source.getDICOMSignedLongs

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

Signature: source.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

// Example: Retrieve signed long values from a DICOM node.

// Get a backslash-delimited string of signed longs from the first matching node
var signedLongs = source.getDICOMSignedLongs(
    "0020,0010" // DICOM tag
);              // e.g. "1\\0\\-1\\0"

// Get signed longs from a specific instance (useful for sequences)
var signedLongsInstance = source.getDICOMSignedLongs(
    "0020,0010", // DICOM tag
    2            // instance
);
