方法详细资料

createInputStream

public CompressionInputStream createInputStream(InputStream in)
                                         throws IOException

从接口复制的说明: CompressionProvider

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

指定者:

createInputStream 在接口中 CompressionProvider

参数:

in - An existing input stream to wrap

返回:

a CompressionInputStream object that decompresses incoming data

抛出:

IOException

supportsInput

public boolean supportsInput()

从接口复制的说明: CompressionProvider

Whether this compression provider supports input streams

指定者:

supportsInput 在接口中 CompressionProvider

返回:

true if the provider supports input streams, false otherwise

createOutputStream

public CompressionOutputStream createOutputStream(OutputStream out)
                                           throws IOException

从接口复制的说明: CompressionProvider

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

指定者:

createOutputStream 在接口中 CompressionProvider

参数:

out - An existing output stream to wrap

返回:

a CompressionOutputStream object that compresses outgoing data

抛出:

IOException

supportsOutput

public boolean supportsOutput()

从接口复制的说明: CompressionProvider

Whether this compression provider supports output streams

指定者:

supportsOutput 在接口中 CompressionProvider

返回:

true if the provider supports output streams, false otherwise

getDescription

public String getDescription()

Gets the description for the compression provider.

指定者:

getDescription 在接口中 CompressionProvider

返回:

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.

指定者:

getName 在接口中 CompressionProvider

返回:

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

getDefaultExtension

public String getDefaultExtension()

从接口复制的说明: CompressionProvider

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.)

指定者:

getDefaultExtension 在接口中 CompressionProvider

返回:

A String containing the default file extension for this provider
