Method Detail

get

E get(int input)

Get the calculate value for index based on the previous stream.

So it just calls invoke(getInputStream().get(index), index)

Parameters:

index - in

Returns:

getIndex

int getIndex()

Index of last successfully processed element.

getLast

int getLast()

Last possible element.
If last is not known then this is set to LAST_UNKNOWN.
When you add a new element this will not grow.
When maxLast is set so it this, but this can can get lower.
Set when you find the end.

If you use this for iteration you need to call the function at each iteration.

getMaxLast

int getMaxLast()

Manually set max value for last possible element.

setMaxLast

void setMaxLast(int maxLast)

Set a max value for last possible element.
