Method Detail

getCandidateMethods

public static List<FacebookMethodsType> getCandidateMethods(String name,
                                                            String... argNames)

Gets methods that match the given name and arguments.

Note that the args list is a required subset of arguments for returned methods.

Parameters:

name - case sensitive full method name to lookup

argNames - unordered required argument names

Returns:

non-null unmodifiable list of methods that take all of the given arguments, empty if there is no match

filterMethods

public static List<FacebookMethodsType> filterMethods(List<FacebookMethodsType> methods,
                                                      FacebookMethodsTypeHelper.MatchType matchType,
                                                      String... argNames)

Filters a list of methods to those that take the given set of arguments.

Parameters:

methods - list of methods to filter

matchType - whether the arguments are an exact match, a subset or a super set of method args

argNames - argument names to filter the list

Returns:

methods with arguments that satisfy the match type.

For SUPER_SET match, if methods with exact match are found, methods that take a subset are ignored

getArguments

public static List<Object> getArguments(String name)
                                 throws IllegalArgumentException

Gets argument types and names for all overloaded methods with the given name.

Parameters:

name - method name, must be a long form (i.e. get*, or search*)

Returns:

list of arguments of the form Class type1, String name1, Class type2, String name2,...

Throws:

IllegalArgumentException

getArgumentsForNameStyle

public static List<Object> getArgumentsForNameStyle(String name,
                                                    FacebookNameStyle style)
                                             throws IllegalArgumentException

Gets argument types and names for all overloaded methods with the given short form name.

Parameters:

name - method name, may be a short form

style - name style

Returns:

list of arguments of the form Class type1, String name1, Class type2, String name2,...

Throws:

IllegalArgumentException

getMissingProperties

public static Set<String> getMissingProperties(String methodName,
                                               FacebookNameStyle nameStyle,

Get the type for the given argument name.

Parameters:

argName - argument name

Returns:

argument type
