Member Function Documentation

getPlainRawStreamElement()

::com::sun::star::io::XInputStream getPlainRawStreamElement	(	[in] string	sStreamName	)
raises	(	::com::sun::star::embed::InvalidStorageException,
		::com::sun::star::lang::IllegalArgumentException,
		::com::sun::star::container::NoSuchElementException,
		::com::sun::star::io::IOException,
		::com::sun::star::embed::StorageWrappedTargetException
	)

allows to get a plain raw stream representing a package stream.

This method returns a stream from the package as it is stored there, without any decompression/description and etc. This method can be helpful to check file consistency, for example by signing.

Returns

the raw representation of encrypted stream with all the data required to copy the stream without information loss

Parameters

sStreamName

the name of the substream that should be open

Exceptions

com::sun::star::embed::InvalidStorageException	this storage is in invalid state for any reason
com::sun::star::lang::IllegalArgumentException	one of provided arguments is illegal
com::sun::star::container::NoSuchElementException	there is no element with specified name
com::sun::star::io::IOException	in case of io errors during stream opening
com::sun::star::embed::StorageWrappedTargetException	wraps other exceptions

getRawEncrStreamElement()

::com::sun::star::io::XInputStream getRawEncrStreamElement	(	[in] string	sStreamName	)
raises	(	::com::sun::star::embed::InvalidStorageException,
		::com::sun::star::lang::IllegalArgumentException,
		::com::sun::star::packages::NoEncryptionException,
		::com::sun::star::container::NoSuchElementException,
		::com::sun::star::io::IOException,
		::com::sun::star::embed::StorageWrappedTargetException
	)

allows to get a raw stream representing encrypted stream with header.

This method allows to transport encrypted streams without decryption. Mainly this method is introduced to allow to copy one encrypted storage stream to another without decryption. It is not recommended to use this method outside of storage implementation since different storages implementation could have different encryption format. If the method is used outside of storage implementation the user code is responsible to get sure that the raw format of source and target storages is the same.

The difference of this method from the previous one is that it handles only encrypted streams. The contents of returned by these methods streams can differ for the same entry, since this method can add additional data into the stream to allow successful insertion.

Parameters

sStreamName

the name of the substream that should be open

Exceptions

com::sun::star::embed::InvalidStorageException	this storage is in invalid state for any reason
com::sun::star::lang::IllegalArgumentException	one of provided arguments is illegal
com::sun::star::packages::NoEncryptionException	the stream is not an encrypted one
com::sun::star::container::NoSuchElementException	there is no element with specified name
com::sun::star::io::IOException	in case of io errors during stream opening
com::sun::star::embed::StorageWrappedTargetException	wraps other exceptions

insertRawEncrStreamElement()

void insertRawEncrStreamElement	(	[in] string	sStreamName,
		[in] ::com::sun::star::io::XInputStream	xInStream
	)
raises	(	::com::sun::star::embed::InvalidStorageException,
		::com::sun::star::lang::IllegalArgumentException,
		::com::sun::star::packages::NoRawFormatException,
		::com::sun::star::container::ElementExistException,
		::com::sun::star::io::IOException,
		::com::sun::star::embed::StorageWrappedTargetException
	)

allows to insert a raw stream representing encrypted stream with header.

This method allows to insert a stream retrieved by XStorageRawAccess::getRawEncrStreamElement() into a storage.

This method allows to transport encrypted streams without decryption. Mainly this method is introduced to allow to copy one encrypted storage stream to another without decryption. It is not recommended to use this method outside of storage implementation since different storages implementation could have different encryption format.

Parameters

sStreamName	the name of the substream that should be open
xInStream	a raw stream representing encrypted stream

Exceptions

com::sun::star::embed::InvalidStorageException	this storage is in invalid state for any reason
com::sun::star::lang::IllegalArgumentException	one of provided arguments is illegal
com::sun::star::packages::NoRawFormatException	the stream is not one of raw package stream format
com::sun::star::container::ElementExistException	an element with specified name already exists
com::sun::star::io::IOException	in case of io errors during stream opening
com::sun::star::embed::StorageWrappedTargetException	wraps other exceptions
