Example 1 with BLangLambdaFunction

use of org.wso2.ballerinalang.compiler.tree.expressions.BLangLambdaFunction in project ballerina by ballerina-lang.

the class TaintAnalyzer method analyzeLambdaExpressions.

private void analyzeLambdaExpressions(BLangInvocation invocationExpr, BLangExpression argExpr) {
    BLangFunction function = ((BLangLambdaFunction) argExpr).function;
    if (function.symbol.taintTable == null) {
        addToBlockedList(invocationExpr);

        int requiredParamCount = function.requiredParams.size();
        int defaultableParamCount = function.defaultableParams.size();
        int totalParamCount = requiredParamCount + defaultableParamCount + (function.restParam == null ? 0 : 1);
        Map<Integer, TaintRecord> taintTable = function.symbol.taintTable;
        for (int paramIndex = 0; paramIndex < totalParamCount; paramIndex++) {
            TaintRecord taintRecord = taintTable.get(paramIndex);
            BLangVariable param = getParam(function, paramIndex, requiredParamCount, defaultableParamCount);
            if (taintRecord == null) {
                addTaintError(argExpr.pos, param.name.value, DiagnosticCode.TAINTED_VALUE_PASSED_TO_SENSITIVE_PARAMETER);
            } else if (taintRecord.taintError != null && taintRecord.taintError.size() > 0) {
                addTaintError(taintRecord.taintError);
            }
            if (stopAnalysis) {
