Constructor Details

CharScannerNumberParserString

public CharScannerNumberParserString(CharScannerRadixHandler radixMode,
 boolean acceptDecimal,
 boolean addRadix)

The constructor.

Parameters:

radixMode - the CharScannerRadixHandler for CharScannerNumberParserBase.radix(int, char).

acceptDecimal - - true to accept decimal numbers (BigDecimal), false otherwise.

addRadix - - true to append the radix syntax to the number String, false otherwise.

CharScannerNumberParserString

public CharScannerNumberParserString(CharScannerRadixHandler radixMode,
 boolean acceptDecimal,
 boolean addRadix,
 String delimiters,
 boolean supportSpecials)

The constructor.

Parameters:

radixMode - the CharScannerRadixHandler for CharScannerNumberParserBase.radix(int, char).

acceptDecimal - - true to accept decimal numbers (BigDecimal), false otherwise.

addRadix - - true to append the radix syntax to the number String, false otherwise.

delimiters - the String with the accepted delimiter characters (e.g. "", "_", or "_,").

supportSpecials - - true to support special numbers like NaN or Infinity.
