Method Detail

newHandler

public static <TConstant extends IConstant,TOperator extends IOperator> IInfixExpressionHandler<TConstant,TOperator> newHandler(ISymbolTable<TConstant,TOperator> symbols)

Parameters:

symbols - A list of symbols supported by the infix expression.

Returns:

A new parser for an infix expression with the given symbols.

newSymbolTable

public static <EOperator extends Enum<EOperator> & IOperator,EConstant extends Enum<EConstant> & IConstant> ISymbolTableBuilder<EConstant,EOperator> newSymbolTable(Class<EOperator> operatorEnum,
                                                                                                                                                                                Class<EConstant> constantEnum)

Parameters:

operatorEnum - Enumeration class with the supported operators.

constantEnum - Enumeration class with the supported symbols.

Returns:

A new symbol table with the given operator and constant symbols.

newSymbolTable

public static <TConstant extends IConstant,TOperator extends IOperator> ISymbolTableBuilder<TConstant,TOperator> newSymbolTable(Iterable<TConstant> constants,
                                                                                                                                            Iterable<TOperator> operators)

Parameters:

operators - A list of supported operators.

constants - A list of supported symbols.

Returns:

A new symbol table with the given operator and constant symbols.
