Methods
-
dispose(
) → void -
Releases the underlying native resources. Idempotent: calling it more
than once is safe, but the object must not be used after dispose.
inherited
-
freeNative(
) → void -
Frees the native resources owned by this object. Subclasses implement the
concrete free logic here; callers must use dispose instead.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
pow(
int n) → Scalar -
sqrt(
) → Scalar -
toString(
) → String -
A string representation of this object.

Operators
-
operator *(
Scalar other) → Scalar -
operator +(
Scalar other) → Scalar -
operator -(
Scalar other) → Scalar -
operator /(
Scalar other) → Scalar -
operator ==(
Object other) → bool -
The equality operator.
