Method Details

closeQuietly

public static void closeQuietly(AutoCloseable closeable)

Unconditionally close a AutoCloseable.

Equivalent to AutoCloseable.close(), except any exceptions will be ignored.

Parameters:

closeable - the object to close, may be null or already closed

copyAndClose

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

Copy bytes from InputStream to an OutputStream and close them after.

Parameters:

input - the InputStream to read from

output - the OutputStream to write to

Throws:

NullPointerException - if the input or output is null

IOException - if an I/O error occurs

copy

public static void copy(InputStream input,
 OutputStream output,
 byte[] buffer)
                 throws IOException

Copy bytes from InputStream to an OutputStream.

This method uses the provided buffer, so there is no need to use a BufferedInputStream.

Parameters:

input - the InputStream to read from

output - the OutputStream to write to

buffer - the buffer to use for the copy

Throws:

NullPointerException - if the input or output is null

IOException - if an I/O error occurs

toInputStream

public static InputStream toInputStream(CharSequence input)

Convert the specified CharSequence to an input stream, encoded as bytes using UTF-8 character encoding.

Parameters:

input - the CharSequence to convert

Returns:

an input stream
