SourceCodeTokenizer(IFunctionNameProvider, INameValueProvider, bool, bool)¶

Constructor

public SourceCodeTokenizer(IFunctionNameProvider functionRepository, INameValueProvider nameValueProvider, bool r1c1 = false, bool keepWhitespace = false)

Parameters¶

functionRepository IFunctionNameProvider

A function name provider

nameValueProvider INameValueProvider

r1c1 bool

If true the tokenizer will use the R1C1 format

keepWhitespace bool

If true whitspaces in formulas will be preserved

Properties¶

Default¶

The default tokenizer. This tokenizer will remove and ignore whitespaces.

public static ISourceCodeTokenizer Default { get; }

R1C1¶

The tokenizer used for r1c1 format. This tokenizer will keep whitespaces and add them as tokens.

public static ISourceCodeTokenizer R1C1 { get; }

Property Value¶

ISourceCodeTokenizer
