nodes - (special rows must be null)

Returns:

root of tree

Throws:

SyntaxNodeException

checkSpecialRows

protected void checkSpecialRows(ColumnMatch columnMatch)
                         throws SyntaxNodeException

Overrides:

checkSpecialRows in class MatchAlgorithmCompiler

Throws:

SyntaxNodeException

getColumnDefinition

Description copied from class: MatchAlgorithmCompiler

Prepares Nodes. Check names, operations and assigns matchers.

Special rows are ignored. That is why first n elements in return array is always null.

Overrides:

prepareNodes in class MatchAlgorithmCompiler

Returns:

array of nodes, elements corresponds rows

Throws:

SyntaxNodeException

Overrides to do nothing.

Overrides:

validateTree in class MatchAlgorithmCompiler

Parameters:

rootNode - root of tree

rows - rows to point out errors
