## Class ResultSetMetaDataWrapper

- java.lang.Object
- - groovy.lang.GroovyObjectSupport
  - - groovy.sql.ResultSetMetaDataWrapper

- All Implemented Interfaces:
    GroovyObject

      public class ResultSetMetaDataWrapper
      extends GroovyObjectSupport

  This class defines a wrapper for accessing a specific column in `ResultSetMetaData`. This allows iteration over columns using idiomatic Groovy, e.g.

       meta.each {col ->
         println col.columnName
       }

  All `ResultSetMetaData` column methods taking a column index are available on a column either as a no-arg getter or via a property.

  This wrapper is created by an iterator invoked for `ResultSetMetaData`.
