MutableDenseHashTable

public final class MutableDenseHashTable

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.

Constants

public static final String OP_NAME

The name of this op, as known by TensorFlow core engine

Constant Value: "MutableDenseHashTableV2"

Public Methods

public Output<TType> asOutput ()

Returns the symbolic handle of the 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 Output<?> tableHandle ()

Handle to a table.

public static MutableDenseHashTable.Options useNodeNameSharing (Boolean useNodeNameSharing)

public static MutableDenseHashTable.Options valueShape (Shape valueShape)

Parameters

valueShape	The shape of each value.
