HTTPServer

public static class HTTPServer.ChunkedOutputStream
extends FilterOutputStream

The ChunkedOutputStream encodes an OutputStream with the "chunked" transfer encoding. It should be used only when the content length is not known in advance, and with the response Transfer-Encoding header set to "chunked".

Data is written to the stream by calling the write(byte[], int, int) method, which writes a new chunk per invocation. To end the stream, the writeTrailingChunk(org.noear.solon.boot.jlhttp.HTTPServer.Headers) method must be called or the stream closed.

ChunkedOutputStream

public ChunkedOutputStream(OutputStream out)

Constructs a ChunkedOutputStream with the given underlying stream.

参数:

out - the underlying output stream to which the chunked stream is written

抛出:

NullPointerException - if the given stream is null

方法详细资料

initChunk

protected void initChunk(long size)
                  throws IOException

Initializes a new chunk with the given size.

参数:

size - the chunk size (must be positive)

抛出:

IllegalArgumentException - if size is negative

IOException - if an IO error occurs, or the stream has already been ended

writeTrailingChunk

public void writeTrailingChunk(HTTPServer.Headers headers)
                        throws IOException

Writes the trailing chunk which marks the end of the stream.

参数:

headers - the (optional) trailing headers to write, or null

抛出:

IOException - if an error occurs

write

public void write(int b)
           throws IOException

Writes a chunk containing the given byte. This method initializes a new chunk of size 1, and then writes the byte as the chunk data.

覆盖:

write 在类中 FilterOutputStream

参数:

b - the byte to write as a chunk

抛出:

IOException - if an error occurs

write

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

Writes a chunk containing the given bytes. This method initializes a new chunk of the given size, and then writes the chunk data.

覆盖:

write 在类中 FilterOutputStream

参数:

b - an array containing the bytes to write

off - the offset within the array where the data starts

len - the length of the data in bytes

抛出:

IOException - if an error occurs

IndexOutOfBoundsException - if the given offset or length are outside the bounds of the given array

close

public void close()
           throws IOException

Writes the trailing chunk if necessary, and closes the underlying stream.

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

覆盖:

close 在类中 FilterOutputStream

抛出:

IOException - if an error occurs
