length

public int length()

Specified by:

length in interface IVector

Specified by:

length in class AVector

isView

public boolean isView()

Description copied from class: AVector

Returns true if this vector is of a view type that references other vectors / data.

Specified by:

isView in interface INDArray

Overrides:

isView in class AVector

Returns:

isFullyMutable

public boolean isFullyMutable()

Description copied from class: AVector

Returns true if this vector is fully mutable, i.e. can contain any unconstrained double values

Specified by:

isFullyMutable in interface INDArray

Overrides:

isFullyMutable in class AVector

Returns:

isMutable

public boolean isMutable()

Description copied from class: AVector

Returns true if this vector is mutable.
