RAVectorValues(List<T> vectors,
 int dim)

Method Details

size

public int size()

Description copied from interface: RandomAccessVectorValues

Return the number of vector values

Specified by:

size in interface RandomAccessVectorValues<T>

dimension

public int dimension()

Description copied from interface: RandomAccessVectorValues

Return the dimension of the returned vector values

Specified by:

dimension in interface RandomAccessVectorValues<T>

vectorValue

public T vectorValue(int targetOrd)
              throws IOException

Description copied from interface: RandomAccessVectorValues

Return the vector value indexed at the given ordinal.

Specified by:

vectorValue in interface RandomAccessVectorValues<T>

Parameters:

targetOrd - a valid ordinal, ≥ 0 and < RandomAccessVectorValues.size().

Throws:

IOException

copy

public RandomAccessVectorValues<T> copy()
                                 throws IOException

Description copied from interface: RandomAccessVectorValues

Creates a new copy of this RandomAccessVectorValues. This is helpful when you need to access different values at once, to avoid overwriting the underlying float vector returned by RandomAccessVectorValues.vectorValue(int).

Specified by:

copy in interface RandomAccessVectorValues<T>

Throws:

IOException
