方法详细资料

getInputStream

InputStream getInputStream()
                    throws IOException

Get the content of the resource as input stream.

返回:

input stream of Resource content

抛出:

IOException - If an input exception occurs

getReader

default Reader getReader()
                  throws IOException

Get Reader

抛出:

IOException - If an input exception occurs

getReader

default Reader getReader(String encoding)
                  throws IOException

Get Reader

参数:

encoding - Charset string

抛出:

IOException - If an input exception occurs

readableChannel

default ReadableByteChannel readableChannel()
                                     throws IOException

Return a ReadableByteChannel.

It is expected that each call creates a fresh channel.

The default implementation returns Channels.newChannel(InputStream) with the result of getInputStream().

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
