DefaultBinaryManager (Nuxeo 2021.1.19 API Documentation)

java.lang.Object
- org.nuxeo.ecm.core.blob.binary.AbstractBinaryManager
- - org.nuxeo.ecm.core.blob.binary.LocalBinaryManager
  - - org.nuxeo.ecm.core.blob.binary.DefaultBinaryManager

All Implemented Interfaces:

BinaryManager
```
public class DefaultBinaryManager
extends LocalBinaryManager
```
A simple filesystem-based binary manager. It stores the binaries according to their digest (hash), which means that no transactional behavior needs to be implemented.
A garbage collection is needed to purge unused binaries.
The format of the binaries directory is:
- data/ hierarchy with the actual binaries in subdirectories,
- tmp/ temporary storage during creation,
- config.xml a file containing the configuration used.

    Description copied from interface: BinaryManager
    
    Saves the given blob into a Binary.
    Returns a Binary representing the stream. The Binary includes a digest that is a sufficient representation to persist it.
    If the blob is a temporary FileBlob, then the temporary file may be reused as the final storage location after being moved.
    
    Specified by:
    
    getBinary in interface BinaryManager
    
    Overrides:
    
    getBinary in class AbstractBinaryManager
    
    Parameters:
    
    blob - the blob
    
    Returns:
    
    the corresponding binary
    
    Throws:
    
    IOException
  - storeAndDigest
```
protected String storeAndDigest(FileBlob blob)
                         throws IOException
```
    Stores and digests a temporary FileBlob.
    
    Throws:
    
    IOException
