Examples of TupleBatch

org.teiid.common.buffer.TupleBatch
Represents a set of indexed tuples. The {@link #getBeginRow beginning row}is the first row contained in this batch; if it equals "1" then it is the first row of the tuple source, otherwise this is a batch of intermediate tuples. The {@link #getEndRow ending row} is the last row contained in this tuple batch; it is equal to the beginning row plus the {@link #getRowCount number of rows} contained in this batch, minus one.This object is immutable and Serializable;
