Public Methods

Method	Description
CanBeOverride ( SourceMethodSymbol method, MethodSymbol basemethod ) : bool	Determines whether method can override basemethod.
OverrideCost ( SourceMethodSymbol method, MethodSymbol basemethod ) : ConversionCost	Calculates override cost, i.e. whether the override is possible and its value. In case of more possible overrides, the one with better cost is selected.
ResolveOverride ( this method ) : MethodSymbol	Resolves best method to be overriden.
SignaturesMatch ( this a, MethodSymbol b ) : bool	Checks whether signatures of two methods match exactly so one can override the second.

Private Methods

Method	Description
EnumerateOverridableTypes ( NamedTypeSymbol type ) : IEnumerable	Enumerates base types and interfaces of given type (i.e. types that can contain methods that can be overriden).
IsAllowedCost ( ConversionCost cost ) : bool

Method Details

CanBeOverride() public static method

Determines whether method can override basemethod.

public static CanBeOverride ( SourceMethodSymbol method, MethodSymbol basemethod ) : bool
method	SourceMethodSymbol	Source method.
basemethod	MethodSymbol	Overriden method.
return	bool

OverrideCost() public static method

Calculates override cost, i.e. whether the override is possible and its value. In case of more possible overrides, the one with better cost is selected.

public static OverrideCost ( SourceMethodSymbol method, MethodSymbol basemethod ) : ConversionCost
method	SourceMethodSymbol	Source method.
basemethod	MethodSymbol	A hypothetical base method.
return	ConversionCost

ResolveOverride() public static method

Resolves best method to be overriden.

public static ResolveOverride ( this method ) : MethodSymbol
method	this	The override.
return	MethodSymbol

SignaturesMatch() public static method

Checks whether signatures of two methods match exactly so one can override the second.

public static SignaturesMatch ( this a, MethodSymbol b ) : bool
a	this
b	MethodSymbol
