Uint32Pointer#

extension Uint32Pointer on Pointer<Uint32>

Extension on Pointer specialized for the type argument Uint32.

Properties#

value extension read / write#

int get value

The 32-bit unsigned integer at address.

A Dart integer is truncated to 32 bits (as if by .toUnsigned(32)) before being stored, and the 32-bit value is zero-extended when it is loaded.

The address must be 4-byte aligned.

Available on Pointer<T extends NativeType>, provided by the Uint32Pointer extension

Implementation

external int get value;

external void set value(int value);

Methods#

asTypedList() extension#

Uint32List asTypedList( int length, { Pointer<NativeFinalizerFunction<Void Function(Pointer<Void> token)>>? finalizer, Pointer<Void>? token, });

Creates a typed list view backed by memory in the address space.

The returned view will allow access to the memory range from address to address + sizeOf<Uint32>() * length.

The user has to ensure the memory range is accessible while using the returned list.

If provided, finalizer will be run on the pointer once the typed list is GCed. If provided, token will be passed to finalizer, otherwise the this pointer itself will be passed.

The address must be 4-byte aligned.

Available on Pointer<T extends NativeType>, provided by the Uint32Pointer extension

Implementation

external Uint32List asTypedList(
  int length, {
  @Since('3.1') Pointer<NativeFinalizerFunction>? finalizer,
  @Since('3.1') Pointer<Void>? token,
});

deprecated elementAt() extension#

Pointer<Uint32> elementAt(int index)

DEPRECATED

Use operator + instead

Pointer arithmetic (takes element size into account).

Available on Pointer<T extends NativeType>, provided by the Uint32Pointer extension

Implementation

@Deprecated('Use operator + instead')
Pointer<Uint32> elementAt(int index) =>
    Pointer.fromAddress(address + sizeOf<Uint32>() * index);

Operators#

operator +() extension#

Pointer<Uint32> operator +(int offset)

A pointer to the offsetth Uint32 after this one.

Returns a pointer to the Uint32 whose address is offset times the size of Uint32 after the address of this pointer. That is (this + offset).address == this.address + offset * sizeOf<Uint32>().

Also (this + offset).value is equivalent to this[offset], and similarly for setting.

Available on Pointer<T extends NativeType>, provided by the Uint32Pointer extension

Implementation

@Since('3.3')
@pragma("vm:prefer-inline")
Pointer<Uint32> operator +(int offset) =>
    Pointer.fromAddress(address + sizeOf<Uint32>() * offset);

operator -() extension#

Pointer<Uint32> operator -(int offset)

A pointer to the offsetth Uint32 before this one.

Equivalent to this + (-offset).

Returns a pointer to the Uint32 whose address is offset times the size of Uint32 before the address of this pointer. That is, (this - offset).address == this.address - offset * sizeOf<Uint32>().

Also, (this - offset).value is equivalent to this[-offset], and similarly for setting,

Available on Pointer<T extends NativeType>, provided by the Uint32Pointer extension

Implementation

@Since('3.3')
@pragma("vm:prefer-inline")
Pointer<Uint32> operator -(int offset) =>
    Pointer.fromAddress(address - sizeOf<Uint32>() * offset);

operator []() extension#

int operator [](int index)

The 32-bit unsigned integer at address + sizeOf<Uint32>() * index.

A Dart integer is truncated to 32 bits (as if by .toUnsigned(32)) before being stored, and the 32-bit value is zero-extended when it is loaded.

The address must be 4-byte aligned.

Available on Pointer<T extends NativeType>, provided by the Uint32Pointer extension

Implementation

external int operator [](int index);

operator []=() extension#

void operator []=(int index, int value)

The 32-bit unsigned integer at address + sizeOf<Uint32>() * index.

A Dart integer is truncated to 32 bits (as if by .toUnsigned(32)) before being stored, and the 32-bit value is zero-extended when it is loaded.

The address must be 4-byte aligned.

Available on Pointer<T extends NativeType>, provided by the Uint32Pointer extension

Implementation

external void operator []=(int index, int value);
