- Method Detail
  - getEventId
```
long getEventId()
```
    Returns:
    a unique ID for this Provenance Event. Depending on the implementation, the Event ID may be set to -1 until the event has been added to the ProvenanceEventRepository
  - getEventTime
```
long getEventTime()
```
    Returns:
    the time at which this Provenance Event was created, as the number of milliseconds since epoch
  - getFlowFileEntryDate
```
long getFlowFileEntryDate()
```
    Returns:
    the EntryDate of the FlowFile to which this Event is associated
  - getLineageStartDate
```
long getLineageStartDate()
```
    Returns:
    the time at which the lineage began
  - getLineageIdentifiers
```
Set<String> getLineageIdentifiers()
```
    Returns:
    the set of all lineage identifiers that are associated with the FlowFile for which this Event was created
  - getFileSize
```
long getFileSize()
```
    Returns:
    the size of the FlowFile to which this Event is associated
  - getPreviousFileSize
```
Long getPreviousFileSize()
```
    Returns:
    the previous size of the FlowFile to which this Event is associated, if the FlowFile previously had content and its size was known; otherwise, returns null
  - getEventDuration
```
long getEventDuration()
```
    Returns:
    the amount of time in milliseconds that elapsed while performing this event. If not populated, the value -1 will be returned
  - getEventType
```
ProvenanceEventType getEventType()
```
    Returns:
    the type of this Provenance Event
  - getAttributes
```
Map<String,String> getAttributes()
```
    Returns:
    all FlowFile attributes that were associated with the FlowFile at the time that this ProvenanceEvent was created
  - getPreviousAttributes
```
Map<String,String> getPreviousAttributes()
```
    Returns:
    all FlowFile attributes that existed on the FlowFile before this event occurred
  - getUpdatedAttributes
```
Map<String,String> getUpdatedAttributes()
```
    Returns:
    all FlowFile attributes that were updated as a result of this event
  - getComponentId
```
String getComponentId()
```
    Returns:
    the ID of the Processor/component that created this Provenance Event
  - getComponentType
```
String getComponentType()
```
    Returns:
    the fully-qualified Class Name of the Processor/component that created this Provenance Event
  - getTransitUri
```
String getTransitUri()
```
    Returns:
    a URI that provides information about the System and Protocol information over which the transfer occurred. The intent of this field is such that both the sender and the receiver can publish the events to an external Enterprise-wide system that is then able to correlate the SEND and RECEIVE events.
  - getSourceSystemFlowFileIdentifier
```
String getSourceSystemFlowFileIdentifier()
```
    Since the receiving system will usually refer to the data using a different identifier than the source system, this information is used to correlate the receive system's FlowFile with the sending system's data
    
    Returns:
    the UUID that the Source System used to refer to this data; this is applicable only when the ProvenanceEventType is of type RECEIVE
  - getFlowFileUuid
```
String getFlowFileUuid()
```
    Returns:
    the UUID of the FlowFile with which this Event is associated
  - getParentUuids
```
List<String> getParentUuids()
```
    Returns:
    the UUID's of all Parent FlowFiles. This is applicable only when the ProvenanceEventType is of type SPAWN
  - getChildUuids
```
List<String> getChildUuids()
```
    Returns:
    the UUID's of all Child FlowFiles. This is applicable only when the ProvenanceEventType is of type SPAWN
  - getAlternateIdentifierUri
```
String getAlternateIdentifierUri()
```
    Returns:
    the Alternate Identifier associated with the FlowFile with which this Event is associated. This is applicable only when the ProvenanceEventType is of type ProvenanceEventType.ADDINFO
  - getDetails
```
String getDetails()
```
    Returns:
    the details for this record, if any were supplied. Otherwise, returns null
  - getRelationship
```
String getRelationship()
```
    Returns:
    the relationship to which this record was routed if the event type is ProvenanceEventType.ROUTE. The relationship is applicable only to this type
  - getSourceQueueIdentifier
```
String getSourceQueueIdentifier()
```
    Returns:
    the identifier of the queue from which the FlowFile was taken, if any. If the FlowFile is created as a result of this event (in this case, the Event Type is one of null null null null null null null null ProvenanceEventType.CREATE, ProvenanceEventType.RECEIVE, ProvenanceEventType.FORK, ProvenanceEventType.JOIN, or ProvenanceEventType.CLONE), or if the queue identifier is unknown, then this method will return null
  - getContentClaimSection
```
String getContentClaimSection()
```
    Returns:
    the Section for the Content Claim that this Event refers to, if any; otherwise, returns null
  - getPreviousContentClaimSection
```
String getPreviousContentClaimSection()
```
    Returns:
    the Section for the Content Claim that the FlowFile previously referenced, if any; otherwise, returns null
  - getContentClaimContainer
```
String getContentClaimContainer()
```
    Returns:
    the Container for the Content Claim that this Event refers to, if any; otherwise, returns null
  - getPreviousContentClaimContainer
```
String getPreviousContentClaimContainer()
```
    Returns:
    the Container for the Content Claim that the FlowFile previously referenced, if any; otherwise, returns null
  - getContentClaimIdentifier
```
String getContentClaimIdentifier()
```
    Returns:
    the Identifier for the Content Claim that this Event refers to, if any; otherwise, returns null
  - getPreviousContentClaimIdentifier
```
String getPreviousContentClaimIdentifier()
```
    Returns:
    the Identifier for the Content Claim that the FlowFile previously referenced, if any; otherwise, returns null
  - getContentClaimOffset
```
Long getContentClaimOffset()
```
    Returns:
    the offset into the Content Claim at which the FlowFile's content begins, if any; otherwise, returns null
  - getPreviousContentClaimOffset
```
Long getPreviousContentClaimOffset()
```
    Returns:
    the offset into the Content Claim at which the FlowFile's previous content began, if any; otherwise, returns null
