Annotation Type FFIFunGen

public @interface FFIFunGen

Used to match a method in a given class. The signature of a method is computed as the combination of the name, the types of the parameters and the type of the return value. The type of a parameter of a return value must be a type that is supported by fastFFI, i.e., a Java boxed or unboxed primitive type, a type variable, and a FFIType and its parameterized type (e.g., CXXEnum or FFIPointer). If the type is a generic type, e.g., (StdVector<String>), the configured type name must be the raw type (apply type erasure to the type), e.g., StdVector. For example, the following method has included all possible types, and the canonical full name of each type.

 import std.StdVector;
 import std.StdString;
 class Foo {
     StdVector<Integer> <T> get(T t, StdString str, StdVector<StdVector<Long>> in, int a, Float f);
 }
 

And we can use the following annotation to match the method
