# IDLffDicomExQuery::Init

The IDLffDicomExQuery::Init function method initializes the IDLffDicomExQuery object. The IDLffDicomExQuery object allows you query or retrieve DICOM files from a remote node configured as a Query SCP available in IDL’s DICOM Network Service configuration. See Using IDL DICOM Network Services for more information.

Note: Init methods are special lifecycle methods, and as such cannot be called outside the context of object creation. This means that in most cases, you cannot call the Init method directly. There is one exception to this rule: if you write your own subclass of this class, you can call the Init method from within the Init method of the subclass.

## Syntax

Obj = OBJ_NEW('IDLffDicomExQuery' )

Result = Obj->[IDLffDicomExQuery::]Init( ) (In a lifecycle method only.)

## Return Value

When this method is called indirectly, as part of the call to the OBJ_NEW function, the return value is an object reference to the newly-created object.

When called directly within a subclass Init method, the return value is one if initialization was successful, or zero otherwise.
