Examples with TypedNameDeclaration net.sourceforge.pmd.lang.java.symboltable.TypedNameDeclaration used on opensource projects

Example 1 with TypedNameDeclaration

use of net.sourceforge.pmd.lang.java.symboltable.TypedNameDeclaration in project pmd by pmd.

the class InefficientStringBufferingRule method isInStringBufferOperation.

protected static boolean isInStringBufferOperation(Node node, int length, String methodName) {
    if (!(node.getNthParent(length) instanceof ASTStatementExpression)) {
        return false;
    }
    ASTStatementExpression s = node.getFirstParentOfType(ASTStatementExpression.class);
    if (s == null) {
        return false;
    }
    ASTName n = s.getFirstDescendantOfType(ASTName.class);
    if (n == null || n.getImage().indexOf(methodName) == -1 || !(n.getNameDeclaration() instanceof TypedNameDeclaration)) {
        return false;
    }
    // TODO having to hand-code this kind of dredging around is ridiculous
    // we need something to support this in the framework
    // but, "for now" (tm):
    // if more than one arg to append(), skip it
    ASTArgumentList argList = s.getFirstDescendantOfType(ASTArgumentList.class);
    if (argList == null || argList.jjtGetNumChildren() > 1) {
        return false;
    }
    return TypeHelper.isEither((TypedNameDeclaration) n.getNameDeclaration(), StringBuffer.class, StringBuilder.class);
}

Example 2 with TypedNameDeclaration

    }
    if (!TypeHelper.isA((ASTClassOrInterfaceType) node.jjtGetChild(0), String.class)) {

        return data;
    }
    ASTName name = node.getFirstDescendantOfType(ASTName.class);
    // Literal, i.e., new String("foo")
    if (name == null) {
        addViolation(data, node);
        return data;
    }
    NameDeclaration nd = name.getNameDeclaration();

    }
    return data;
}
