java.lang.Object
  com.pixelmed.dicom.Attribute
      com.pixelmed.dicom.OtherByteAttributeMultipleCompressedFilesOnDisk

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.

Though an instance of this class may be created using its constructors, there is also a factory class, AttributeFactory.

Constructor Summary

OtherByteAttributeMultipleCompressedFilesOnDisk(AttributeTag t)
Construct an (empty) attribute.

OtherByteAttributeMultipleCompressedFilesOnDisk(AttributeTag t, long vl, File[] files)
Read an attribute from a set of compressed files.

OtherByteAttributeMultipleCompressedFilesOnDisk(AttributeTag t, long vl, String[] fileNames)

Method Summary

long	getPaddedVL() Get the value length of this attribute, accounting for the need for even-length padding.
byte[]	getVR() Get the value representation of this attribute (OB).
void	removeValues() Remove any existing values, making the attribute empty (zero length).
String	toString(DicomDictionary dictionary) Dump the contents of the attribute as a human-readable string.
void	write(DicomOutputStream o) Write the entire attribute (including values) to the output stream.

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 class Attribute

Returns:

the value length (padded to an even length)

write

public void write(DicomOutputStream o)
           throws DicomException,
                  IOException

Description copied from class: Attribute

Write the entire attribute (including values) to the output stream.

Specified by:

write in class Attribute

Parameters:

o -

Throws:

IOException

DicomException

toString

public 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> <...>
 

For example:

 (0x0018,0x0020) ScanningSequence VR=<CS> VL=<0x2> <GR>
 

Overrides:

toString in class Attribute

Parameters:

dictionary - the dictionary to use to look up the name

Returns:

a single String value

removeValues

public void removeValues()

Description copied from class: Attribute

Remove any existing values, making the attribute empty (zero length).

Specified by:

removeValues in class Attribute

Throws:

DicomException

getVR

public byte[] getVR()

Get the value representation of this attribute (OB).

Overrides:

getVR in class Attribute

Returns:

'O','B' in ASCII as a two byte array; see ValueRepresentation
