```
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 class Attribute
    
    Parameters:

    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>
    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
  - getVR
```
public byte[] getVR()
```
    Get the value representation of this attribute (UN).
    
    Overrides:
    
    getVR in class Attribute
    
    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 class Attribute
    
    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 class Attribute
    
    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

                         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 class Attribute
    
    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 class Attribute
    
    Returns:
    
    the values as an array of float
