Method Detail

getTypes

public Representable[] getTypes()

Specified by:

getTypes in interface TensorData

Returns:

the types of all dimensions and the value as a single array.

estimatedCardinality

public int estimatedCardinality()

Specified by:

estimatedCardinality in interface TensorData

Returns:

conservative estimate of number of entries in the mapping from dimensions to values. Can be cheaper to evaluate than the exact one.

cardinality

public int cardinality()

Specified by:

cardinality in interface TensorData

Returns:

exact number of entries in the mapping from dimensions to values.

iterator

public TensorIterator iterator()

Specified by:

iterator in interface TensorData

Returns:

an iterator over entries in the mapping from dimensions to the value.

getShape

public long[] getShape()

Specified by:

getShape in interface TensorData

Returns:

the current shape of the data or the supplied shape of the data

getInner

public TensorData getInner()
