public WritableResourceDecorator(Resource delegate)

方法详细资料

getOutputStream

public OutputStream getOutputStream()
                             throws IOException

从接口复制的说明: OutputStreamSource

Return an OutputStream for the underlying resource, allowing to (over-)write its content.

指定者:

getOutputStream 在接口中 OutputStreamSource

抛出:

IOException - if the stream could not be opened

getWriter

public Writer getWriter()
                 throws IOException

从接口复制的说明: OutputStreamSource

Get Writer

指定者:

getWriter 在接口中 OutputStreamSource

抛出:

IOException - if the stream could not be opened

writableChannel

public WritableByteChannel writableChannel()
                                    throws IOException

从接口复制的说明: OutputStreamSource

Return a WritableByteChannel.

It is expected that each call creates a fresh channel.

The default implementation returns Channels.newChannel(OutputStream) with the result of OutputStreamSource.getOutputStream().

指定者:

writableChannel 在接口中 OutputStreamSource

返回:

the byte channel for the underlying resource (must not be null)

抛出:

FileNotFoundException - if the underlying resource doesn't exist

IOException - if the content channel could not be opened

另请参阅:

• OutputStreamSource.getOutputStream()

isWritable

public boolean isWritable()

从接口复制的说明: WritableResource

Indicate whether the contents of this resource can be written via OutputStreamSource.getOutputStream().

Will be true for typical resource descriptors; note that actual content writing may still fail when attempted. However, a value of false is a definitive indication that the resource content cannot be modified.

指定者:

isWritable 在接口中 WritableResource

另请参阅:

• OutputStreamSource.getOutputStream()
• Resource.isReadable()

writableResource

protected WritableResource writableResource()

抛出:

UnsupportedOperationException - not a WritableResource
