C# Class Pchp.CodeAnalysis.Symbols.PE.MemberRefMetadataDecoder

This subclass of MetadataDecoder is specifically for finding method symbols corresponding to method MemberRefs. The parent implementation is unsuitable because it requires a PEMethodSymbol for context when decoding method type parameters and no such context is available because it is precisely what we are trying to find. Since we know in advance that there will be no context and that signatures decoded with this class will only be used for comparison (when searching through the methods of a known TypeSymbol), we can return indexed type parameters instead.

MemberRefMetadataDecoder ( PEModuleSymbol moduleSymbol, TypeSymbol containingType ) : Microsoft.CodeAnalysis

Protected Methods

Method	Description
GetGenericMethodTypeParamSymbol ( int position ) : TypeSymbol	We know that we'll never have a method context because that's what we're trying to find. Instead, just return an indexed type parameter that will make comparison easier.
GetGenericTypeParamSymbol ( int position ) : TypeSymbol	This override changes two things: 1) Return type arguments instead of type parameters. 2) Handle non-PE types.

Method Details

GetGenericMethodTypeParamSymbol() protected method

We know that we'll never have a method context because that's what we're trying to find. Instead, just return an indexed type parameter that will make comparison easier.

protected GetGenericMethodTypeParamSymbol ( int position ) : TypeSymbol
position	int
return	TypeSymbol

GetGenericTypeParamSymbol() protected method

This override changes two things: 1) Return type arguments instead of type parameters. 2) Handle non-PE types.

protected GetGenericTypeParamSymbol ( int position ) : TypeSymbol
position	int
return	TypeSymbol

MemberRefMetadataDecoder() public method
