Class OB

java.lang.Object

cdac.medinfo.sdk.dcm30_04.baselibs.DicomValue

cdac.medinfo.sdk.dcm30_04.baselibs.OB

All Implemented Interfaces:

IDicomValue, java.io.Serializable

public class OB
extends DicomValue

OB represents the string of bytes where the encoding of the contents is specified by the negotiated Transfer Syntax. OB is a VR which is insensitive to Little/Big Endian byte ordering The string of bytes shall be padded with a single trailing NULL byte value (00H) when necessary to achieve even length.

Method Detail

read

public boolean read(IDicomStream objIDicomStream,
           int iOBLength)
             throws InvalidDataTypeException,
                    java.io.IOException

This method reads OB in the structure -> OB Basic Offset Table with NO Item Value(Tag and Length) then Item Tag, length and value for each frame specified in the offset table3

Specified by:

read in interface IDicomValue

Specified by:

read in class DicomValue

Parameters:

objIDicomStream - stream from which the Item is to be written

iOBLength - length of the DicomValue to be read from the stream

Returns:

integer - returns status success/failure

Throws:

InvalidDataTypeException - If data type validation fails.

java.io.IOException - If Input/Output operation fails.

getMaxLength

public long getMaxLength()

Retrieves the max length for OB DataType

Returns:

integer - max length for OB DataType

write

public int write(IDicomStream objIDicomStream)
          throws java.io.IOException

This method writes the series of byte buffers present in the OB datatype. For this purpose it writes them in the structure specified in the Dicom standard.

Specified by:

write in interface IDicomValue

Specified by:

write in class DicomValue

Parameters:

objIDicomStream - stream on which to write the DataElements

Returns:

integer - status indicating success/failure

Throws:

java.io.IOException - If Input/Output operation fails.

validate

public boolean validate(java.lang.Object objValue)
                 throws ValidationException

Validates OB DataType

Specified by:

validate in interface IDicomValue

Specified by:

validate in class DicomValue

Parameters:

objValue - value of OB to be validated

Returns:

boolean status indicating success/failure

Throws:

ValidationException - If validation of DataType fails.

validate

public boolean validate()
                 throws ValidationException

Validates OB DataType

Specified by:

validate in interface IDicomValue

Specified by:

validate in class DicomValue

Parameters:

objValue - value of OB to be validated

Returns:

boolean status indicating success/failure

Throws:

ValidationException - If validation of DataType fails.

addItem

public void addItem(byte[] arrImage)

Adds pixel data in the form of raw buffer

Parameters:

arrImage - Byte array of raw image data.

getValueLength

public int getValueLength()

Retrieves the value length of the item. Note that this length excludes the Item major and minor tags

Specified by:

getValueLength in interface IDicomValue

Specified by:

getValueLength in class DicomValue

Returns:

integer - value length of the item

setValue

public void setValue(java.lang.Object objValue)
              throws InvalidDataTypeException

Sets the value in OB DataType

Specified by:

setValue in interface IDicomValue

Overrides:

setValue in class DicomValue

Parameters:

objValue - object of type Object representing the value of OB DataType

Throws:

InvalidDataTypeException - If data type validation fails.

dumpDICOMInfo

public void dumpDICOMInfo(IDicomStream objIDicomStream)
                   throws java.io.IOException

Dumps the value of Attribute as Hidden.

Parameters:

objIDicomStream - - the Stream on which the Data is to be written.

Throws:

java.io.IOException - - Exception is thrown indicating runtime failure of writing operation.

changeToUndefined

public void changeToUndefined()

This function sets the Value length to -1. If this function is called then then length of value is undefined length(-1)
