public long[] getByteOffsets()
public byte[] getByteValues() throws DicomException
Get the values of this attribute as a byte 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.

public String toString(DicomDictionary dictionary)
Attribute
Dump the contents of the attribute as a human-readable string.
No new line is appended.
The result is of the form:
(0xgggg,0xeeee) Name VR=<XX> VL=<0xnnnn> <...>
For example:
(0x0018,0x0020) ScanningSequence VR=<CS> VL=<0x2> <GR>
