Method Detail

create

public static <T> Range<T> create(T lower,
                                  T upper)

Create a new range from lower and upper boundary values. Both values are included (greater than or equals and less than or equals).

Type Parameters:

T - value type

Parameters:

lower - lower boundary, must not be null.

upper - upper boundary, must not be null.

Returns:

new Range

from

public static <T> Range<T> from(Range.Boundary<T> lower,
                                Range.Boundary<T> upper)

Create a new range from lower and upper boundaries.

Type Parameters:

T - value type.

Parameters:

lower - lower boundary, must not be null.

upper - upper boundary, must not be null.

Returns:

new Range

unbounded

public static <T> Range<T> unbounded()

Type Parameters:

T - value type.

Returns:

new Range with lower and upper set to Range.Boundary.unbounded().

gte

public Range<T> gte(T lower)

Greater than or equals lower.

Parameters:

lower - the lower boundary value.

Returns:

this Range with lower applied.

gt

public Range<T> gt(T lower)

Greater than lower.

Parameters:

lower - the lower boundary value.

Returns:

this Range with lower applied.

lte

public Range<T> lte(T upper)

Less than or equals lower.

Parameters:

upper - the upper boundary value.

Returns:

this Range with upper applied.

lt

public Range<T> lt(T upper)

Less than lower.

Parameters:

upper - the upper boundary value.

Returns:

this Range with upper applied.

isUnbounded

public boolean isUnbounded()

Return whether this Range is unbounded (i.e. upper and lower bounds are unbounded).

Returns:

whether this Range is unbounded

Since:

6.0
