Package com.yahoo.tensor

Class TensorAddress

java.lang.Object

com.yahoo.tensor.TensorAddress

All Implemented Interfaces:

java.lang.Comparable<TensorAddress>

public abstract class TensorAddress
extends java.lang.Object
implements java.lang.Comparable<TensorAddress>

An immutable address to a tensor cell. This simply supplies a value to each dimension in a particular tensor type. By itself it is just a list of cell labels, it's meaning depends on its accompanying type.

Method Detail

of

public static TensorAddress of(java.lang.String[] labels)

ofLabels

public static TensorAddress ofLabels(java.lang.String... labels)

of

public static TensorAddress of(long... labels)

size

public abstract int size()

Returns the number of labels in this

label

public abstract java.lang.String label(int i)

Returns the i'th label in this

Throws:

java.lang.IllegalArgumentException - if there is no label at this index

numericLabel

public abstract long numericLabel(int i)

Returns the i'th label in this as a long. Prefer this if you know that this is a numeric address, but not otherwise.

Throws:

java.lang.IllegalArgumentException - if there is no label at this index

withLabel

public abstract TensorAddress withLabel(int labelIndex,
                                        long label)

isEmpty

public final boolean isEmpty()

compareTo

public int compareTo(TensorAddress other)

Specified by:

compareTo in interface java.lang.Comparable<TensorAddress>

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

toString

public final java.lang.String toString(TensorType type)

Returns this as a string on the appropriate form given the type

labelToString

public static java.lang.String labelToString(java.lang.String label)

Returns a label as a string with approriate quoting/escaping when necessary
