- Method Detail
  - getId
```
String getId()
```
    Returns:
    
    the id of the task
  - getTopicName
```
String getTopicName()
```
    Returns:
    
    the name of the topic the task belongs to
  - getWorkerId
```
String getWorkerId()
```
    Returns:
    
    the id of the worker that has locked the task
  - getLockExpirationTime
```
Date getLockExpirationTime()
```
    Returns:
    
    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
  - getActivityId
```
String getActivityId()
```
    Returns:
    
    the id of the activity for which the task is created
  - getActivityInstanceId
```
String getActivityInstanceId()
```
    Returns:
    
    the id of the activity instance in which context the task exists
  - getProcessDefinitionId
```
String getProcessDefinitionId()
```
    Returns:
    
    the id of the process definition the tasks activity belongs to
  - getProcessDefinitionKey
```
String getProcessDefinitionKey()
```
    Returns:
    
    the key of the process definition the tasks activity belongs to
  - getProcessDefinitionVersionTag
```
String getProcessDefinitionVersionTag()
```
    Returns:
    
    the version tag of the process definition the tasks 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.
  - getErrorMessage
```
String getErrorMessage()
```
    Returns:
    
    the full error message submitted with the latest reported failure executing this task; null if no failure was reported previously or if no error message was submitted
    
    See Also:
    
    ExternalTaskService.handleFailure(String, String, String, int, long)
  - getErrorDetails
```
String getErrorDetails()
```
    Returns:
    
    error details submitted with the latest reported failure executing this task; null if no failure was reported previously or if no error details was submitted
    
    See Also:
    
    ExternalTaskService.handleFailure(String, String, String, String, int, long)
  - getVariables
```
VariableMap getVariables()
```
    Returns:
    
    a map of variables that contains an entry for every variable that was specified at fetching time, if such a variable exists in the tasks ancestor execution hierarchy.
  - getTenantId
```
String getTenantId()
```
    Returns:
    
    the id of the tenant the task belongs to. Can be null if the task belongs to no single tenant.
  - getPriority
```
long getPriority()
```
    Returns the priority of the locked external task. The default priority is 0.
    
    Returns:
    
    the priority of the external task
  - getBusinessKey
```
String getBusinessKey()
```
    Returns the business key of the process instance the external task belongs to
    
    Returns:
    
    the business key
  - getExtensionProperties
```
Map<String,String> getExtensionProperties()
```
    Returns a map of custom extension properties if the fetch instructions indicate to include extension properties. If extension properties are included, the returned map contains any extension property that is defined in the model definition of the external task. If extension properties not included or no properties are defined for the external task, the map will be empty.
    
    Returns:
    
    a map with all defined custom extension properties, never null
