Method Detail

copyStreamToStream

public static boolean copyStreamToStream(java.io.InputStream inStream,
                                         java.io.OutputStream outStream)

Copies an input stream to the output stream until end of stream. This won't close the streams!! You have to close them.

Parameters:

inStream -

outStream -

Returns:

copyStreamToString

public static java.lang.String copyStreamToString(java.io.InputStream inStream)

Copies an input stream to a string until end of stream. This won't close the stream!! You have to close them.

Parameters:

inStream -

Returns:

copyStreamToFile

public static boolean copyStreamToFile(java.io.InputStream inStream,
                                       java.io.File outFile)

Copies an input stream to a file until end of stream. This won't close the stream!! You have to close them. This will overwrite the file.

Parameters:

inStream -

outFile -

Returns:

copyStreamToFile

public static boolean copyStreamToFile(java.io.InputStream inStream,
                                       java.io.File outFile,
                                       boolean append)

Copies an input stream to a file until end of stream. This won't close the stream!! You have to close them.

Parameters:

inStream -

outFile -

append -

Returns:

copyStreamToTempFile

public static java.io.File copyStreamToTempFile(java.io.InputStream inStream)

Copies an input stream to a temporary file until end of stream. This won't close the stream!! You have to close them.

Parameters:

inStream -

Returns:

ensureRead

public static int ensureRead(java.io.InputStream in,
                             byte[] b,
                             int off,
                             int len)
                      throws java.io.IOException

Works similarly to InputStream but ensures that len is read, or returns -1 if EOS.

Parameters:

in - the InputStream to read from.

b - the buffer into which the data is read.

off - the start offset in array b at which the data is written.

len - The maximum number of bytes to read.

Returns:

The total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.

Throws:

java.io.IOException
