Method Detail

assignExecutor

protected void assignExecutor(ColumnMatch columnMatch)

buildTree

protected MatchNode buildTree(List<TableRow> rows,
                              MatchNode[] nodes)
                       throws SyntaxNodeException

Builds tree based on indentation of each row.

Parameters:

nodes - (special rows must be null)

Returns:

root of tree

Throws:

SyntaxNodeException

checkRowName

protected void checkRowName(TableRow row,
                            String expectedName)
                     throws SyntaxNodeException

Throws:

SyntaxNodeException

checkSpecialRows

protected void checkSpecialRows(ColumnMatch columnMatch)
                         throws SyntaxNodeException

Throws:

SyntaxNodeException

compile

public void compile(IBindingContext bindingContext,
                    ColumnMatch columnMatch)
             throws SyntaxNodeException

Specified by:

compile in interface IMatchAlgorithmCompiler

Throws:

SyntaxNodeException

getColumnDefinition

protected List<ColumnDefinition> getColumnDefinition()

getSpecialRowCount

protected int getSpecialRowCount()

parseCheckValues

protected void parseCheckValues(IBindingContext bindingContext,
                                ColumnMatch columnMatch,
                                TableRow row,
                                MatchNode node,
                                int retValuesCount)

Parses CheckValues for node(row). It is up to matcher (type of variable in 'names') how to parse it.

parseSpecialRows

protected void parseSpecialRows(IBindingContext bindingContext,
                                ColumnMatch columnMatch)
                         throws SyntaxNodeException

Compiles (parses) return values based on return type.

Throws:

SyntaxNodeException

parseValues

protected Object[] parseValues(IBindingContext bindingContext,
                               ColumnMatch columnMatch,
                               TableRow row,
                               IOpenClass openClass)
                        throws SyntaxNodeException

Throws:

SyntaxNodeException

setMetaInfoForConstant

protected void setMetaInfoForConstant(IBindingContext bindingContext,
                                      ColumnMatch columnMatch,
                                      SubValue sv,
                                      ConstantOpenField constantOpenField)

prepareNodes

protected MatchNode[] prepareNodes(IBindingContext bindingContext,
                                   ColumnMatch columnMatch,
                                   ArgumentsHelper argumentsHelper,
                                   int retValuesCount)
                            throws SyntaxNodeException

Prepares Nodes. Check names, operations and assigns matchers.

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

Returns:

array of nodes, elements corresponds rows

Throws:

SyntaxNodeException

validateTree

protected void validateTree(MatchNode rootNode,
                            List<TableRow> rows,
                            MatchNode[] nodes)
                     throws SyntaxNodeException

Checks that tree is consistent.

Parameters:

rootNode - root of tree

rows - rows to point out errors

Throws:

SyntaxNodeException
