Method Detail

convertStringToObject

public static <T> T convertStringToObject(Class<T> type,
                                          String value)
                                   throws InvalidFormatException

Converts string value of the corresponding type to object.

For numeric types (int, long, double, float), this method supports both SI (decimal) and IEC (binary) unit prefixes as postfixes:

• SI prefixes (powers of 1000): k (10³), M (10⁶), G (10⁹), T (10¹²)
• IEC prefixes (powers of 1024): Ki (2¹⁰), Mi (2²⁰), Gi (2³⁰), Ti (2⁴⁰)

Examples:

• "1k" → 1,000
• "1Ki" → 1,024
• "2M" → 2,000,000
• "2Mi" → 2,097,152

The prefixes are case-insensitive. The special value "max" returns the maximum value for numeric types.

Type Parameters:

T - the target type

Parameters:

type - the target type to convert to

value - the string value to convert

Returns:

the converted value

Throws:

InvalidFormatException - if value has wrong format.
