                                      throws IOException

Throws:

IOException

Method Detail

write

public Hash write(InputStream inputStream)
           throws IOException

Description copied from interface: ContentAddressableStore

Write content to the store, returning its hash. If the store already contains this content, the write is discarded but the hash is returned as normal.

Parameters:

inputStream - Content to be written

Returns:

hash of content

Throws:

IOException

write

public Hash write(InputStream inputStream,
                  List<ContentEncoding> encodings)
           throws IOException

Description copied from interface: ContentAddressableStore

Write content to the store in raw format and also formats specified in the ContentEncodings. If encodings is null or an empty list then no encodings are used.

Parameters:

inputStream - Content to be written

Returns:

hash of (raw) content

Throws:

IOException

contains

public boolean contains(Hash hash)

Description copied from interface: ContentAddressableStore

Check whether content exists in the store with the specified hash

Parameters:

hash - Hash of content to check

Returns:

true if content exists in the store with specified hash

contains

public boolean contains(Hash hash,
                        ContentEncoding contentEncoding)

Description copied from interface: ContentAddressableStore

Check whether content exists in the store with the specified hash with the specified encoding

Parameters:

hash - Hash of content to check

contentEncoding - Type of encoding to use.

Returns:

true if content exists in the store with specified hash and specified encoding.

read

public InputStream read(Hash hash)
                 throws FileNotFoundException

Description copied from interface: ContentAddressableStore

Read content from the store.

Parameters:

hash - The hash of the content to read.

Returns:

InputStream of content if content exists; otherwise null.

Throws:

FileNotFoundException

read

public InputStream read(Hash hash,
                        ContentEncoding contentEncoding)
                 throws FileNotFoundException

Description copied from interface: ContentAddressableStore

Read content from the store, returning using the given encoding.

Parameters:

hash - The hash of the (raw) content to read.

contentEncoding - Type of encoding to use to return the stream. If null then no encoding is used.

Returns:

InputStream of content if content exists; otherwise null.

Throws:

FileNotFoundException

getContentLength

public long getContentLength(Hash hash)
                      throws IOException

Description copied from interface: ContentAddressableStore

Get the length of the content with the specified hash

Parameters:

hash - The hash of the content

Returns:

The length of the content, or -1 if no content with the specified hash exists.

Throws:

IOException

getContentLength

public long getContentLength(Hash hash,
                             ContentEncoding contentEncoding)
                      throws IOException

Description copied from interface: ContentAddressableStore

Get the length of the encoded content with the specified hash.

Parameters:

hash - The hash of the content

contentEncoding - The encoding type to use. If null then no encoding is used and the raw content is assumed.

Returns:

The length of the content, or -1 if no content with the specified hash exists.

Throws:

IOException

getHashes

public List<Hash> getHashes()
                     throws IOException

Description copied from interface: ContentAddressableStore

Get a list of all hashes in the store. The list is generated lazily by querying the filesystem, and thus will not behave deterministically if more content is added while this function is called.

Returns:

List of hashes in the store.

Throws:

IOException

delete

public boolean delete(Hash hash)
               throws IOException

Description copied from interface: ContentAddressableStore

Delete content from the store.

Parameters:

hash - Hash of content to delete

Returns:

true if the content existed and was deleted; otherwise false.

Throws:

IOException

close

public void close()
