Interface FlowFileRecord

All Superinterfaces:

Comparable<FlowFile>, FlowFile

public interface FlowFileRecord
extends FlowFile

FlowFileRecord is a sub-interface of FlowFile and is used to provide additional information about FlowFiles that provide valuable information to the framework but should be hidden from components

Method Details

getPenaltyExpirationMillis

long getPenaltyExpirationMillis()

Returns:

the time (in millis since epoch) at which this FlowFile should no longer be penalized

getContentClaim

ContentClaim getContentClaim()

Returns:

the ContentClaim that holds the FlowFile's content

getContentClaimOffset

long getContentClaimOffset()

Returns:

the byte offset into the ContentClaim at which the FlowFile's content occurs. This mechanism allows multiple FlowFiles to have the same ContentClaim, which can be significantly more efficient for some implementations of ContentRepository
