@Test
public void rangeOfIntersectionType() {
    String code = "class A {" + EOL + "  Object f() {" + EOL + "    return (Comparator<Map.Entry<K, V>> & Serializable)(c1, c2) -> c1.getKey().compareTo(c2.getKey()); " + EOL + "}}";

    MethodDeclaration methodDeclaration = cu.getClassByName("A").get().getMember(0).asMethodDeclaration();
    ReturnStmt returnStmt = methodDeclaration.getBody().get().getStatement(0).asReturnStmt();
    CastExpr castExpr = returnStmt.getExpression().get().asCastExpr();
    Type type = castExpr.getType();
    assertEquals(range(3, 13, 3, 54), type.getRange().get());

Example 8 with CastExpr

use of com.github.javaparser.ast.expr.CastExpr in project vue-gwt by Axellience.

the class TemplateParser method getTypeFromCast.

/**
 * Get the type of an expression from the cast at the beginning.
 * (int) 12 -> 12 of type int
 * (int) 15 + 5 -> 15 + 5 of type int
 * (float) (12 + 3) -> 12 + 3 of type float
 * ((int) 12) + 3 -> ((int) 12) + 3 of type Any
 * ((JsArray) myArray).getAt(0) -> ((JsArray) myArray).getAt(0) of type Any
 * @param expression The expression to process
 * @return The modified expression (where cast has been removed if necessary)
