String endpointUrl = URL.getSalesforceBaseUrl().toExternalForm() +
                         + '/services/data/v38.0/tooling/query/? + 
                         + q=Select+Id,Name,SymbolTable,Body+From+ApexClass+where+Id= Apex class salesforce id';

I am able to get following information through above query using tooling api :

    SymbolTable={constructors=(), externalReferences=(), id=01p2800000E0Fc2AAF, innerClasses=(), interfaces=(), key=01p2800000E0Fc2AAF, methods=({annotations=(), location={column=41, line=4}, modifiers=(static, public), name=getItems, parameters=(), references=(), returnType=LIST, type=null}, {annotations=(), location={column=35, line=12}, modifiers=(static, public), name=saveItem, parameters=({name=item, type=Camping_Item__c}), references=(), returnType=Camping_Item__c, type=null}), name=CampingListController, namespace=null, parentClass=, ...},

I want to fetch symbol Table field **methods** explicitly to know the methods in apex class and its parameters. Any idea how to parse the SymbolTable fields?

I have referred following document : [link](https://developer.salesforce.com/docs/atlas.en-us.api_tooling.meta/api_tooling/tooling_api_objects_symboltable.htm#topic-title)
