Class org.hipparchus.util.ResizableDoubleArray

class ResizableDoubleArray extends Object implements Serializable

serialVersionUID:

20160327L

Serialized Fields

contractionCriterion

double contractionCriterion

The contraction criteria determines when the internal array will be contracted to fit the number of elements contained in the element array + 1.

expansionFactor

double expansionFactor

The expansion factor of the array. When the array needs to be expanded, the new array size will be internalArray.length * expansionFactor if expansionMode is set to MULTIPLICATIVE, or internalArray.length + expansionFactor if expansionMode is set to ADDITIVE.

expansionMode

ResizableDoubleArray.ExpansionMode expansionMode

Determines whether array expansion by expansionFactor is additive or multiplicative.

internalArray

double[] internalArray

The internal storage array.

numElements

int numElements

The number of addressable elements in the array. Note that this has nothing to do with the length of the internal storage array.

startIndex

int startIndex

The position of the first addressable element in the internal storage array. The addressable elements in the array are internalArray[startIndex],...,internalArray[startIndex + numElements - 1].
