Method Detail

getNoEntryValue

double getNoEntryValue()

Returns the value that is used to represent null. The default value is generally zero, but can be configured during construction of the collection.

Returns:

the value that represents null

Returns:

an double value

size

int size()

Returns the current depth of the stack.

clear

void clear()

toArray

double[] toArray()

Copies the contents of the stack into a native array. Note that this will NOT pop them out of the stack.

Returns:

an double[] value

toArray

void toArray(double[] dest)

Copies a slice of the list into a native array. Note that this will NOT pop them out of the stack.
