Method Detail

createInputStream

public CompressionInputStream createInputStream(InputStream in)
                                         throws IOException

Description copied from interface: ICompressionProvider

Creates an input stream that decompresses data (according to the provider's implementation)

Specified by:

createInputStream in interface ICompressionProvider

Parameters:

in - An existing input stream to wrap

Returns:

a CompressionInputStream object that decompresses incoming data

Throws:

IOException

supportsInput

public boolean supportsInput()

Description copied from interface: ICompressionProvider

Whether this compression provider supports input streams

Specified by:

supportsInput in interface ICompressionProvider

Returns:

true if the provider supports input streams, false otherwise

createOutputStream

public CompressionOutputStream createOutputStream(OutputStream out)
                                           throws IOException

Description copied from interface: ICompressionProvider

Creates an output stream that compresses data (according to the provider's implementation)

Specified by:

createOutputStream in interface ICompressionProvider

Parameters:

out - An existing output stream to wrap

Returns:

a CompressionOutputStream object that compresses outgoing data

Throws:

IOException

supportsOutput

public boolean supportsOutput()

Description copied from interface: ICompressionProvider

Whether this compression provider supports output streams

Specified by:

supportsOutput in interface ICompressionProvider

Returns:

true if the provider supports output streams, false otherwise

getDescription

public String getDescription()

Gets the description for the compression provider.

Specified by:

getDescription in interface ICompressionProvider

Returns:

a description of the provider. For core plugins this needs to match what's in the XML file

getName

public String getName()

Gets the name for the compression provider.

Specified by:

getName in interface ICompressionProvider

Returns:

the name of the provider. For core plugins this needs to match what's in the XML file

getDefaultExtension

public String getDefaultExtension()

Description copied from interface: ICompressionProvider

Gets the default file extension for this provider. If the streams are wrapped in File streams, this method can be used to determine an appropriate extension to append to the filename so the file will be recognized as an artifact of the compression mechanism (.zip, .bz2, e.g.)

Specified by:

getDefaultExtension in interface ICompressionProvider

Returns:

A String containing the default file extension for this provider
