SharedPointer<T> class abstract

Base class for a dart:ffi Pointer that can be shared between Isolates.

To share this points just send to the other Isolate the SharedPointer.address. Then in the other Isolate side just call SharedPointerAddress.getPointer, to have the working SharedPointer instance.

Note that a ffi.Pointer originally can't shared between Isolates, but sharing the pointer address allows the same memory are to be acessed simultaneously by different Isolate. For now there's no mutex implementation to allow control of the owner thread of the SharedPointer.

Properties

address ↔ SharedPointerAddress
latefinal
endian → Endian
The endianness of this pointer.
no setter
hashCode → int
The hash code for this object.
no setterinherited
isClosed → bool
Returns true if this instance is closed (in the current Isolate).
no setter
isInitializer → bool
Returns true if this instance is the initializer instance, that actually allocated the pointer. Only the initializer instance can free the pointer.
no setter
requiresSerializationToBeShared → bool
Forces serialization and deserialization even when SharedData.noSerializationOnDartNative is true.
no setteroverride
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

checkClosed() → void
Checks if the instance is NOT closed, or throws a StateError.
computeSignature() → String
Computes the signature of this instance.
override
copy() → SerializableData<SharedPointer<T>, SharedPointerAddress>
Creates a copy of this instance.
inherited
deserialize(SharedPointerAddress serial) → SerializableData<SharedPointer<T>, SharedPointerAddress>
Deserializes serial to a instance of this type.
inherited
deserializeData(SharedPointerAddress serial) → SharedPointer<T>
Deserializes serial to D.
inherited
free() → void
Closes this instance and calls malloc.free for the Pointer if this is the initializer instance. See isInitializer.
instantiate(SharedPointer<T> data) → SerializableData<SharedPointer<T>, SharedPointerAddress>
Creates a new instance with data.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
read() → T?
Reads a value from the Pointer memory.
readNewValue({T? lastValue, Duration? interval, Duration? timeout, bool acceptsNullValue = true}) → FutureOr<T?>
Reads a new value, different from lastValue, performing a pooling with interval (default: 10ms) and a timeout (default: 10s) that checks for a new value if needed.
serialize() → SharedPointerAddress
Serializes this instance to S.
override
toString() → String
A string representation of this object.
inherited
write(T value) → void
Writes a value to the Pointer memory.

Operators

operator ==(Object other) → bool
The equality operator.
