objIDictReader - DictionaryReader to read from the Dictionary

Throws:

InvalidTransferSyntaxException - Signals Transfer Syntax fails to satisfy Validation Criteria.

ImplicitDE

public ImplicitDE(int iGroupNumber,
          int iElementNumber,
          java.lang.Object objValue,
          IDictionaryReader objIDictReader)
           throws InvalidDataElementException

This constructor accepts dictionary reader reading from the dictionary populated using the DictioanryReader and sets the transfersyntax in the dataelement as a default transfersyntax

Parameters:

iGroupNumber - GroupNumber from the Tag identifying this DataElement

iElementNumber - ElementNumber from the Tah identifying this DataElement

objValue - value of the DataElement

objIDictReader - DictionaryReader to read from the Dictionary

Throws:

InvalidDataElementException - Signals Data Element fails to satisfy Validation Criteria.

ImplicitDE

public ImplicitDE(int iGroupNumber,
          int iElementNumber,

Method Detail

getDicomValue

public IDicomValue getDicomValue()

Retrieves the DicomValue present in the Implicit DataElement

Specified by:

getDicomValue in interface IDataElement

Overrides:

getDicomValue in class DataElement

Returns:

DicomValue - object of Dicom Data

parse

public int parse(IDicomStream objIDicomStream)
          throws InvalidDataElementException,
                 java.io.IOException

parse method reads the Tag,ValueLength,Data Value from the Stream. It gets the Value Representation(VR) for the Data Value from the Dictionary. It compares for the Value Multiplicity returned after reading the Data Value with Value Multiplicity read from Dictionary and sets it to the DataElement. Note : It could throw OutOfMemoryException if length exceeds from allowed Heap Space.

Specified by:

parse in interface IDataElement
