DelegatingDatabaseMetaData (Apache Tomcat 10.1.20 API Documentation)
Description: declaration: package: org.apache.tomcat.dbcp.dbcp2, class: DelegatingDatabaseMetaData

Package org.apache.tomcat.dbcp.dbcp2

# Class DelegatingDatabaseMetaData

java.lang.Object
org.apache.tomcat.dbcp.dbcp2.DelegatingDatabaseMetaData

All Implemented Interfaces:
  `DatabaseMetaData`, `Wrapper`

public class DelegatingDatabaseMetaData extends Object implements DatabaseMetaData

A base delegating implementation of `DatabaseMetaData`.

Methods that create `ResultSet` objects are wrapped to create `DelegatingResultSet` objects and the remaining methods simply call the corresponding method on the "delegate" provided in the constructor.

Since:
  2.0
