance the task exists in
  - getExecutionId
```
String getExecutionId()
```
    Returns:
    the id of the execution that the task is assigned to

  - getProcessDefinitionKey
```
String getProcessDefinitionKey()
```
    Returns:
    the key of the process definition the task's activity belongs to
  - getRetries
```
Integer getRetries()
```
    Returns:
    the number of retries left. The number of retries is provided by a task client, therefore the initial value is null.
