Method Details

stream

public static long stream(InputStream inputStream,
 OutputStream outputStream,
 int bufferSize)
                   throws IOException

Streams an InputStream completely to an OutputStream. The binary data from inputStream will be stored to outputStream in chunks of the size bufferSize until the end of inputStream is reached.

Parameters:

inputStream - the input stream to read from

outputStream - the output stream to write to

bufferSize - the size of the chunks to use

Returns:

the number of bytes streamed

Throws:

IOException

convertInputStreamToByteArray

public static byte[] convertInputStreamToByteArray(InputStream inputStream)
                                            throws IOException

Returns the content of the specified InputStream as a byte[], which has exactly the size of the content.

The specified InputStream must not be null.

Parameters:

inputStream - InputStream to convert into a byte[]

Returns:

byte[] with the content of the specified InputStream

Throws:

IOException - on errors reading the inputStream

convertInputStreamToString

public static String convertInputStreamToString(InputStream inputStream,
 Charset charset)
                                         throws IOException

Reads the content of the specified InputStream to a byte[], which will then be interpreted as String with the given encoding.

Parameters:

inputStream - InputStream the input stream to read from

charset - the Charset to decode the bytes to a String. Must not be null.

Returns:

a String being the content of the given InputStream

Throws:

IOException
