->typed-pointer clj

(->typed-pointer item)

Creates a typed-pointer object. Implement PToPtr, mp/PElementCount, and dtype-base/get-datatype and we convert your thing to a typed pointer.

array-copy-fns clj macro

(array-copy-fns)

as-typed-pointer clj

(as-typed-pointer item)

Get something substitutable as a typed-pointer. Implement all the protocols necessary to be tech.datatype.java-unsigned/typed-buffer and PToPtr and you can be considered a typed-pointer, or if you implemented unsigned/typed-buffer? and your backing store is a direct nio buffer (.isDirect returns true)

buffer-as-typed-pointer clj

(buffer-as-typed-pointer item)

Return a typed pointer that shares the backing store with the original direct pointer.

make-jna-pointer clj

(make-jna-pointer address)

Use with care...

make-typed-pointer clj

(make-typed-pointer datatype elem-count-or-seq & [options])

Make a typed pointer. Aside from the usual option :unchecked?, there is a new option :untracked? which means to explicitly avoid using the resource or gc tracking system to track this pointer.

offset-pointer clj

(offset-pointer ptr offset)

pointer->address clj

(pointer->address ptr)

possible-fast-path clj

typed-data-setter clj macro

(typed-data-setter datatype set-fn ptr item-seq)

typed-pointer->ptr clj

(typed-pointer->ptr typed-pointer)

typed-pointer? clj

(typed-pointer? item)

True if you are can be substituted for typed pointers directly.

unsafe-address->typed-pointer clj

(unsafe-address->typed-pointer address byte-len datatype)

unsafe-free-ptr clj

(unsafe-free-ptr ptr)
