Creates an empty hash table that uses tensors as the backing store.
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.

Inherited Methods
Public Methods
public Output<Object> asOutput ()
Returns the symbolic handle of a tensor.
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.
public static MutableDenseHashTable.Options container (String container)
Parameters
container | If non-empty, this table is placed in the given container. Otherwise, a default container is used. |
---|
public static MutableDenseHashTable create (Scope scope, Operand<T> emptyKey, Operand<T> deletedKey, Class<U> valueDtype, Options... options)
Factory method to create a class wrapping a new MutableDenseHashTable operation.
Parameters
scope | current scope |
---|---|
emptyKey | The key used to represent empty key buckets internally. Must not be used in insert or lookup operations. |
valueDtype | Type of the table values. |
options | carries optional attributes values |
Returns
- a new instance of MutableDenseHashTable
public static MutableDenseHashTable.Options initialNumBuckets (Long initialNumBuckets)
Parameters
initialNumBuckets | The initial number of hash table buckets. Must be a power to 2. |
---|
public static MutableDenseHashTable.Options maxLoadFactor (Float maxLoadFactor)
Parameters
maxLoadFactor | The maximum ratio between number of entries and number of buckets before growing the table. Must be between 0 and 1. |
---|
public static MutableDenseHashTable.Options sharedName (String sharedName)
Parameters
sharedName | If non-empty, this table is shared under the given name across multiple sessions. |
---|
public static MutableDenseHashTable.Options valueShape (Shape valueShape)
Parameters
valueShape | The shape of each value. |
