Package groovy.sql

Class BatchingStatementWrapper

  • All Implemented Interfaces:
    groovy.lang.GroovyObject, java.lang.AutoCloseable
    Direct Known Subclasses:
    BatchingPreparedStatementWrapper
    public class BatchingStatementWrapper
extends groovy.lang.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.
