VirtualMatrix

class VirtualMatrix<out T : Any>(rowNum: Int, colNum: Int, generator: (i: Int, j: Int) -> T) : Structure2D<T>

The matrix where each element is evaluated each time when is being accessed.

Functions

elements

common

@PerformancePitfall()

open override fun elements(): Sequence<Pair<IntArray, T>>

Returns the sequence of all the elements associated by their indices.

get

common

open operator override fun get(index: IntArray): T

Returns the value at the specified indices.

open operator override fun get(i: Int, j: Int): T

Retrieves an element from the structure by two indices.

getFeature

common

open override fun <F : StructureFeature> getFeature(type: KClass<out F>): F?

Feature is some additional structure information that allows to access it special properties or hints.
