Method Detail

closeQuietly

public static void closeQuietly(java.io.Closeable[] closeables)

Closes all Closeable objects from an array

Parameters:

closeables - an array of Closeable to be closed

closeQuietly

public static void closeQuietly(java.lang.Iterable<? extends java.io.Closeable> closeables)

Closes all Closeable objects from a Iterable

Parameters:

closeables - an Iterable of Closeable to be closed

closeQuietly

public static void closeQuietly(java.io.Closeable closeable)

Closes a Closeable object

Parameters:

closeable - the Closeable object to be closed

closeQuietly

public static void closeQuietly(java.net.Socket socket)

Closes a Socket object

Parameters:

socket - the Socket to be closed

isAndroidGetsocknameError

public static boolean isAndroidGetsocknameError(java.lang.AssertionError e)

Returns true if e is due to a firmware bug fixed after Android 4.2.2. https://code.google.com/p/android/issues/detail?id=54072

Parameters:

e - the suspected error

Returns:

true if error is due to firmware bug, false otherwise

skipAll

public static void skipAll(okio.Source source)
                    throws java.io.IOException

Goes through the Source and consumes all the contents

Parameters:

source - the Source to consume data from

Throws:

java.io.IOException - upon failed IO operations

skipAll

public static boolean skipAll(okio.Source source,
                              int duration,
                              java.util.concurrent.TimeUnit timeUnit)
                       throws java.io.IOException

Reads until in is exhausted or the deadline has been reached. This is careful to not extend the deadline if one exists already.

Parameters:

source - the target source to be exhausted

duration - the time available for exhaustion

timeUnit - the time unit of exhaustion time

Returns:

true if the source was exhausted without closing, false if time ran out

Throws:

java.io.IOException - on an IO error

readNumberLe

public static long readNumberLe(okio.BufferedSource source,
                                int byteCount)
                         throws java.io.IOException

Reads a number from the BufferedSource

Parameters:

source - the data source to read from

byteCount - the number of bytes to read

Returns:

the number extracted from the source

Throws:

java.io.IOException - on failed IO operations

peekNumberLe

public static long peekNumberLe(okio.BufferedSource source,
                                int offset,
                                int byteCount)
                         throws java.io.IOException

Peeks but does not consume a number from a BufferedSource

Parameters:

source - the data source to peek from

offset - marks where should the peeking begin

byteCount - the number of bytes to read

Returns:

the number extracted form the BufferedSource

Throws:

java.io.IOException - on failed IO operations

peekNumberLe

public static long peekNumberLe(okio.BufferedSource source,
                                int byteCount)
                         throws java.io.IOException

Peeks but does not consume a number from a BufferedSource

Parameters:

source - the data source to peek from

byteCount - the number of bytes to peek

Returns:

the number value extracted from the source

Throws:

java.io.IOException - on an IO error
