Constructor Detail
-
UnknownAttribute
public UnknownAttribute(AttributeTag t)
Construct an (empty) attribute.
- Parameters:
t
- the tag of the attribute
-
UnknownAttribute
public UnknownAttribute(AttributeTag t, long vl, DicomInputStream i) throws java.io.IOException, DicomException
Read an attribute from an input stream.
- Parameters:
t
- the tag of the attributevl
- the value length of the attributei
- the input stream- Throws:
java.io.IOException
DicomException
-
UnknownAttribute
public UnknownAttribute(AttributeTag t, java.lang.Long vl, DicomInputStream i) throws java.io.IOException, DicomException
Read an attribute from an input stream.
- Parameters:
t
- the tag of the attributevl
- the value length of the attributei
- the input stream- Throws:
java.io.IOException
DicomException
-

Method Detail
-
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> <...>
For example:
(0x0018,0x0020) ScanningSequence VR=<CS> VL=<0x2> <GR>
-
removeValues
public void removeValues()
Description copied from class:Attribute
Remove any existing values, making the attribute empty (zero length).
- Specified by:
removeValues
in classAttribute
-
getVR
public byte[] getVR()
Get the value representation of this attribute (UN).
- Overrides:
getVR
in classAttribute
- Returns:
- 'U','U' in ASCII as a two byte array; see
ValueRepresentation
-
getByteValues
public byte[] getByteValues()
Get the values of this attribute as a byte array.
Always to be interpreted as little endian, per the DICOM definition of UN, regardless of the received transfer syntax.
- Overrides:
getByteValues
in classAttribute
- Returns:
- the values as an array of bytes
-
getStringValues
public java.lang.String[] getStringValues(java.text.NumberFormat format) throws DicomException
Get the values of this attribute as strings.
Assumes the caller knows that the UN VR is really a valid string (e.g., knows the VR of a private attribute).
Assumes ASCII encoding (i.e., does not consider SpecificCharacterSet).
The strings are first cleaned up into a canonical form, to remove leading and trailing padding.
- Overrides:
getStringValues
in classAttribute
- Parameters:
format
- the format to use for each numerical or decimal value - ignored- Returns:
- the values as an array of
String
- Throws:
DicomException
- not thrown
-
getDoubleValues
public double[] getDoubleValues() throws DicomException
Get the values of this attribute as doubles.
Assumes the caller knows that the UN VR is really a valid FD (e.g., knows the VR of a private attribute).
- Overrides:
getDoubleValues
in classAttribute
- Returns:
- the values as an array of double
- Throws:
DicomException
-
getFloatValues
public float[] getFloatValues() throws DicomException
Get the values of this attribute as floats.
Assumes the caller knows that the UN VR is really a valid FL (e.g., knows the VR of a private attribute).
- Overrides:
getFloatValues
in classAttribute
- Returns:
- the values as an array of float
- Throws:
DicomException
