## org.modeshape.jcr.value.binary
Interface BinaryStore

All Known Implementing Classes:
  AbstractBinaryStore, DatabaseBinaryStore, FileSystemBinaryStore, InfinispanBinaryStore, TransientBinaryStore

    @ThreadSafe
    public interface BinaryStore

The basic interface for a store for Binary value objects. All binary values that are of a `minimum threshold size` are stored in the store; smaller binary values are kept in-memory and are stored within the nodes.

Field Summary
`static long` | `DEFAULT_MINIMUM_BINARY_SIZE_IN_BYTES` The default minimum size (in bytes) of binary values that are persisted in the binary store is 4096 bytes, or 4KB.

Method Summary
`InputStream` | `getInputStream(BinaryKey key)` Get an `InputStream` to the binary content with the supplied key.
`String` | `getMimeType(BinaryValue binary, String name)` Get the MIME type for this binary value.
`long` | `getMinimumBinarySizeInBytes()` Get the minimum number of bytes that a binary value must contain before it can be stored in the binary store.
`String` | `getText(BinaryValue binary)` Get the text that can be extracted from this binary content.
`void` | `markAsUnused(Iterable<BinaryKey> keys)` Mark the supplied binary keys as unused, but key them in quarantine until needed again (at which point they're removed from quarantine) or until `removeValuesUnusedLongerThan(long, TimeUnit)` is called.
`void` | `removeValuesUnusedLongerThan(long minimumAge, TimeUnit unit)` Remove binary values that have been `unused` for at least the specified amount of time.
`void` | `setMimeTypeDetector(MimeTypeDetector mimeTypeDetector)` Set the MIME type detector that can be used for determining the MIME type for binary content.
`void` | `setMinimumBinarySizeInBytes(long minSizeInBytes)` Set the minimum number of bytes that a binary value must contain before it can be stored in the binary store.
`void` | `setTextExtractor(TextExtractor textExtractor)` Set the text extractor that can be used for extracting text from binary content.
`BinaryValue` | `storeValue(InputStream stream)` Store the binary value and return the JCR representation.

Field Detail

### DEFAULT_MINIMUM_BINARY_SIZE_IN_BYTES

    static final long DEFAULT_MINIMUM_BINARY_SIZE_IN_BYTES

  The default minimum size (in bytes) of binary values that are persisted in the binary store is 4096 bytes, or 4KB.

  See Also:
    Constant Field Values

Method Detail

### getMinimumBinarySizeInBytes

    long getMinimumBinarySizeInBytes()

  Get the minimum number of bytes that a binary value must contain before it can be stored in the binary store.

  Returns:
    the minimum number of bytes for a stored binary value; never negative

### setMinimumBinarySizeInBytes

    void setMinimumBinarySizeInBytes(long minSizeInBytes)

  Set the minimum number of bytes that a binary value must contain before it can be stored in the binary store.

  Parameters:
    `minSizeInBytes` - the minimum number of bytes for a stored binary value; may not be negative

### setTextExtractor

    void setTextExtractor(TextExtractor textExtractor)

  Set the text extractor that can be used for extracting text from binary content.

  Parameters:
    `textExtractor` - the text extractor

### setMimeTypeDetector

    void setMimeTypeDetector(MimeTypeDetector mimeTypeDetector)

  Set the MIME type detector that can be used for determining the MIME type for binary content.

  Parameters:
    `mimeTypeDetector` - the detector

### storeValue

    BinaryValue storeValue(InputStream stream)
                           throws BinaryStoreException

  Store the binary value and return the JCR representation. Note that if the binary content in the supplied stream is already persisted in the store, the store may simply return the binary value referencing the existing content.

  Parameters:
    `stream` - the stream containing the binary content to be stored; may not be null
  Returns:
    the binary value representing the stored binary value; never null
  Throws:
    `BinaryStoreException`

### getInputStream

    InputStream getInputStream(BinaryKey key)
                               throws BinaryStoreException

  Get an `InputStream` to the binary content with the supplied key.

  Parameters:
    `key` - the key to the binary content; never null
  Returns:
    the input stream through which the content can be read
  Throws:
    `BinaryStoreException` - if there is a problem reading the content from the store

### markAsUnused

    void markAsUnused(Iterable<BinaryKey> keys)
                      throws BinaryStoreException

  Mark the supplied binary keys as unused, but key them in quarantine until needed again (at which point they're removed from quarantine) or until `removeValuesUnusedLongerThan(long, TimeUnit)` is called. This method ignores any keys for values not stored within this store.

  Note that the implementation must never block.

  Parameters:
    `keys` - the keys for the binary values that are no longer needed
  Throws:
    `BinaryStoreException` - if there is a problem marking any of the supplied binary values as unused

### removeValuesUnusedLongerThan

    void removeValuesUnusedLongerThan(long minimumAge,
                                      TimeUnit unit)
                                      throws BinaryStoreException

  Remove binary values that have been `unused` for at least the specified amount of time.

  Note that the implementation must never block.

  Parameters:
    `minimumAge` - the minimum time that a binary value has been `unused` before it can be removed; must be non-negative
    `unit` - the time unit for the minimum age; may not be null
  Throws:
    `BinaryStoreException` - if there is a problem removing the unused values

### getText

    String getText(BinaryValue binary)
                   throws BinaryStoreException

  Get the text that can be extracted from this binary content.

  Parameters:
    `binary` - the binary content; may not be null
  Returns:
    the extracted text, or null if none could be extracted
  Throws:
    `BinaryStoreException` - if the binary content could not be accessed

### getMimeType

    String getMimeType(BinaryValue binary,
                       String name)
                       throws IOException,
                              RepositoryException

  Get the MIME type for this binary value.

  Parameters:
    `binary` - the binary content; may not be null
    `name` - the name of the content, useful for determining the MIME type; may be null if not known
  Returns:
    the MIME type, or null if it cannot be determined (e.g., the Binary is empty)
  Throws:
    `IOException` - if there is a problem reading the binary content
    `RepositoryException` - if an error occurs.
