Methods' Details |
openEncryptedStream
- Description
- allows to get access to a child encrypted stream with EncryptionData.
If storage does not allow any encryption this method will always throw
::com::sun::star::packages::NoEncryptionException.
In case the stream is open in readonly mode the
XStream::getOutputStream
method will return an empty reference.
- Parameter sStreamName
- the name of the substream that should be open
- Parameter nOpenMode
- a mode the stream should be open in,
can be a combination of ElementModes values
- Parameter aEncryptionData
- this parameter allowes to specify an encryption data to decrypt the
stream, the encryption data must be correct, otherwise an
exception will be thrown
- Throws
- ::com::sun::star::embed::InvalidStorageException
this storage is in invalid state for any reason
- Throws
- ::com::sun::star::lang::IllegalArgumentException
one of provided arguments is illegal
- Throws
- ::com::sun::star::packages::NoEncryptionException
the stream is not encrypted
- Throws
- ::com::sun::star::packages::WrongPasswordException
the provided encryption data is wrong
- Throws
- ::com::sun::star::io::IOException
in case of io errors during stream opening
- Throws
- ::com::sun::star::embed::StorageWrappedTargetException
wraps other exceptions

cloneEncryptedStream
- Description
- allows to get readonly copy of a child encrypted stream with encryption
data.
If storage does not allow any encryption this method will always throw
::com::sun::star::packages::NoEncryptionException.
The stream is open in readonly mode so the
XStream::getOutputStream
method will return an empty reference.
This method allows to specify encryption data for the child stream
explicitly.
- Parameter sStreamName
- the name of the substream that should be copied
- Parameter aEncryptionData
- this parameter allowes to specify an encryption data for the
stream, the encryption data must be correct, otherwise an
exception will be thrown
- Throws
- ::com::sun::star::embed::InvalidStorageException
this storage is in invalid state for any reason
- Throws
- ::com::sun::star::lang::IllegalArgumentException
one of provided arguments is illegal
- Throws
- ::com::sun::star::packages::NoEncryptionException
the stream is not encrypted
- Throws
- ::com::sun::star::packages::WrongPasswordException
the provided encryption data is wrong
- Throws
- ::com::sun::star::io::IOException
in case of io errors during stream opening
- Throws
- ::com::sun::star::embed::StorageWrappedTargetException
wraps other exceptions
