Method Detail

toString

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

Converts the contents of an InputStream to a String using the specified Charset.

Note: The provided InputStream will not be closed by this method. It is the caller's responsibility to close the stream once processing is complete.

Parameters:

inputStream - the InputStream to read from

charset - the character encoding to use

Returns:

the decoded String representation of the InputStream's contents

Throws:

IOException - if an I/O error occurs while reading the InputStream

NullPointerException - if inputStream or charset is null

toByteArray

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

Reads the entire contents of an InputStream into a byte array.

Note: The provided InputStream will not be closed by this method. It is the caller's responsibility to close the stream once processing is complete.

Parameters:

inputStream - the InputStream to read from

Returns:

a byte array containing the data read from the InputStream

Throws:

IOException - if an I/O error occurs while reading the InputStream

NullPointerException - if inputStream is null

copy

public static void copy(InputStream inputStream,
                        OutputStream outputStream)
                 throws IOException

Copies the contents of an InputStream to an OutputStream.

Note: Neither the InputStream nor the OutputStream will be closed by this method. It is the caller's responsibility to close the streams once processing is complete.

Parameters:

inputStream - the InputStream to read from

outputStream - the OutputStream to write to

Throws:

IOException - if an I/O error occurs while reading or writing

NullPointerException - if inputStream or outputStream is null
