    <p>I am trying to extract the class name of a parameter to a method call in objective-C. The code I am parsing is:</p> <pre><code>- (void)testAddConcreteDataModel:(DFDemoDataModelOne*)helpmeh { [self.dataModels addObject:helpmeh]; } </code></pre> <p>And the result I need is the type of class of helpmeh, which is "DFDemoDataModelOne".</p> <p>So far I have the following code, which outputs: <code>"[(DFDataModelContainer).dataModels addObject:helpmeh]"</code></p> <pre><code> if (cursor.kind == CXCursor_ObjCMessageExpr) { __block NSString* memberName = nil; __block NSString* ownerClassName = nil; __block NSString* methodName = [NSString stringWithUTF8String:clang_getCString(clang_getCursorDisplayName(cursor))]; clang_visitChildrenWithBlock(cursor, ^enum CXChildVisitResult(CXCursor cursor, CXCursor parent) { if (cursor.kind == CXCursor_MemberRefExpr) { memberName = [NSString stringWithUTF8String:clang_getCString(clang_getCursorDisplayName(cursor))]; ownerClassName = [NSString stringWithUTF8String:clang_getCString(clang_getCursorDisplayName(clang_getCursorSemanticParent(clang_getCursorReferenced(cursor))))]; } else { if (memberName) { NSString* param = [NSString stringWithUTF8String:clang_getCString(clang_getCursorDisplayName(cursor))]; NSLog(@"[(%@).%@ %@%@]", ownerClassName, memberName, methodName, param); clang_visitChildrenWithBlock(cursor, ^enum CXChildVisitResult(CXCursor cursor, CXCursor parent) { // test if ([param isEqualToString:@"helpmeh"] &amp;&amp; cursor.kind == CXCursor_DeclRefExpr) { // found the interesting part.. what now? } return CXChildVisit_Recurse; } } } return CXChildVisit_Continue; } } </code></pre> <p>I'm just a bit lost as to how to extract information from cursors- when I AST dump my class I can see the information I need is all there (see the last line):</p> <pre><code>|-ObjCMethodDecl 0x112790f90 &lt;line:32:1, line:34:1&gt; - testAddConcreteDataModel: 'void' | |-ImplicitParamDecl 0x112791960 &lt;&lt;invalid sloc&gt;&gt; self 'DFDataModelContainer *const __strong' | |-ImplicitParamDecl 0x1127919c0 &lt;&lt;invalid sloc&gt;&gt; _cmd 'SEL':'SEL *' | |-ParmVarDecl 0x112791040 &lt;line:32:35, col:55&gt; helpmeh 'DFDemoDataModelOne *__strong' | `-CompoundStmt 0x112791bf0 &lt;col:63, line:34:1&gt; | `-ExprWithCleanups 0x112791bd8 &lt;line:33:5, col:39&gt; 'void' | `-ObjCMessageExpr 0x112791ba0 &lt;col:5, col:39&gt; 'void' selector=addObject: | |-PseudoObjectExpr 0x112791b48 &lt;col:6, col:11&gt; 'NSMutableArray *' | | |-ObjCPropertyRefExpr 0x112791ad0 &lt;col:6, col:11&gt; '&lt;pseudo-object type&gt;' lvalue objcproperty Kind=PropertyRef Property="dataModels" Messaging=Getter | | | `-OpaqueValueExpr 0x112791ab0 &lt;col:6&gt; 'DFDataModelContainer *' | | | `-ImplicitCastExpr 0x112791a40 &lt;col:6&gt; 'DFDataModelContainer *' &lt;LValueToRValue&gt; | | | `-DeclRefExpr 0x112791a18 &lt;col:6&gt; 'DFDataModelContainer *const __strong' lvalue ImplicitParam 0x112791960 'self' 'DFDataModelContainer *const __strong' | | |-OpaqueValueExpr 0x112791ab0 &lt;col:6&gt; 'DFDataModelContainer *' | | | `-ImplicitCastExpr 0x112791a40 &lt;col:6&gt; 'DFDataModelContainer *' &lt;LValueToRValue&gt; | | | `-DeclRefExpr 0x112791a18 &lt;col:6&gt; 'DFDataModelContainer *const __strong' lvalue ImplicitParam 0x112791960 'self' 'DFDataModelContainer *const __strong' | | `-ImplicitCastExpr 0x112791b30 &lt;col:11&gt; 'NSMutableArray *' &lt;ARCReclaimReturnedObject&gt; | | `-ObjCMessageExpr 0x112791b00 &lt;col:11&gt; 'NSMutableArray *' selector=dataModels | | `-OpaqueValueExpr 0x112791ab0 &lt;col:6&gt; 'DFDataModelContainer *' | | `-ImplicitCastExpr 0x112791a40 &lt;col:6&gt; 'DFDataModelContainer *' &lt;LValueToRValue&gt; | | `-DeclRefExpr 0x112791a18 &lt;col:6&gt; 'DFDataModelContainer *const __strong' lvalue ImplicitParam 0x112791960 'self' 'DFDataModelContainer *const __strong' | `-ImplicitCastExpr 0x112791b88 &lt;col:32&gt; 'id':'id' &lt;BitCast&gt; | `-ImplicitCastExpr 0x112791b70 &lt;col:32&gt; 'DFDemoDataModelOne *' &lt;LValueToRValue&gt; | `-DeclRefExpr 0x112791a88 &lt;col:32&gt; 'DFDemoDataModelOne *__strong' lvalue ParmVar 0x112791040 'helpmeh' 'DFDemoDataModelOne *__strong' </code></pre> <p>Any pointers greatly appreciated!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
