Methods
Clone()
public AstType Clone()Returns
Create(string)
Creates a simple AstType from a dotted name. Does not support generics, arrays, etc. - just simple dotted names, e.g. namespace names.
public static AstType Create(string dottedName)Parameters
dottedNamestring
Returns
GetNameLookupMode()
Gets the name lookup mode from the context (looking at the ancestors of this AstType).
public NameLookupMode GetNameLookupMode()Returns
IsVar()
Gets whether this type is a SimpleType "var".
public bool IsVar()Returns
MakeArrayType(int)
Creates an array type from this type by nesting it in a ComposedType.
If this type already is an array type, the additional rank is prepended to the existing array specifier list.
Thus, new SimpleType("T").MakeArrayType(1).MakeArrayType(2) will result in "T[,][]".
public virtual AstType MakeArrayType(int rank = 1)Parameters
rankint
Returns
MakeNullableType()
Creates a nullable type from this type by nesting it in a ComposedType.
public AstType MakeNullableType()Returns
MakePointerType()
Creates a pointer type from this type by nesting it in a ComposedType. If this type already is a pointer type, this method just increases the PointerRank of the existing pointer type.
public virtual AstType MakePointerType()Returns
MakeRefType()
Creates a C# 7 ref type from this type by nesting it in a ComposedType.
public virtual AstType MakeRefType()Returns
MemberType(string, params AstType[])
Builds an expression that can be used to access a static member on this type.
public MemberType MemberType(string memberName, params AstType[] typeArguments)Parameters
Returns
MemberType(string, IEnumerable<AstType>)
Builds an expression that can be used to access a static member on this type.
public MemberType MemberType(string memberName, IEnumerable<AstType> typeArguments)Parameters
memberNamestringtypeArgumentsIEnumerable<AstType>
Returns
ToTypeReference(NameLookupMode, InterningProvider)
Create an ITypeReference for this AstType.
public abstract ITypeReference ToTypeReference(NameLookupMode lookupMode, InterningProvider interningProvider = null)Parameters
lookupModeNameLookupModeinterningProviderInterningProvider
Returns
Remarks
The resulting type reference will read the context information from the ITypeResolveContext: For resolving type parameters, the CurrentTypeDefinition/CurrentMember is used. For resolving simple names, the current namespace and usings from the CurrentUsingScope (on CSharpTypeResolveContext only) is used.
ToTypeReference(InterningProvider)
Create an ITypeReference for this AstType. Uses the context (ancestors of this node) to determine the correct NameLookupMode.
public ITypeReference ToTypeReference(InterningProvider interningProvider = null)Parameters
interningProviderInterningProvider
Returns
Remarks
The resulting type reference will read the context information from the ITypeResolveContext: For resolving type parameters, the CurrentTypeDefinition/CurrentMember is used. For resolving simple names, the current namespace and usings from the CurrentUsingScope (on CSharpTypeResolveContext only) is used.
