Method Detail

addContent

byte[] addContent(InputStream stream)
           throws IOException

Add the given content to the repository along with a reference tracked by name.

Parameters:

stream - stream from which the content can be read. Cannot be null

Returns:

the hash of the content that will be used as an internal identifier for the content. Will not be null

Throws:

IOException - if there is a problem reading the stream

addContentReference

void addContentReference(byte[] hash,
                         Object reference)

Adds a reference to the content hash.

Parameters:

hash - the hash of the deployment

reference - An identifier which must honour the equals() and hashCode() contracts. In the case of a deployment, this will be the deployment name. This is also used in #removeContent(byte[], String)

getContent

org.jboss.vfs.VirtualFile getContent(byte[] hash)

Get the content as a virtual file.

Parameters:

hash - the hash. Cannot be null

Returns:

the content as a virtual file

hasContent

boolean hasContent(byte[] hash)

Gets whether content with the given hash is stored in the repository.

Parameters:

hash - the hash. Cannot be null

Returns:

true if the repository has content with the given hash

syncContent

boolean syncContent(byte[] hash)

Synchronize content with the given hash. This may be used in favor of hasContent(byte[]) to explicitly allow additional operations to synchronize the content.

Parameters:

hash - the hash. Cannot be null

Returns:

true if the repository has content with the given hash

removeContent

void removeContent(byte[] hash,
                   Object reference)

Remove the given content from the repository. Remove the given content from the repository. The reference for name will be removed, and if there are no references left the deployment will be totally removed

Parameters:

hash - the hash. Cannot be null

reference - An identifier which must honour the equals() and hashCode() contracts. In the case of a deployment, this will be the deployment name. This is also used in addContentReference(byte[], Object)
