Detailed Description

Generate code for a parsed expression.

Almost all code generation is dedicated to the gd::EventsCodeGenerator, so that it can be adapted to the target.

◆ GenerateExpressionCode()

gd::String gd::ExpressionCodeGenerator::GenerateExpressionCode ( EventsCodeGenerator &  codeGenerator,
EventsCodeGenerationContext &  context,
const gd::String &  type,
const gd::Expression &  expression,
const gd::String &  objectName = "",
const gd::String &  extraInfo = "" 
)
static

Helper to generate the code for an expression. If expression is invalid, a default generated value is returned (0 for number expression, empty string for strings).

Parameters
codeGeneratorThe code generator to use to output code.
contextThe context of the code generation.
typeThe type of the expression (see gd::ExpressionParser2).
expressionThe expression to parse and generate code for.
objectThe object the expression refers too (only for "objectvar" type).
