Method Detail

store

void store(java.lang.String id,
         java.io.InputStream stream)
           throws BinaryStorageException

Save the attachment stream in the binary storage location.

Parameters:

id - String - calculated key (attachment id) from blackboard service based on record Id and file name. The key will serve to identify (persistence scope) current folder & file inside of binary storage.

stream - InputStream - attachment stream

Throws:

BinaryStorageException - in case of any exception

store

void store(java.lang.String id,
         byte[] blob)
           throws BinaryStorageException

Save the attachment byte array content in the binary storage location.

Parameters:

id - String - calculated key (attachment id) from blackboard service based on record Id and file name. The key will serve to identify (persistence scope) current folder & file inside of binary storage.

blob - byte[] - file content to be stored in binary storage

Throws:

BinaryStorageException - in case of any exception

fetchAsByte

byte[] fetchAsByte(java.lang.String id)
                   throws BinaryStorageException

Fetch an already persisted attachment through (BinaryStorageService.storeRecordAttachment) from binary storage as byte array.

Parameters:

id - String - calculated key (attachment id) from blackboard service based on record Id and file name. The key value passed by the Blackboard service shall be identically with the same one, passed one step previously (through the createStorageFile service) in order to get exactly the same file content.

Returns:

byte[] - file content

Throws:

BinaryStorageException - in case of any exception

fetchAsStream

java.io.InputStream fetchAsStream(java.lang.String id)
                                  throws BinaryStorageException

Fetch an already persisted attachment through (BinaryStorageService.storeRecordAttachment) from binary storage as InputStream.

Parameters:

id - String - calculated key (attachment id) from blackboard service based on record Id and file name. The key value passed by the Blackboard service shall be identically with the same one, passed one step previously (through the createStorageFile service) in order to get exactly the same file content.

Returns:

InputStream - file content

Throws:

BinaryStorageException - in case of any exception

remove

void remove(java.lang.String id)
            throws BinaryStorageException

Removes folder&file structure from the binary storage, based on the passed key.

Parameters:

id - String - calculated key (attachment id) from blackboard service based on record Id and file name.

Throws:

BinaryStorageException - in case of any exception

fetchSize

long fetchSize(java.lang.String id)
               throws BinaryStorageException

Fetch size of persisted attachment.

Parameters:

id -

Returns:

int - attachment size

Throws:

BinaryStorageException - in case of any exception
