Method Detail

readLine

public static java.lang.String readLine(java.io.InputStream inputStream)
                                 throws java.io.IOException

Read a line of bytes from an InputStream. Useful when an InputStream may contain both text and binary data.

Parameters:

inputStream - A source of data

Returns:

A line of text read from inputStream, with terminating \r\n or \n removed, or null if no data is available.

Throws:

java.io.IOException - on trouble reading from input stream

readRawLine

public static byte[] readRawLine(java.io.InputStream inputStream)
                          throws java.io.IOException

Reads a raw line from an InputStream, up till \n. Since HTTP allows \r\n and \n as terminators, this gets the whole line. This code is adapted from org.apache.commons.httpclient.HttpParser

Parameters:

inputStream - A stream to read from.

Returns:

Array of bytes read or null if none are available.

Throws:

java.io.IOException - if the underlying reads fail
