Class MethodHierarchyReader

java.lang.Object

com.google.api.server.spi.MethodHierarchyReader

public class MethodHierarchyReader
extends Object

Utility to take a class and create maps of methods usable for endpoints and related data.

On the first call, parses and stores the full hierarchy information. The cached full hierarchy is then used for all subsequent calls. Returned iterables, maps, and lists are copied out without reference to the original full hierarchy information to allow the caller to keep just the needed portion of information and release the full hierarchy along with this class.

MethodHierarchyReader

public MethodHierarchyReader(Class<?> endpointClass)

Constructs a MethodHierarchyReader for the given class type.

Parameters:

endpointClass - Must be a concrete type (not abstract or interface).

Method Detail

getLeafMethods

public Iterable<Method> getLeafMethods()

Returns a collection of public service methods defined by the class and its super classes. Bridge methods are ignored. Only the final leaf subclass version of each method is included.

getLeafEndpointMethods

public Iterable<EndpointMethod> getLeafEndpointMethods()

Returns a collection of public service methods defined by the class and its super classes. Bridge methods are ignored. Only the final leaf subclass version of each method is included. Methods are stored in the EndpointMethod container.

getMethodOverrides

public Iterable<List<Method>> getMethodOverrides()

Returns a collection of public service methods defined by the class and its super classes. Bridge methods are ignored. For each method, all valid method implementations are included, ordered subclass to superclass.

getEndpointOverrides

public Iterable<List<EndpointMethod>> getEndpointOverrides()

Returns a collection of public service methods defined by the class and its super classes. Bridge methods are ignored. For each method, all valid method implementations are included, ordered subclass to superclass. Methods are stored in the EndpointMethod container.

getNameToLeafMethodMap

public Map<String,Method> getNameToLeafMethodMap()

Returns a mapping of public service methods defined by the class and its super classes, keyed by method name. Bridge methods are ignored. Only the final leaf subclass version of each method is included.

getNameToEndpointOverridesMap

public com.google.common.collect.ListMultimap<String,EndpointMethod> getNameToEndpointOverridesMap()

Returns a mapping of public service methods defined by the class and its super classes, keyed by method name. Bridge methods are ignored. All valid method implementations are included, ordered subclass to superclass.
