No instances are allowed to be constructed from this class.

Member Function Documentation

FloatingPoint()

static std::pair<std::string,std::regex> FloatingPoint ( )

static

Get a string-regex pair representing an integer.

Matches the following pattern:

• optional leading '-'
• whole part identical to RegexUtility::Integer
• optional decimal point, optionally followed by the fractional part [0-9]*
• optional scientific notation suffix [eE][+-][0-9]+

Returns

A pair of

• std::string of a regex pattern representing a floating point number in decimal or scientific notation.
• std::regex of that string.

Note

This function can be called safely from other static functions.

Integer()

static std::pair<std::string,std::regex> Integer ( )

static

Get a string-regex pair representing an integer.

Matches the following pattern:

• optional leading '-'
• 0 or [1-9]+[0-9]*

Returns

A pair of

• std::string of a regex pattern representing an integer.
• std::regex of that string.

Note

This function can be called safely from other static functions.

UnsignedInteger()

static std::pair<std::string,std::regex> UnsignedInteger ( )

static

Get a string-regex pair representing an unsigned integer.

Matches the following pattern:

• 0 or [1-9]+[0-9]*

Returns

A pair of

• std::string of a regex pattern representing an unsigned integer.
• std::regex of that string.

Note

This function can be called safely from other static functions.
