UNLESS_MERGELIBS (SVXCORE_DLLPUBLIC) static std EnhancedCustomShape::FunctionParser::FunctionParser ( )
delete

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

identifier = 'pi'|'left'|'top'|'right'|'bottom'|'xstretch'|'ystretch'| 'hasstroke'|'hasfill'|'width'|'height'|'logwidth'|'logheight'

unary_function = 'abs'|'sqrt'|'sin'|'cos'|'tan'|'atan' binary_function = 'min'|'max'|'atan2' ternary_function = 'if'

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

basic_expression = number | identifier | function_reference | unary_function '(' additive_expression ')' | binary_function '(' additive_expression ',' additive_expression ')' | ternary_function '(' additive_expression ',' additive_expression ', ' additive_expression ')' | '(' additive_expression ')'

unary_expression = '-' basic_expression

multiplicative_expression = basic_expression | multiplicative_expression '*' basic_expression | multiplicative_expression '/' basic_expression

additive_expression = multiplicative_expression | additive_expression '+' multiplicative_expression | additive_expression '-' multiplicative_expression

Parameters
rFunctionThe string to parse
rCustoShapeThe CustomShape is required for calculation of dynamic values such "hasstroke", function references and or modifier references ...
Exceptions
ParseErrorif an invalid expression is given.
Returns
the generated function object.
