Method Details

toByteArray

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

Reads and returns the rest of the given input stream as a byte array. Caller is responsible for closing the given input stream.

Throws:

IOException

toUtf8String

public static String toUtf8String(InputStream is)
                           throws IOException

Reads and returns the rest of the given input stream as a string. Caller is responsible for closing the given input stream.

Throws:

IOException

closeQuietly

public static void closeQuietly(AutoCloseable is,
 org.slf4j.Logger log)

Closes the given Closeable quietly.

Parameters:

is - the given closeable

log - logger used to log any failure should the close fail

closeIfCloseable

public static void closeIfCloseable(Object maybeCloseable,
 org.slf4j.Logger log)

Closes the given Closeable quietly.

Parameters:

maybeCloseable - the given closeable

log - logger used to log any failure should the close fail

copy

public static long copy(InputStream in,
 OutputStream out)
                 throws IOException

Copies all bytes from the given input stream to the given output stream. Caller is responsible for closing the streams.

Throws:

IOException - if there is any IO exception during read or write.

copy

public static long copy(InputStream in,
 OutputStream out,
 long readLimit)
                 throws IOException

Copies all bytes from the given input stream to the given output stream. Caller is responsible for closing the streams.

Throws:

IOException - if there is any IO exception during read or write or the read limit is exceeded.

drainInputStream

public static void drainInputStream(InputStream in)

Read all remaining data in the stream.

Parameters:

in - InputStream to read.

markStreamWithMaxReadLimit

public static void markStreamWithMaxReadLimit(InputStream s)

If the stream supports marking, marks the stream at the current position with a readLimit value of 128 KiB.

Parameters:

s - The stream.

markStreamWithMaxReadLimit

public static void markStreamWithMaxReadLimit(InputStream s,
 Integer maxReadLimit)

If the stream supports marking, marks the stream at the current position with a read limit specified in maxReadLimit.

Parameters:

s - The stream.

maxReadLimit - the maxReadLimit, if it's null, 128 KiB will be used.
