Class SQLStatementRewriterProvider

java.lang.Object
org.compiere.dbPort.SQLStatementRewriterProvider
public class SQLStatementRewriterProvider extends Object
IDEMPIERE-7023 Static helper that aggregates all OSGi-registered ISQLStatementRewriter providers and chains their rewrites. Registered as an immediate OSGi DS component; providers are injected via @Reference (cardinality 0..n, dynamic policy). The static methods delegate to the component instance so callers (Convert, DB_PostgreSQL, DB_Oracle) need no OSGi awareness. Re-entrancy prevention is the responsibility of each ISQLStatementRewriter implementation: providers must not execute SQL through the iDempiere DB layer inside rewriteStatements() — see that method's contract.
