Method Detail

target

public String target()

The URI of the original target resource this record holds information about as an unparsed string.

Strips enclosing angle brackets if present as a compatibility quirk with WARC 1.0.

targetURI

public URI targetURI()

The URI of the original target resource this record holds information about.

payloadDigest

public Optional<WarcDigest> payloadDigest()

Digest values that were calculated by applying hash functions to payload.

identifiedPayloadType

public Optional<MediaType> identifiedPayloadType()

A content-type that was identified by an independent check (not just what the server said).

payload

public Optional<WarcPayload> payload()
                              throws IOException

Returns the payload of this record if one is present.

This method returns an empty optional when the payload is undefined for this record type or if this library does not know how to parse the body in order to extract the payload. If the payload is well defined but happens to be zero bytes in length this method still returns a WarcPayload object.

Throws:

IOException

warcinfoID

public Optional<URI> warcinfoID()

The ID of a Warcinfo record associated with this record.

toString

public String toString()

Overrides:
