Introduction
LexEVS CTS2 Association Query Operation API provides capability to query Associations available in the system.
Interface
h2. Introduction LexEVS CTS2 Association Query Operation API provides capability to query Associations available in the system. h2. Interface {{org.lexevs.cts2.query.AssociationQueryOperation}} is the main interface for all the queries against Associations. This interface can be accessed using main LexEVSCTS2 interface: |
...
{code |
}
org.lexevs.cts2.query.AssociationQueryOperation associationQueryOp = new org.lexevs.cts2.LexEvsCTS2Impl().getQueryOperation().getAssociationQueryOperation();

Query Functions
Here are the major query functions available using AssociationQueryOperation interface:
listAssociations
This function returns the resolved concept reference (which contains the associations) according to given node.
listAssociations(String codingSystemName CodingSchemeVersionOrTag versionOrTag String namespace String code String associationName boolean isBackward int depth int maxToReturn)
...
Description:
...
Returns the resolved concept reference (which contains the associations) according to given node.
