Field Detail

tableName

private java.lang.String tableName

This class implements Formatable. That means that it can write itself to and from a formatted stream. If you add more fields to this class, make sure that you also write/read them with the writeExternal()/readExternal() methods. If, inbetween releases, you add more fields to this class, then you should bump the version number emitted by the getTypeFormatId() method.

tableInfo

protected transient TabInfo tableInfo

Constructor Detail

RowList

public RowList()

Public niladic constructor. Needed for Formatable interface to work.

RowList

public RowList(TabInfo tableInfo)

Constructor. Creates a list of rows for a table.

Parameters:

tableInfo - Table information

RowList

public RowList(java.lang.String tableName)

Constructor used for testing.

Parameters:

tableName - name of table that this RowList buffers tuples for.

Method Detail
