@Operator public final class MutableDenseHashTable extends PrimitiveOp implements Operand<Object>
It uses "open addressing" with quadratic reprobing to resolve collisions.
This op creates a mutable hash table, specifying the type of its keys and values. Each value must be a scalar. Data can be inserted into the table using the insert operations. It does not support the initialization operation.

Operand
Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.
