Imports
ch.randelshofer.fastdoubleparser.JavaBigDecimalParser, java.math.BigDecimal
Internal Jackson Helper class used to implement more optimized parsing of BigDecimal for REALLY big values (over 500 characters).

This class is not meant to be used directly. It is designed to be used by Jackson JSON parsers (and parsers for other Jackson supported data formats). The parsers check for invalid characters and the length of the number. Without these checks, this parser is susceptible to performing badly with invalid inputs. If you need to parse numbers directly, please use JavaBigDecimalParser in fastdoubleparser instead.

Based on ideas from this this git commit.

2.13

public static BigDecimal parse(String valueStr)

Internal Jackson method. Please do not use.

Note

Caller MUST pre-validate that given String represents a valid representation of BigDecimal value: parsers in jackson-core do that; other code must do the same.

Returns:BigDecimal
