Method Summary

Modifier and Type	Method	Description
protected boolean	checkDigestToCompute(ReplicatorOrder businessIn)	Default based on QuarkusProperties.serverComputeSha256
protected boolean	checkPullAble(ReplicatorOrder replicatorOrder, io.vertx.core.MultiMap headers)	The implementation must check using business object that get inputStream request (server sending InputStream as result) is valid according to the businessIn from te Rest API and the headers.
protected void	checkPushAble(ReplicatorOrder payload, MultipleActionsInputStream inputStream)	Check if the request for POST is valid, and if so, adapt the given MultipleActionsInputStream that will be used to consume the original InputStream.
protected AccessorObject	getAnswerPushInputStream(ReplicatorOrder replicatorOrder, String finalHash, long size)	Returns a BusinessOut in case of POST (receiving InputStream on server side).
protected Map<String,String>	getHeaderError(ReplicatorOrder replicatorOrder, int status)	Return headers for error message.
protected Map<String,String>	getHeaderPullInputStream(ReplicatorOrder replicatorOrder)	Returns a Map for Headers response in case of GET, added to InputStream get above (server is sending the InputStream back to the client) (example: headers for object name, object size...)
protected Map<String,String>	getHeaderPushInputStream(ReplicatorOrder replicatorOrder, String finalHash, long size, AccessorObject accessorObject)	Returns a Map for Headers response in case of POST (receiving InputStream on server side).
protected InputStream	getPullInputStream(ReplicatorOrder replicatorOrder)	Returns the InputStream required for GET (server is sending the InputStream back to the client).
protected void	postSetup()	Method to override for post setup

public RemoteReplicatorStreamHandler()

Method Details

postSetup

protected void postSetup()

Description copied from class: StreamHandlerAbstract

Method to override for post setup

Overrides:

postSetup in class StreamHandlerAbstract<ReplicatorOrder,AccessorObject>

checkDigestToCompute

protected boolean checkDigestToCompute(ReplicatorOrder businessIn)

Description copied from class: StreamHandlerAbstract

Default based on QuarkusProperties.serverComputeSha256

Overrides:

checkDigestToCompute in class StreamHandlerAbstract<ReplicatorOrder,AccessorObject>

Returns:

True if the digest is to be computed on the fly

getAnswerPushInputStream

protected AccessorObject getAnswerPushInputStream(ReplicatorOrder replicatorOrder,
 String finalHash,
 long size)

Description copied from class: StreamHandlerAbstract

Returns a BusinessOut in case of POST (receiving InputStream on server side). The implementation shall use the business logic to get the right BusinessOut object to return. (example: getting the StorageObject object, including the computed or given Hash)

Specified by:

getAnswerPushInputStream in class StreamHandlerAbstract<ReplicatorOrder,AccessorObject>

Parameters:

replicatorOrder - businessIn as passed in constructor

finalHash - the final Hash if computed on the fly, or the original given one

size - the real size read (from received stream, could be compressed size if decompression is off at construction)

getHeaderPushInputStream

protected Map<String,String> getHeaderPushInputStream(ReplicatorOrder replicatorOrder,
 String finalHash,
 long size,
 AccessorObject accessorObject)

Description copied from class: StreamHandlerAbstract

Returns a Map for Headers response in case of POST (receiving InputStream on server side). (example: headers for object name, object size, ...)

Specified by:

getHeaderPushInputStream in class StreamHandlerAbstract<ReplicatorOrder,AccessorObject>

Parameters:

replicatorOrder - businessIn as passed in constructor

finalHash - the final Hash if computed on the fly, or the original given one

size - the real size read

accessorObject - previously constructed from getAnswerPushInputStream

checkPushAble

protected void checkPushAble(ReplicatorOrder payload,
 MultipleActionsInputStream inputStream)

Description copied from class: StreamHandlerAbstract

Check if the request for POST is valid, and if so, adapt the given MultipleActionsInputStream that will be used to consume the original InputStream. The implementation shall use the business logic to check the validity for this InputStream reception (from client to server) and, if valid, use the MultipleActionsInputStream, either as is or as a standard InputStream. (example: check through Object Storage that object does not exist yet, and if so add the consumption of the stream for the Object Storage object creation). Note that the stream might be kept compressed if keepInputStreamCompressed was specified at construction.

Specified by:

checkPushAble in class StreamHandlerAbstract<ReplicatorOrder,AccessorObject>

checkPullAble

protected boolean checkPullAble(ReplicatorOrder replicatorOrder,
 io.vertx.core.MultiMap headers)

Description copied from class: StreamHandlerAbstract

The implementation must check using business object that get inputStream request (server sending InputStream as result) is valid according to the businessIn from te Rest API and the headers. (example: ObjectStorage check of existence of object)

Specified by:

checkPullAble in class StreamHandlerAbstract<ReplicatorOrder,AccessorObject>

Returns:

True if the read action is valid for this businessIn object and headers

getPullInputStream

protected InputStream getPullInputStream(ReplicatorOrder replicatorOrder)

Description copied from class: StreamHandlerAbstract

Returns the InputStream required for GET (server is sending the InputStream back to the client). The implementation shall use the business logic and controls to get the InputStream to return. (example: getting the Object Storage object stream)

Specified by:

getPullInputStream in class StreamHandlerAbstract<ReplicatorOrder,AccessorObject>

Parameters:

replicatorOrder - businessIn as passed in constructor

getHeaderPullInputStream

protected Map<String,String> getHeaderPullInputStream(ReplicatorOrder replicatorOrder)

Description copied from class: StreamHandlerAbstract

Returns a Map for Headers response in case of GET, added to InputStream get above (server is sending the InputStream back to the client) (example: headers for object name, object size...)

Specified by:

getHeaderPullInputStream in class StreamHandlerAbstract<ReplicatorOrder,AccessorObject>

Parameters:

replicatorOrder - businessIn as passed in constructor

getHeaderError

protected Map<String,String> getHeaderError(ReplicatorOrder replicatorOrder,
 int status)

Description copied from class: StreamHandlerAbstract

Return headers for error message. (example: get headers in case of error as Object name, Bucket name...)

Specified by:

getHeaderError in class StreamHandlerAbstract<ReplicatorOrder,AccessorObject>
