Class TransientBinaryStore

java.lang.Object

org.modeshape.jcr.value.binary.AbstractBinaryStore

org.modeshape.jcr.value.binary.FileSystemBinaryStore

org.modeshape.jcr.value.binary.TransientBinaryStore

All Implemented Interfaces:

BinaryStore

@ThreadSafe
public final class TransientBinaryStore
extends FileSystemBinaryStore

A BinaryStore implementation that does not persist the binary values beyond the lifetime of the virtual machine. This implementation extends FileSystemBinaryStore and uses a temporary directory. Thus, the binary values are not stored in-memory.

Method Detail

get

public static TransientBinaryStore get()

Obtain a shared TransientBinaryStore instance.

Returns:

the instance; never null

start

public void start()

Description copied from interface: BinaryStore

Initialize the store and get ready for use.

Specified by:

start in interface BinaryStore

Overrides:

start in class AbstractBinaryStore

initializeStorage

protected void initializeStorage(File directory)
                          throws BinaryStoreException

Ensures that the directory used by this binary store exists and can be both read and written to.

Overrides:

initializeStorage in class FileSystemBinaryStore

Throws:

BinaryStoreException - if the directory cannot be written to, read, or (if needed) created

moveFileExclusively

protected void moveFileExclusively(File original,
                                   File destination,
                                   BinaryKey key)
                            throws BinaryStoreException

Overrides:

moveFileExclusively in class FileSystemBinaryStore

Throws:

BinaryStoreException
