所有已实现的接口:

Closeable, AutoCloseable

封闭类:

HTTPServer

public static class HTTPServer.MultipartInputStream
extends FilterInputStream

The MultipartInputStream decodes an InputStream whose data has a "multipart/*" content type (see RFC 2046), providing the underlying data of its various parts.

The InputStream methods (e.g. read()) relate only to the current part, and the nextPart() method advances to the beginning of the next part.

构造器详细资料

MultipartInputStream

protected MultipartInputStream(InputStream in,
                               byte[] boundary)

Constructs a MultipartInputStream with the given underlying stream.

参数:

in - the underlying multipart stream

boundary - the multipart boundary

抛出:

NullPointerException - if the given stream or boundary is null

IllegalArgumentException - if the given boundary's size is not between 1 and 70

read

public int read()
         throws IOException

覆盖:

read 在类中 FilterInputStream

抛出:

IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

覆盖:

read 在类中 FilterInputStream

抛出:

IOException

skip

public long skip(long len)
          throws IOException

覆盖:

skip 在类中 FilterInputStream

抛出:

IOException

available

public int available()
              throws IOException

覆盖:

available 在类中 FilterInputStream

抛出:

IOException

markSupported

public boolean markSupported()

覆盖:

markSupported 在类中 FilterInputStream

nextPart

public boolean nextPart()
                 throws IOException

Advances the stream position to the beginning of the next part. Data read before calling this method for the first time is the preamble, and data read after this method returns false is the epilogue.

返回:

true if successful, or false if there are no more parts

抛出:

IOException - if an error occurs

fill

protected boolean fill()
                throws IOException

Fills the buffer with more data from the underlying stream.

返回:

true if there is available data for the current part, or false if the current part's end has been reached

抛出:

IOException - if an error occurs or the input format is invalid

findBoundary

protected void findBoundary()
                     throws IOException

Finds the first (potential) boundary within the buffer's remaining data. Updates tail, length and state fields accordingly.

抛出:

IOException - if an error occurs or the input format is invalid
