parseFunction()

std::shared_ptr< ExpressionNode > const & connectivity::FunctionParser::parseFunction ( const OUString &  _sFunction )

static

Parse a string.

The following grammar is accepted by this method:

number_digit = '0'|'1'|'2'|'3'|'4'|'5'|'6'|'7'|'8'|'9'

number = number number_digit | number_digit

equal_function = '=' ternary_function = 'if'

string_reference = 'a-z,A-Z,0-9' ' ' modifier_reference = '$' '0-9' ' '

basic_expression = number | string_reference | additive_expression equal_function additive_expression | unary_function '(' number_digit ')' ternary_function '(' additive_expression ',' additive_expression ', ' additive_expression ')' | '(' additive_expression ')'

Parameters

rFunction

The string to parse

Exceptions

ParseError

if an invalid expression is given.

Returns

the generated function object.
