Detailed Description

Class to parse parameters from string.

Member functions prefixed with parse_ have a int argument at last. This flag is to indicate whether parsing is succesful. The meaning of return value:

• 0: succesful
• 1: failed to find the parameter string, or the parameter value is empty
• 2: find the parameter string, but fail to convert the value to requested type

When multiple matches are found, the last one will be used.

Only successful parse will lead to value change of the variable. Otherwise the default value will be used.
