Constructor Detail
Utility method to easily build a Method
using a more Crystal-style
syntax.
Instance Method Detail
Returns true
if this reference is the same as other. Invokes same?
.
Turns the method name into something canonical to Crystal. If a
explicit #crystal_name
name is set, it'll be returned without furtehr
processing. If override is not nil
, it'll be used over #name
.
Otherwise, the generated name will be based on #name
.
Checks if this method is equal to other, except for the const-qualification.
Checks if this method is equl to other, as is suitable to determine if they're the same for C++ virtual methods between parent- and sub-classes.
Checks if the #crystal_name
was set explicitly (true
), or will be
generated (false
).
Is this method filtered out?
TODO Can we move this into Processor::FilterMethods
?
Returns the index of the first argument with a default value, if any.
Generates a C++ function pointer type matching this methods prototype.
Merges this and the other method with regards to default values and type deductions. Expects that this and other methods point at the same method, but in different classes in the inheritance chain.
Keeps the class name, access, constness, virtuality and type of this method.
The method this method is based on. Used by #variants
to indicate
the methods origin when splitting occurs.
Yields all variants of this method, going through an increasing level of default arguments. It will respect exposed default-values.
A C++ method like int foo(int a, int b = 1, std::string c = "foo")
would yield two methods like:
int foo(int a, int b, std::string c)
int foo(int a, int b = 1)
Note that only built-in types (These are: Integers, Floats and Booleans)
support an exposed default value. For other types (Like std::string
in the example), no default value will be set.
Also see #find_variant_splits
for the algorithm.
