Method Details

setCacheExpirationTime

public void setCacheExpirationTime(long cacheExpirationTime)

Sets cache expiration time after which the document shall be refreshed Default : -1 (the cache does not expire)

Parameters:

cacheExpirationTime - indicates time after which the document shall be refreshed in milliseconds

test

public boolean test(DocumentWithSha2 documentWithSha2)

This method evaluates whether the sha2 digest match the original document

Parameters:

documentWithSha2 - DocumentWithSha2 containing the original document and downloaded sha2 document

Returns:

TRUE if the sha2 corresponding to the document match the digest of the cached content and no refresh is required, FALSE otherwise (if refresh is required for any reason)

getCurrentTime

protected Date getCurrentTime()

This method returns the current time to compare NextUpdate against

Returns:

Date

isCacheExpired

protected boolean isCacheExpired(DSSDocument document)

This method verifies whether the cache of the document has expired. Note : this method supports only default eu.europa.esig.dss.model.FileDocument implementation. Override this method, should you need any processing of other implementations.

Parameters:

document - DSSDocument to verify

Returns:

TRUE if the cache of the document has expired, FALSE otherwise
