Field Details

from

private final N extends Number & Comparable<N> from

to

private final N extends Number & Comparable<N> to

step

private final N extends Number & Comparable<N> step

closed

private final boolean closed

current

private N extends Number & Comparable<N> current

sign

private final int sign

private final N extends Number & Comparable<N> zero

Constructor Details

Range

Range(N from,
 N to,
 N step,
 boolean closed,
 N zero)

Method Details

validate

void validate()

Asserts the range is valid.

Throws:

IllegalArgumentException - if the range is not valid

isValidDescending

boolean isValidDescending()

getStep

N getStep()

getCurrent

N getCurrent()

nextValue

abstract N nextValue()

The next value in the range. Calling next() will return this value and advance the iterator to it.

getNextValue

private N getNextValue()

getZero

private N getZero()

The value of the no-op "zero", illegal step in terms of N

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<N extends Number & Comparable<N>>

next

public N next()

Specified by:

next in interface Iterator<N extends Number & Comparable<N>>
