Methods
-
clone(
) → SparseVector -
Available on SparseVector, provided by the CloneSparseVector extension
Creates a deep copy of the SparseVector, mutations to the original will not affect the copy. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toBinary(
) → Uint8List - Converts the sparse vector to its binary representation.
-
toJson(
) → String -
Available on SparseVector, provided by the SparseVectorJsonExtension extension
Returns a serialized version of the SparseVector as a String. -
toList(
) → List< double> - Returns the sparse vector as a dense list of double values.
-
toString(
) → String -
A string representation of this object.
