Method Detail

copyStream

public static void copyStream(InputStream input,
              OutputStream output)
                       throws IOException

Copy the data from an InputStream to an OutputStream without closing the stream.

Throws:

IOException

copyStream

public static void copyStream(InputStream input,
              OutputStream output,
              int bufferSize)
                       throws IOException

Copy the data from an InputStream to an OutputStream without closing the stream.

Throws:

IOException

copyStreamToByteArray

public static byte[] copyStreamToByteArray(InputStream input)
                                    throws IOException

Copy the data from an InputStream to a byte array without closing the stream.

Throws:

IOException

copyStreamToByteArray

public static byte[] copyStreamToByteArray(InputStream input,
                           int estimatedSize)
                                    throws IOException

Copy the data from an InputStream to a byte array without closing the stream.

Parameters:

estimatedSize - Used to preallocate a possibly correct sized byte array to avoid an array copy.

Throws:

IOException

copyStreamToString

public static String copyStreamToString(InputStream input)
                                 throws IOException

Copy the data from an InputStream to a string using the default charset without closing the stream.

Throws:

IOException

copyStreamToString

public static String copyStreamToString(InputStream input,
                        int approxStringLength)
                                 throws IOException

Copy the data from an InputStream to a string using the default charset.

Parameters:

approxStringLength - Used to preallocate a possibly correct sized StringBulder to avoid an array copy.

Throws:

IOException

closeQuietly

public static void closeQuietly(Closeable c)

Close and ignore all errors.
