Package groovy.sql

## Class BatchingStatementWrapper

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

- All Implemented Interfaces:
    `GroovyObject`, `AutoCloseable`
  Direct Known Subclasses:
    `BatchingPreparedStatementWrapper`

      public class BatchingStatementWrapper
      extends GroovyObjectSupport
      implements AutoCloseable

  Class which delegates to a Statement but keeps track of a batch count size. If the batch count reaches the predefined number, this Statement does an executeBatch() automatically. If batchSize is zero, then no batching is performed.
