public class BatchingStatementWrapper
extends GroovyObjectSupport
implements java.lang.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.
