Class SerializableFileReference

java.lang.Object

nl.nn.adapterframework.stream.SerializableFileReference

All Implemented Interfaces:

Serializable, AutoCloseable

public class SerializableFileReference
extends Object
implements Serializable, AutoCloseable

A reference to a file Path that can be serialized. When serialized it will write all the file data to the serialization stream. When deserialized, it will copy all file-data to a new temporary file.

Constructor Detail

SerializableFileReference

public SerializableFileReference(Path path)

Create a binary SerializableFileReference for the file at given path.

The file will be not deleted on calling close().

Parameters:

path - Path to the file being referenced.

SerializableFileReference

public SerializableFileReference(Path path,
                                 boolean deleteOnClose)

Create a binary SerializableFileReference for the file at given path.

Parameters:

path - Path to the file being referenced.

deleteOnClose - if the temporary file will be deleted on calling close().

SerializableFileReference

public SerializableFileReference(String charset,
                                 Path path)

Create a character-data SerializableFileReference for the file at given path.

The file will be not deleted on calling close().

Parameters:

charset - Character set to be used when reading the file.

path - Path to the file being referenced.

Method Detail

of

public static SerializableFileReference of(InputStream in)
                                    throws IOException

Create a new SerializableFileReference from the given InputStream. The InputStream will be copied to a temporary file on disk and will be closed afterward. The SerializableFileReference will be treated as binary data.

The temporary file will be deleted on calling close().

Parameters:

in - The InputStream from which to create the SerializableFileReference. Will be closed after completion of this method.

Returns:

A new binary SerializableFileReference.

Throws:

IOException - If the InputStream cannot be read or a temporary file cannot be created / written to.

of

public static SerializableFileReference of(byte[] data)
                                    throws IOException

Create a new SerializableFileReference from the given byte[]. The byte[] will be copied to a temporary file on disk. The SerializableFileReference will be treated as binary data.

The temporary file will be deleted on calling close().

Parameters:

data - The byte[] from which to create the SerializableFileReference.

Returns:

A new binary SerializableFileReference.

Throws:

IOException - If the byte[] cannot be written to a temporary file.

of

public static SerializableFileReference of(Reader in,
                                           String charset)
                                    throws IOException

Create a new SerializableFileReference from the given Reader. The Reader will be copied to a temporary file on disk and will be closed afterward. The SerializableFileReference will be treated as character data.

The temporary file will be deleted on calling close().

Parameters:

in - The Reader from which to create the SerializableFileReference. Will be closed after completion of this method.

charset - Character set of the data in the Reader.

Returns:

A new character-data SerializableFileReference.

Throws:

IOException - If the Reader cannot be read or a temporary file cannot be created / written to.

of

public static SerializableFileReference of(String data,
                                           String charset)
                                    throws IOException

Create a new SerializableFileReference from the given String. The String will be copied to a temporary file on disk. The SerializableFileReference will be treated as character data.

The temporary file will be deleted on calling close().

Parameters:

data - The String from which to create the SerializableFileReference.

charset - Character used for writing out and reading back the data.

Returns:

A new character-data SerializableFileReference.

Throws:

IOException - If the String data cannot be written to a temporary file.
