message.getDICOMSignedLongs

Use when: You want to read values from the modified message during mapping. If you need the original incoming message, use source.getDICOMSignedLongs.

Signature: message.getDICOMSignedLongs(nodePath, instance*)

Returns: String result - the first node that matches the nodePath and instance

Get the result as a \\ delimited string of signed longs of the first node that matches the nodePath.

Note

When the optional instance value is specified, the nodePath should not include an instance identifier.

Parameters

Type	Name	Description	Default
String	nodePath	the DICOM node path
Integer	instance*	(optional) the match instance to return. Use 1 for the first instance.	1

Example

// assumes `message` is a DICOM message model object

// Retrieve signed long values for a DICOM tag
// Returned as a backslash-delimited string
var signedLongs = message.getDICOMSignedLongs(
    "0020,0010"     // Example DICOM tag
);

// Optionally retrieve a specific instance
var signedLongsInstance = message.getDICOMSignedLongs(
    "0020,0010",    // node path
    2               // instance (1 = first instance)
);

// Result:
// - signedLongs contains a string like: "123\\456\\789"
// - signedLongsInstance contains the values for the specified instance
