Package boofcv.struct.feature

Class PackedTupleArray_B

java.lang.Object

boofcv.struct.feature.PackedTupleArray_B

All Implemented Interfaces:

PackedTupleArray<TupleDesc_B>, PackedArray<TupleDesc_B>, LArrayAccessor<TupleDesc_B>

public class PackedTupleArray_B
extends Object
implements PackedTupleArray<TupleDesc_B>

Stores a set of tuples in a single continuous array. This is intended to make storage of a large number of tuples more memory efficient by removing all the packaging that Java adds to a class. The memory is also continuous, opening the possibility of further optimizations.

Description copied from interface: PackedArray

Resets the array's size to be zero

Specified by:

reset in interface PackedArray<TupleDesc_B>

reserve

public void reserve(int numTuples)

Description copied from interface: PackedArray

Ensure there is enough space to store 'numElements' before the internal array needs to grow. Does not change the size

Specified by:

reserve in interface PackedArray<TupleDesc_B>

Parameters:

numTuples - Minimum number of elements allocated to the array

append

public void append(TupleDesc_B element)

Description copied from interface: PackedArray

Appends a copy to the end of the array

Specified by:

append in interface PackedArray<TupleDesc_B>

Parameters:

element - (Input) The element which is copied then added

set

 TupleDesc_B element)

Description copied from interface: PackedArray

Sets an element's value

Specified by:

set in interface PackedArray<TupleDesc_B>

getTemp

public TupleDesc_B getTemp(int index)

Specified by:

getTemp in interface LArrayAccessor<TupleDesc_B>

getCopy
