Class ST_Concat

java.lang.Object

fr.mines_stetienne.ci.sparql_generate.function.library.ST_Concat

All Implemented Interfaces:

org.apache.jena.sparql.function.Function

public class ST_Concat
extends Object
implements org.apache.jena.sparql.function.Function

Function st:concat concatenates the string values of its arguments, as in STTL. The template expressions of a TEMPLATE query are compiled to a call to st:concat.

The arguments are evaluated in turn and written to a template output of their own, so that the indentation set by st:incr and st:decr, the functions that BOX uses, applies to them. An argument that cannot be evaluated is skipped; with the option debugTemplate, an error message is written in its place.
