Abstract methods

Parses string to desired type based on provided format.

If parsing fails this function should throw ParseError, possibly wrapping root exception. This is further handled by parse to allow for exception-free, functional code.

Value parameters

fmt: formatter, specific for particular result type, e.g. DateTimeFormatter for dates and times
str: the input string

Attributes

Returns: parsed value
Throws: RuntimeException
if text cannot be parsed to requested type

Inherited methods

Parses string to desired type.

If parsing fails this function should report error by throwing exception. This is further handled by parse to allow for exception-free, functional code.

Value parameters

str: the input string

Attributes

Returns: parsed value
Throws: RuntimeException
if text cannot be parsed to requested type
Note: This function assumes "standard" string formatting, e.g. point as decimal separator or ISO date and time formats, without any locale support. Use FormattedStringParser if more control over source format is required.
