Example 2 with RecordAggregate

use of org.apache.poi.hssf.record.aggregates.RecordAggregate in project poi by apache.

the class InternalSheet method cloneSheet.

/**
     * Clones the low level records of this sheet and returns the new sheet instance.
     * This method is implemented by adding methods for deep cloning to all records that
     * can be added to a sheet. The <b>Record</b> object does not implement cloneable.
     * When adding a new record, implement a public clone method if and only if the record
     * belongs to a sheet.
     * 
     * @return the cloned sheet
     */

    List<Record> clonedRecords = new ArrayList<Record>(_records.size());
