getTableStatistics( $changesMap ) -> \$statistics

Creates a 'statistics' hash that shows the result of applying changes to the EditTableData object:

• {rowCount} : the total number of rows, including header and footer rows
• {added} : the added rows
• {deleted} : the deleted rows
• {bodyRowCount} : the number of body rows

StaticMethod _mergeHashes (\%a, \%b ) -> \%merged

Merges 2 hash references.

StaticMethod createTableChangesMap( $paramString ) -> \%map

Parses the paramString to a hash. paramString can contain a list of key-value pairs using the structure (rowNumber_1=rowState_1,rowNumber_2=rowState_2,...), for example:

1. =0,1=0,2=1

Row states are:

-1

row deleted

0

nothing changed

1

row added

2

reset (no action)

Not all rows have to be present in the param.

StaticMethod tableChangesMapToParamString( \%tableChanges ) -> $paramString

In the reverse operation to createTableChangesMap, converts a tableChanges hash to a param string.

For example, { '0' => '0', '3' => '1' } will be converted to: '0=0,3=1'

StaticMethod _getTableChangeStatistics
