SodiumPointer<T extends NativeType> class
A C-Pointer wrapper that uses the memory utilities of libsodium.
- Implemented types
- Available Extensions
Constructors
- SodiumPointer.alloc(LibSodiumFFI sodium, {int count = 1, MemoryProtection memoryProtection = MemoryProtection.readWrite, bool zeroMemory = false})
-
Allocates new memory using the libsodium APIs.
factory
-
SodiumPointer.raw(LibSodiumFFI sodium, Pointer<
T> ptr, int count) - Constructs the pointer from the libsodium API, the raw ptr and the element count.
Properties
- byteLength → int
-
The total number of bytes this pointer is long
no setter
- count → int
-
The number of elements this pointer is pointing to
final
- elementSize → int
-
The number of bytes a single element of T is wide.
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- locked ↔ bool
-
Controls whether the pointer is locked in memory or not.
getter/setter pair
- memoryProtection ↔ MemoryProtection
-
Controls the memory protection level of the allocated memory
getter/setter pair
-
ptr
→ Pointer<
T> -
The underlying native C pointer
final
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
asListView<
TNum extends num> () → List< TNum> - Returns a dart list view on the pointer.
-
dispose(
) → void - Disposes the pointer and frees the allocated memory.
-
fill<
TNum extends num> (List< TNum> data, {int offset = 0}) → void - Fills an area of the memory with the given data.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
viewAt(
int offset, [int? length]) → SodiumPointer< T> - Returns a view of a subset of the memory the pointer is pointing to.
-
zeroMemory(
) → void - Provides sodium_memzero
Operators
-
operator ==(
Object other) → bool -
The equality operator.
