                                      int col)

Description copied from interface: MetaInfoReader

Get meta info for a given row and column.

Specified by:

getMetaInfo in interface MetaInfoReader

Parameters:

row - row

col - column

Returns:

meta info

prepare

public void prepare(IGridRegion region)

Description copied from interface: MetaInfoReader

Preliminary load meta info for a given region. For a big tables it's a part of the table, meta info for full table not needed in this case. If this method wasn't invoked before MetaInfoReader.getMetaInfo(int, int), then meta info for full table can be loaded.

Specified by:

prepare in interface MetaInfoReader

Parameters:

region - region to load meta info

release

public void release()

Description copied from interface: MetaInfoReader

Release meta info loaded in MetaInfoReader.prepare(IGridRegion)

Specified by:

release in interface MetaInfoReader

getTableSyntaxNode

protected abstract TableSyntaxNode getTableSyntaxNode()

getHeaderMetaInfo

protected abstract CellMetaInfo getHeaderMetaInfo()

getBodyMetaInfo
