C# Class ClearCanvas.ImageViewer.StudyManagement.Sop

A DICOM SOP Instance.

Note that there should no longer be any need to derive from this class; the Sop, ImageSop and Frame classes are now just simple Bridge classes (see Bridge Design Pattern) to ISopDataSource and ISopFrameData. See the remarks for ISopDataSource for more information.

Also, for more information on 'transient references' and the lifetime of Sops, see ISopReference.

Public Methods

Method	Description
Create ( ISopDataSource dataSource ) : Sop	Creates either a Sop or ImageSop based on the SopClass of the given ISopDataSource.
Create ( string filename ) : Sop	Creates either a Sop or ImageSop based on the SopClass of the SOP instance specified by filename.
GetIdentifier ( ) : IImageIdentifier	Gets an IImageIdentifier for this Sop. An IImageIdentifier can be used in situations where you only need some data about the Sop, but not the Sop itself. It can be problematic to hold references to Sop objects outside the context of an IImageViewer without creating a transient reference because they are no longer valid when the viewer is closed; in these situations, it may be appropriate to use an identifier.
ResetCache ( ) : void	Resets any values that were cached after reading from DataSource. Many of the property values are cached for performance reasons, as they generally never change, and parsing values from the image header can be expensive, especially when done repeatedly.
Sop ( ISopDataSource dataSource ) : System	Creates a new instance of Sop.
Sop ( string filename ) : System	Creates a new instance of Sop from a local file.
ToString ( ) : string	Returns the SOP instance UID in string form.
TryGetAttribute ( ClearCanvas.Dicom.DicomTag tag, ClearCanvas.Dicom.DicomAttribute &dicomAttribute ) : bool	Gets a specific DICOM attribute in the underlying native object. DicomAttributes returned from this indexer are considered read-only and should not be modified in any way.
TryGetAttribute ( uint tag, ClearCanvas.Dicom.DicomAttribute &dicomAttribute ) : bool	Gets a specific DICOM attribute in the underlying native object. DicomAttributes returned from this indexer are considered read-only and should not be modified in any way.
Validate ( ) : void	The Sop class (and derived classes) should not validate tag values from within its properties, but instead clients should call this method at an appropriate time to determine whether or not the Sop should be used or discarded as invalid.
ValidateAllowableTransferSyntax ( ) : void
this ( ClearCanvas.Dicom.DicomTag tag ) : ClearCanvas.Dicom.DicomAttribute	Gets a specific DICOM attribute in the underlying native object. DicomAttributes returned from this indexer are considered read-only and should not be modified in any way.
this ( uint tag ) : ClearCanvas.Dicom.DicomAttribute	Gets a specific DICOM attribute in the underlying native object. DicomAttributes returned from this indexer are considered read-only and should not be modified in any way.

Protected Methods

Method	Description
Dispose ( bool disposing ) : void	Disposes all resources being used by this Sop.
GetAllowableTransferSyntaxes ( ) : IEnumerable
ValidateInternal ( ) : void	Validates the Sop object. Derived classes should call the base class implementation first, and then do further validation. The Sop class validates properties deemed vital to usage of the object.

Method Details

Create() public static method

Creates either a Sop or ImageSop based on the SopClass of the given ISopDataSource.

public static Create ( ISopDataSource dataSource ) : Sop
dataSource	ISopDataSource
return	Sop

Create() public static method

Creates either a Sop or ImageSop based on the SopClass of the SOP instance specified by filename.

public static Create ( string filename ) : Sop
filename	string
return	Sop

Dispose() protected method

Disposes all resources being used by this Sop.

protected Dispose ( bool disposing ) : void
disposing	bool
return	void

GetAllowableTransferSyntaxes() protected method

protected GetAllowableTransferSyntaxes ( ) : IEnumerable
return	IEnumerable

GetIdentifier() public method

Gets an IImageIdentifier for this Sop.

An IImageIdentifier can be used in situations where you only need some data about the Sop, but not the Sop itself. It can be problematic to hold references to Sop objects outside the context of an IImageViewer without creating a transient reference because they are no longer valid when the viewer is closed; in these situations, it may be appropriate to use an identifier.

public GetIdentifier ( ) : IImageIdentifier
return	IImageIdentifier

ResetCache() public method

Resets any values that were cached after reading from DataSource.

Many of the property values are cached for performance reasons, as they generally never change, and parsing values from the image header can be expensive, especially when done repeatedly.

public ResetCache ( ) : void
return	void

Sop() public method

Creates a new instance of Sop.

public Sop ( ISopDataSource dataSource ) : System
dataSource	ISopDataSource
return	System

Sop() public method

Creates a new instance of Sop from a local file.

public Sop ( string filename ) : System
filename	string	The path to a local DICOM Part 10 file.
return	System

ToString() public method

Returns the SOP instance UID in string form.

public ToString ( ) : string
return	string

TryGetAttribute() public method

Gets a specific DICOM attribute in the underlying native object.

DicomAttributes returned from this indexer are considered read-only and should not be modified in any way.

Thrown if the specified DICOM tag is not within the valid range for either the meta info or the dataset.

public TryGetAttribute ( ClearCanvas.Dicom.DicomTag tag, ClearCanvas.Dicom.DicomAttribute &dicomAttribute ) : bool
tag	ClearCanvas.Dicom.DicomTag	The DICOM tag of the attribute to retrieve.
dicomAttribute	ClearCanvas.Dicom.DicomAttribute	Returns the requested .
return	bool

TryGetAttribute() public method

Gets a specific DICOM attribute in the underlying native object.

DicomAttributes returned from this indexer are considered read-only and should not be modified in any way.

Thrown if the specified DICOM tag is not within the valid range for either the meta info or the dataset.

public TryGetAttribute ( uint tag, ClearCanvas.Dicom.DicomAttribute &dicomAttribute ) : bool
tag	uint	The DICOM tag of the attribute to retrieve.
dicomAttribute	ClearCanvas.Dicom.DicomAttribute	Returns the requested .
return	bool

Validate() public method

The Sop class (and derived classes) should not validate tag values from within its properties, but instead clients should call this method at an appropriate time to determine whether or not the Sop should be used or discarded as invalid.

Thrown when validation fails.

public Validate ( ) : void
return	void

ValidateAllowableTransferSyntax() public method

public ValidateAllowableTransferSyntax ( ) : void
return	void

ValidateInternal() protected method
