Introduction

LexEVS CTS2 Code System Query API provides capability to query contents of Code System that are available in the system.

Interface

org.lexevs.cts2.query.CodeSystemQueryOperation is the main interface for all the queries against Code System. This interface can be accessed using main LexEVSCTS2 interface, like:

org.lexevs.cts2.query.CodeSystemQueryOperation csQueryOp = new org.lexevs.cts2.LexEvsCTS2Impl().getQueryOperation().getCodeSystemQueryOperation();

Query Functions

Here are the major query functions available using CodeSystemQueryOperation interface:

listCodeSystems

This function lists the coding systems that are available in cts 2 system. Optionally, return list can be restricted to Code System URI, version, local name, formal name or entity description.

listCodeSystems(CodingSchemeSummary queryByExample)

Description:

List the coding systems that are available in cts 2 system.

Input:

org.LexGrid.LexBIG.DataModel.Core.CodingSchemeSummary queryByExample - (Optional) Restrict the return list only to those that matches the supplied data. return list can be restricted to Code System URI, version, local name, formal name or entity description. If empty, all the code systems available in the system will be returned.

Output:

org.LexGrid.LexBIG.DataModel.Collections.CodingSchemeRenderingList - List of Code Systems

Exception:

org.LexGrid.LexBIG.Exceptions.LBException

Sample Call:

  • Step 1: Instantiate CodeSystemQueryOperation if it is not done yet:
    org.lexevs.cts2.query.CodeSystemQueryOperation csQueryOp = new org.lexevs.cts2.LexEvsCTS2Impl().getQueryOperation().getCodeSystemQueryOperation();
    
  • Step 2a: To get all the code systems:
    org.LexGrid.LexBIG.DataModel.Collections.CodingSchemeRenderingList csrList = csQuery..listCodeSystems(new CodingSchemeSummary());
    
  • Step 2b: To restrict to code system URI:
    CodingSchemeSummary() queryByExample = new CodingSchemeSummary();
