Class DelegatingDatabaseMetaData

java.lang.Object
  org.apache.commons.dbcp.AbandonedTrace
      org.apache.commons.dbcp.DelegatingDatabaseMetaData

All Implemented Interfaces:: DatabaseMetaData, Wrapper

public class DelegatingDatabaseMetaData
extends AbandonedTrace
implements DatabaseMetaData
extends AbandonedTrace
implements DatabaseMetaData

A base delegating implementation of DatabaseMetaData.

Those 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 my constructor.

Extends AbandonedTrace to implement DatabaseMetaData tracking and logging of code which created the DatabaseMetaData. Tracking the DatabaseMetaData ensures that the Connection which created it can close any associated ResultSets on Connection close.

Field Summary
`protected DelegatingConnection`	`_conn` The connection that created me.
`protected DatabaseMetaData`	`_meta` My delegate `DatabaseMetaData`
