Public Methods

Method	Description
CreateResolvedAttributes ( this attributes, ITypeResolveContext context ) : IList
CreateResolvedParameters ( this parameters, ITypeResolveContext context ) : IList
CreateResolvedTypeParameters ( this typeParameters, ITypeResolveContext context ) : IList
FindType ( this compilation, FullTypeName fullTypeName ) : IType	Retrieves the specified type in this compilation. Returns an UnknownType if the type cannot be found in this compilation. There can be multiple types with the same full name in a compilation, as a full type name is only unique per assembly. If there are multiple possible matches, this method will return just one of them. When possible, use IAssembly.GetTypeDefinition instead to retrieve a type from a specific assembly.
GetAllBaseTypeDefinitions ( this type ) : IEnumerable	Gets all base type definitions. The output is ordered so that base types occur before derived types. This is equivalent to type.GetAllBaseTypes().Select(t => t.GetDefinition()).Where(d => d != null).Distinct().
GetAllBaseTypes ( this type ) : IEnumerable	Gets all base types. This is the reflexive and transitive closure of IType.DirectBaseTypes. Note that this method does not return all supertypes - doing so is impossible due to contravariance (and undesirable for covariance as the list could become very large). The output is ordered so that base types occur before derived types.
GetAllTypeDefinitions ( this assembly ) : IEnumerable
GetAllTypeDefinitions ( this file ) : IEnumerable	Gets all unresolved type definitions from the file. For partial classes, each part is returned.
GetAttribute ( this entity, FullTypeName attributeType, bool inherit = true ) : IAttribute	Gets the attribute of the specified attribute type (or derived attribute types).
GetAttribute ( this entity, IType attributeType, bool inherit = true ) : IAttribute	Gets the attribute of the specified attribute type (or derived attribute types).
GetAttributes ( this entity, FullTypeName attributeType, bool inherit = true ) : IEnumerable	Gets the attributes of the specified attribute type (or derived attribute types).
GetAttributes ( this entity, IType attributeType, bool inherit = true ) : IEnumerable	Gets the attributes of the specified attribute type (or derived attribute types).
GetAttributes ( this entity, bool inherit = true ) : IEnumerable	Gets the attribute of the specified attribute type (or derived attribute types).
GetDelegateInvokeMethod ( this type ) : IMethod	Gets the invoke method for a delegate type. Returns null if the type is not a delegate type; or if the invoke method could not be found.
GetInnermostTypeDefinition ( this file, int line, int column ) : IUnresolvedTypeDefinition	Gets the type (potentially a nested type) defined at the specified location. Returns null if no type is defined at that location.
GetMember ( this file, int line, int column ) : IUnresolvedMember	Gets the member defined at the specified location. Returns null if no member is defined at that location.
GetNonInterfaceBaseTypes ( this type ) : IEnumerable	Gets all non-interface base types. When type is an interface, this method will also return base interfaces (return same output as GetAllBaseTypes()). The output is ordered so that base types occur before derived types.
GetSubTypeDefinitions ( this baseType ) : IEnumerable
GetSymbol ( this rr ) : ISymbol
GetTopLevelTypeDefinitons ( this compilation ) : IEnumerable	Gets all top level type definitions in the compilation. This may include types from referenced assemblies that are not accessible in the main assembly.
GetTypeDefinition ( this assembly, FullTypeName fullTypeName ) : ITypeDefinition	Gets the type definition for the specified unresolved type. Returns null if the unresolved type does not belong to this assembly.
GetTypeDefinition ( this assembly, string namespaceName, string name, int typeParameterCount ) : ITypeDefinition	Gets the type definition for a top-level type. This method uses ordinal name comparison, not the compilation's name comparer.
Import ( this compilation, IEntity entity ) : IEntity	Imports an entity from another compilation.
Import ( this compilation, IEvent ev ) : IEvent	Imports a member from another compilation.
Import ( this compilation, IField field ) : IField	Imports a member from another compilation.
Import ( this compilation, IMember member ) : IMember	Imports a member from another compilation.
Import ( this compilation, IMethod method ) : IMethod	Imports a member from another compilation.
Import ( this compilation, INamespace ns ) : INamespace	Imports a namespace from another compilation. This method may return null if the namespace does not exist in the target compilation.
Import ( this compilation, IProperty property ) : IProperty	Imports a member from another compilation.
Import ( this compilation, ISymbol symbol ) : ISymbol	Imports a symbol from another compilation.
Import ( this compilation, IType type ) : IType	Imports a type from another compilation.
Import ( this compilation, ITypeDefinition typeDefinition ) : ITypeDefinition	Imports a type from another compilation.
IsDerivedFrom ( this type, ITypeDefinition baseType ) : bool	Gets whether this type definition is derived from the base type definition.
IsDerivedFrom ( this type, KnownTypeCode baseType ) : bool	Gets whether this type definition is derived from a given known type.
IsKnownType ( this type, KnownTypeCode knownType ) : bool	Gets whether the type is the specified known type. For generic known types, this returns true any parameterization of the type (and also for the definition itself).
IsOpen ( this type ) : bool	Gets whether the type is an open type (contains type parameters).
IsUnbound ( this type ) : bool	Gets whether the type is unbound (is a generic type, but no type arguments were provided). In "`typeof(List<Dictionary<,>>)`", only the Dictionary is unbound, the List is considered bound despite containing an unbound type. This method returns false for partially parameterized types (`Dictionary<string, >`).
Resolve ( this typeReferences, ITypeResolveContext context ) : IList
Resolve ( this constantValues, ITypeResolveContext context ) : IList
Resolve ( this reference, ICompilation compilation ) : IType	Resolves a type reference in the compilation's main type resolve context. Some type references require a more specific type resolve context and will not resolve using this method.

Private Methods
