delete

public void delete(boolean pruneEmptyParentDirs)

Deletes the persistent resource backing this BLOBFileValue.

Specified by:

delete in class BLOBFileValue

Parameters:

pruneEmptyParentDirs - if true, empty parent directories will automatically be deleted

discard

public void discard()

Frees temporarily allocated resources such as temporary file, buffer, etc. If this BLOBFileValue is backed by a persistent resource calling this method will have no effect.

Specified by:

discard in class BLOBFileValue

isImmutable

public boolean isImmutable()

Checks if this object is immutable. Immutable objects can not change and can safely copied.

Specified by:

isImmutable in class BLOBFileValue

Returns:

true if the object is immutable

getLength

public long getLength()

Returns the length of this BLOBFileValue.

Specified by:

getLength in class BLOBFileValue

Returns:

The length, in bytes, of this BLOBFileValue, or -1L if the length can't be determined.

getStream

public InputStream getStream()
                      throws IllegalStateException,
                             RepositoryException

Returns an InputStream representation of this value.

Specified by:

getStream in class BLOBFileValue

Returns:

An InputStream representation of this value.

Throws:

IllegalStateException

RepositoryException

toString

public String toString()

Specified by:

toString in class BLOBFileValue

equals

public boolean equals(Object obj)

Specified by:

equals in class BLOBFileValue

hashCode

public int hashCode()

Returns zero to satisfy the Object equals/hashCode contract. This class is mutable and not meant to be used as a hash key.

Specified by:

hashCode in class BLOBFileValue

Returns:

always zero

isSmall

public boolean isSmall()

Check if the value is small (contains a low number of bytes) and should be stored inline.

Specified by:

isSmall in class BLOBFileValue

Returns:

true if the value is small
