public class IdentityMessageBodyInputStream
extends java.io.InputStream
Identity input stream. Wraps an InputStream and all of the operations on
IdentityMessageBodyInputStream are delegated to this underlying InputStream.
| Constructor and Description |
|---|
IdentityMessageBodyInputStream(java.io.InputStream is,
int bodyLength)
Creates a new instance of
IdentityMessageBodyInputStream with the InputStream is
with the predefined length bodyLength. |
| Modifier and Type | Method and Description |
|---|---|
int |
available()
Returns the number of bytes that can be read (or skipped over) from this input stream without blocking.
|
void |
close()
Reads all remaining message body data and then close this input stream.
|
int |
read()
Reads the next byte of data from the input stream.
|
int |
read(byte[] data,
int offset,
int length)
Reads up to
length bytes of data from the underlying InputStream into an array of bytes. |
public IdentityMessageBodyInputStream(java.io.InputStream is,
int bodyLength)
Creates a new instance of IdentityMessageBodyInputStream with the InputStream is
with the predefined length bodyLength. The bodyLength should be the maximum number of
bytes can be read from the InputStream.
is - the underlying InputStream to read the body content of the HTTP message bodybodyLength - the number of bytes can be read from the underlying InputStream.public int available()
throws java.io.IOException
Returns the number of bytes that can be read (or skipped over) from this input stream without blocking.
available in class java.io.InputStreamjava.io.IOException - if IO Error occurs.public void close()
throws java.io.IOException
Reads all remaining message body data and then close this input stream. This method DOES NOT close the underlying stream (i.e. the TCP connection stream). It is the responsibility of the HTTPSession to close the underlying stream.

throws java.io.IOException
Reads the next byte of data from the input stream. The byte value is returned as an int in the range of 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.
read in class java.io.InputStreamjava.io.IOException - If a premature EOF is reached, this stream is closed and an IOException is thrown.public int read(byte[] data,
int offset,
int length)
throws java.io.IOException
Reads up to length bytes of data from the underlying InputStream into an array of bytes. An
attempt is made to read as many as length bytes, but the amount of bytes can be read from the
InputStream could be less than length, even 0. The number of bytes actually
read are returned as an integer.
