public class OtherByteAttributeMultipleCompressedFilesOnDisk extends Attribute
A concrete class specializing
Attribute
for Other Byte (OB) attributes whose values are not memory resident but rather are stored in multiple compressed files on disk.Whether or not decompression of compressed file format is supported is not checked until an attempt is made to write decompressed bytes.
Which decompressor to use is determined by the file name extension (.gz for gzip, .Z for unix compress, etc., case insensitive).

Method Detail
-
getPaddedVL
public long getPaddedVL()
Description copied from class:Attribute
Get the value length of this attribute, accounting for the need for even-length padding.
- Overrides:
getPaddedVL
in classAttribute
- Returns:
- the value length (padded to an even length)
-
write
public void write(DicomOutputStream o) throws DicomException, java.io.IOException
Description copied from class:Attribute
Write the entire attribute (including values) to the output stream.
- Specified by:
write
in classAttribute
- Parameters:
o
-- Throws:
java.io.IOException
DicomException
-
toString
public java.lang.String toString(DicomDictionary dictionary)
Description copied from class: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> <...>

- Specified by:
removeValues
in classAttribute
-
getVR
public byte[] getVR()
Get the value representation of this attribute (OB).
- Overrides:
getVR
in classAttribute
- Returns:
- 'O','B' in ASCII as a two byte array; see
ValueRepresentation
