start

public void start()

Description copied from class: AbstractBinaryStore

Initialize the store and get ready for use.

Overrides:

start in class AbstractBinaryStore

shutdown

public void shutdown()

Overrides:

shutdown in class AbstractBinaryStore

getCaches

public List<org.infinispan.Cache<?,?>> getCaches()

storeValue

public BinaryValue storeValue(InputStream inputStream)
                       throws BinaryStoreException,
                              SystemFailureException

Description copied from interface: BinaryStore

Store the binary value and return the JCR representation. Note that if the binary content in the supplied stream is already persisted in the store, the store may simply return the binary value referencing the existing content.

Parameters:

inputStream - the stream containing the binary content to be stored; may not be null

Returns:

the binary value representing the stored binary value; never null

Throws:

BinaryStoreException - if there any unexpected problem

SystemFailureException

getInputStream

public InputStream getInputStream(BinaryKey binaryKey)
                           throws BinaryStoreException

Description copied from interface: BinaryStore

Get an InputStream to the binary content with the supplied key.

Parameters:

binaryKey - the key to the binary content; never null

Returns:

the input stream through which the content can be read, never null

Throws:

BinaryStoreException - if there is a problem reading the content from the store or if a valid, non-null InputStream cannot be returned for the given key.

markAsUnused

public void markAsUnused(Iterable<BinaryKey> keys)
                  throws BinaryStoreException

Description copied from interface: BinaryStore

Mark the supplied binary keys as unused, but key them in quarantine until needed again (at which point they're removed from quarantine) or until BinaryStore.removeValuesUnusedLongerThan(long, TimeUnit) is called. This method ignores any keys for values not stored within this store.

Parameters:

keys - the keys for the binary values that are no longer needed

Throws:

BinaryStoreException - if there is a problem marking any of the supplied binary values as unused

removeValuesUnusedLongerThan

public void removeValuesUnusedLongerThan(long minimumAge,
                                         TimeUnit unit)
                                  throws BinaryStoreException

Description copied from interface: BinaryStore

Remove binary values that have been unused for at least the specified amount of time.

Parameters:

minimumAge - the minimum time that a binary value has been unused before it can be removed; must be non-negative

unit - the time unit for the minimum age; may not be null

Throws:

BinaryStoreException - if there is a problem removing the unused values

getStoredMimeType

protected String getStoredMimeType(BinaryValue binary)
                            throws BinaryStoreException

Description copied from class: AbstractBinaryStore

Returns the stored mime-type of a binary value.

Specified by:

getStoredMimeType in class AbstractBinaryStore

Parameters:

binary - a non-null BinaryValue

Returns:

either a non-empty String if a stored mimetype exists, or null if such a value doesn't exist yet.

Throws:

BinaryStoreException - if there's a problem accessing the binary store or if the binary value cannot be found in the store

storeMimeType

protected void storeMimeType(BinaryValue binary,
                             String mimeType)
                      throws BinaryStoreException

Description copied from class: AbstractBinaryStore

Stores the given mime-type for a binary value.

Specified by:

storeMimeType in class AbstractBinaryStore

Parameters:

binary - a non-null BinaryValue

mimeType - a non-empty String

Throws:

BinaryStoreException - if there's a problem accessing the binary store

getExtractedText

public String getExtractedText(BinaryValue binary)
                        throws BinaryStoreException

Description copied from class: AbstractBinaryStore

Returns the extracted text of a binary value, or null if such text hasn't been stored previously (but the binary value can be found in the store)

Specified by:

getExtractedText in class AbstractBinaryStore

Parameters:

binary - a non-null BinaryValue instance from which the text was extracted

Returns:

a String representing the extracted text, or null if such text hasn't been stored in this store previously.

Throws:

BinaryStoreException - if the binary value cannot be found in the store.

storeExtractedText

public void storeExtractedText(BinaryValue binary,
                               String extractedText)
                        throws BinaryStoreException

Description copied from class: AbstractBinaryStore

Stores the extracted text of a binary value into this store.

Specified by:

storeExtractedText in class AbstractBinaryStore

Parameters:

binary - a non-null BinaryValue instance from which the text was extracted

extractedText - a non-null and non-blank string representing the extracted text

Throws:

BinaryStoreException - if the operation fails or if the extracted text cannot be stored for the given binary value (regardless of the reason)

getAllBinaryKeys

public Iterable<BinaryKey> getAllBinaryKeys()
                                     throws BinaryStoreException

Description copied from interface: BinaryStore

Obtain an iterable implementation containing all of the store's binary keys. The resulting iterator may be lazy, in the sense that it may determine additional BinaryKeys only as the iterator is used.

Returns:

the iterable set of binary keys; never null

Throws:

BinaryStoreException - if anything unexpected happens.
