Method Summary

Modifier and Type	Method and Description
static void	codegenBreakIfNullOrNotPass(CodegenBlock block, java.lang.Class evaluationType, CodegenExpression expression) Generates code like this (premade expr assumed): boolean/Boolean result = expression.evaluate(eps, isNewData, context); if (result == null || (!(Boolean) result)) { break; }

static void	codegenReturnBoolIfNullOrBool(CodegenBlock block, java.lang.Class evaluationType, CodegenExpression expression, boolean earlyExitIfNull, java.lang.Boolean resultEarlyExit, boolean checkFor, boolean resultIfCheckPasses) Generates code like this (premade expr assumed): boolean/Boolean result = expression.evaluate(eps, isNewData, context); if (result == null (optional early exit if null) || (!? (Boolean) result)) { return false/true; }
static void	codegenReturnValueIfNullOrNotPass(CodegenBlock block, java.lang.Class evaluationType, CodegenExpression expression, CodegenExpression value) Generates code like this (premade expr assumed): boolean/Boolean result = expression.evaluate(eps, isNewData, context); if (result == null || (!(Boolean) result)) { return value; }
