public class OtherWordAttributeOnDisk extends OtherAttributeOnDisk
A concrete class specializing Attribute
for
Other Word (OW) attributes whose values are not memory resident.
Though an instance of this class may be created
using its constructors, there is also a factory class, AttributeFactory
.

public boolean isBigEndian()
Is the data on disk byte order big endian ?
public short[] getShortValues() throws DicomException
Get the values of this attribute as a short array.
This allocates a new array of sufficient length, which may fail if it is too large,
and defeats the point of leaving the byte values on disk in the first place. However, it
is a fallback for when the caller does not want to go to the trouble of creating a
MappedByteBuffer
from the file,
or more likely is not even aware that the attribute values have been left on disk, because
AttributeFactory
silently created an instance of this
class rather than an in-memory OtherWordAttribute
.
