public class RequestStream
extends javax.servlet.ServletInputStream

Convenience implementation of ServletInputStream that works with the standard implementations of Request. If the content length has been set on our associated Request, this implementation will enforce not reading more than that many bytes on the underlying stream.

closed

protected boolean closed
Has this stream been closed?

count

protected int count
The number of bytes which have already been returned by this stream.

length

protected int length
The content length past which we will not read, or -1 if there is no defined content length.

コンストラクタの詳細

RequestStream

public RequestStream(Request request)
Construct a servlet input stream associated with the specified Request.
パラメータ:
request - The associated request
メソッドの詳細

close

public void close()
           throws java.io.IOException
Close this input stream. No physical level I-O is performed, but any further attempt to read from this stream will throw an IOException. If a content length has been set but not all of the bytes have yet been consumed, the remaining bytes will be swallowed.
オーバーライド:
クラス java.io.InputStream 内の close

read

public int read()
         throws java.io.IOException
Read and return a single byte from this input stream, or -1 if end of file has been encountered.
オーバーライド:
クラス java.io.InputStream 内の read
例外:
java.io.IOException - if an input/output error occurs

read

public int read(byte[] b)
         throws java.io.IOException
Read some number of bytes from the input stream, and store them into the buffer array b. The number of bytes actually read is returned as an integer. This method blocks until input data is available, end of file is detected, or an exception is thrown.
オーバーライド:
クラス java.io.InputStream 内の read
パラメータ:
b - The buffer into which the data is read
例外:
java.io.IOException - if an input/output error occurs

read

public int read(byte[] b,
                int off,
                int len)
         throws java.io.IOException
Read up to len bytes of data from the input stream into an array of bytes. An attempt is made to read as many as len bytes, but a smaller number may be read, possibly zero. The number of bytes actually read is returned as an integer. This method blocks until input data is available, end of file is detected, or an exception is thrown.
オーバーライド:
クラス java.io.InputStream 内の read
パラメータ:
b - The buffer into which the data is read
off - The start offset into array b at which the data is written
len - The maximum number of bytes to read
例外:
java.io.IOException - if an input/output error occurs
