Static Methods

<S>deserialize(byte[] bytes)

public static S <S>deserialize(byte[] bytes)

Deserializes the given byte array into to a newly allocated object.

Parameter
Name	Description
`bytes`	`byte[]` byte array to deserialize or `null` for `null` result

Returns
Type	Description
`S`	new allocated object or `null` for `null` input

Exceptions
Type	Description
`IOException`

<S>deserialize(InputStream inputStream)

public static S <S>deserialize(InputStream inputStream)

Deserializes the given input stream into to a newly allocated object, and close the input stream.

Parameter
Name	Description
`inputStream`	`InputStream` input stream to deserialize

Returns
Type	Description
`S`

Exceptions
Type	Description
`IOException`

computeLength(StreamingContent content)

public static long computeLength(StreamingContent content)

Computes and returns the byte content length for a streaming content by calling StreamingContent#writeTo(OutputStream) on a fake output stream that only counts bytes written.

Parameter
Name	Description
`content`	`StreamingContent` streaming content

Returns
Type	Description
`long`

Exceptions
Type	Description
`IOException`

copy(InputStream inputStream, OutputStream outputStream) (deprecated)

public static void copy(InputStream inputStream, OutputStream outputStream)

Deprecated. use com.google.common.io.ByteStreams#copy(InputStream, OutputStream)

Writes the content provided by the given source input stream into the given destination output stream.

The input stream is guaranteed to be closed at the end of this method.

Sample use:

static void copy(InputStream inputStream, File file) throws IOException { FileOutputStream out = new FileOutputStream(file); try { IOUtils.copy(inputStream, out); } finally { out.close(); } }

Parameters
Name	Description
`inputStream`	`InputStream` source input stream
`outputStream`	`OutputStream` destination output stream

Exceptions
Type	Description
`IOException`

copy(InputStream inputStream, OutputStream outputStream, boolean closeInputStream) (deprecated)

public static void copy(InputStream inputStream, OutputStream outputStream, boolean closeInputStream)

Deprecated. use com.google.common.io.ByteStreams#copy(InputStream, OutputStream)

Writes the content provided by the given source input stream into the given destination output stream, optionally closing the input stream.

Sample use:

static void copy(InputStream inputStream, File file) throws IOException { FileOutputStream out = new FileOutputStream(file); try { IOUtils.copy(inputStream, out, true); } finally { out.close(); } }

Parameters
Name	Description
`inputStream`	`InputStream` source input stream
`outputStream`	`OutputStream` destination output stream
`closeInputStream`	`boolean` whether the input stream should be closed at the end of this method

Exceptions
Type	Description
`IOException`

isSymbolicLink(File file) (deprecated)

public static boolean isSymbolicLink(File file)

Deprecated. use java.nio.file.Path#isSymbolicLink

Returns whether the given file is a symbolic link.

Parameter
Name	Description
`file`	`File`

Returns
Type	Description
`boolean`

Exceptions
Type	Description
`IOException`

serialize(Object value)

public static byte[] serialize(Object value)

Serializes the given object value to a newly allocated byte array.

Parameter
Name	Description
`value`	`Object` object value to serialize

Returns
Type	Description
`byte[]`

Exceptions
Type	Description
`IOException`

serialize(Object value, OutputStream outputStream)

public static void serialize(Object value, OutputStream outputStream)

Serializes the given object value to an output stream, and close the output stream.

Parameters
Name	Description
`value`	`Object` object value to serialize
`outputStream`	`OutputStream` output stream to serialize into

Exceptions
Type	Description
`IOException`
