Example 1 with TryStatement

use of de.fraunhofer.aisec.cpg.graph.statements.TryStatement in project cpg by Fraunhofer-AISEC.

the class CXXLanguageFrontendTest method testTryCatch.

@Test

    VariableDeclaration parameter = catchClauses.get(0).getParameter();
    assertNotNull(parameter);
    assertEquals("e", parameter.getName());
    assertEquals(TypeParser.createFrom("const std::exception&", true), parameter.getType());
    // anonymous variable (this is not 100% handled correctly but will do for now)
