Constructor Detail

AttributeTagAttribute

public AttributeTagAttribute(AttributeTag t)

Construct an (empty) attribute.

Parameters:

t - the tag of the attribute

AttributeTagAttribute

public AttributeTagAttribute(AttributeTag t,
                             long vl,
                             DicomInputStream i)
                      throws IOException,
                             DicomException

Read an attribute from an input stream.

Parameters:

t - the tag of the attribute

vl - the value length of the attribute

i - the input stream

Throws:

IOException - if an I/O error occurs

DicomException - if error in DICOM encoding

AttributeTagAttribute

public AttributeTagAttribute(AttributeTag t,
                             Long vl,
                             DicomInputStream i)
                      throws IOException,
                             DicomException

Read an attribute from an input stream.

Parameters:

t - the tag of the attribute

vl - the value length of the attribute

i - the input stream

Throws:

IOException - if an I/O error occurs

DicomException - if error in DICOM encoding

Method Detail

addValue

public void addValue(AttributeTag t)
              throws DicomException

Parameters:

t - the tag

Throws:

DicomException - never thrown

addValue

public void addValue(int g,
                     int e)
              throws DicomException

Parameters:

g - group number

e - element number

Throws:

DicomException - never thrown

addValue

public void addValue(String s)
              throws DicomException

Description copied from class: Attribute

Add a(nother) String value after any existing values of this attribute.

Overrides:

addValue in class Attribute

Parameters:

s - a String of the form returned by toString(), i.e., "(0xgggg,0xeeee)" where gggg and eeee are the zero-padded hexadecimal representations of the group and element respectively

Throws:

DicomException - if String is not a valid representation of a tag

getAttributeTagValues

public AttributeTag[] getAttributeTagValues()
                                     throws DicomException

Returns:

the values

Throws:

DicomException - thrown if values are not available

getStringValues

public String[] getStringValues(NumberFormat format)
                         throws DicomException

Description copied from class: Attribute

Get the values of this attribute as strings.

The strings may have been cleaned up into a canonical form, such as to remove padding as well as numbers formatted.

Overrides:

getStringValues in class Attribute

Parameters:

format - the format to use for each numerical or decimal value

Returns:

the values as an array of String

Throws:

DicomException - thrown if values are not available (such as not supported for this concrete attribute class)

getVR

public byte[] getVR()

Get the value representation of this attribute (AT).

Overrides:

getVR in class Attribute

Returns:

'A','T' in ASCII as a two byte array; see ValueRepresentation

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

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

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 - the output stream

Throws:

DicomException - if error in DICOM encoding

IOException - if an I/O error occurs
