Fyodor User Guide - Number Generators

Fyodor has generators for Integer, BigDecimal, Long and Double types.

Integer

RDG provides the following methods that return a Generator<Integer>:

RDG.integer();
RDG.integer(int);
RDG.integer(Range<Integer>);

RDG.integer().next() generates a random integer ranging from Integer.MIN_VALUE to Integer.MAX_VALUE.

RDG.integer(int).next() generates a random integer between 0 and the integer suppied.

RDG.integer(Range<Integer>).next() generates a random integer in the supplied Range<Integer>.

BigDecimal

RDG provides the following methods that return a Generator<BigDecimal>:

RDG.bigDecimal();
RDG.bigDecimal(double);
RDG.bigDecimal(long);
RDG.bigDecimal(BigDecimal);
RDG.bigDecimal(Range<BigDecimal>);
RDG.bigDecimal(Range<BigDecimal>, int);

RDG.bigDecimal().next() generates a BigDecimal ranging from Double.MIN_VALUE to Double.MAX_VALUE

RDG.bigDecimal(double).next() generates a BigDecimal with a scale of 2 ranging from 0 to the double supplied.

RDG.bigDecimal(long).next() generates a BigDecimal with a scale of 2 ranging from 0 to the long supplied.

RDG.bigDecimal(BigDecimal).next() generates a BigDecimal with a scale of 2 ranging from 0 to the BigDecimal supplied.

RDG.bigDecimal(Range<BigDecimal>).next() generates a BigDecimal with a scale of 2 in the Range<BigDecimal> supplied.

RDG.bigDecimal(Range<BigDecimal>, int).next() generates a BigDecimal in the Range<BigDecimal> supplied with a scale of the int supplied.

Double

RDG provides the following methods that return a Generator<Double>:

RDG.doubleVal();
RDG.doubleVal(double);
RDG.doubleVal(Range<Double>);

RDG.doubleVal().next() generates a Double ranging from Double.MIN_VALUE to Double.MAX_VALUE

RDG.doubleVal(double).next() generates a Double ranging from 0 to the double supplied.

RDG.doubleVal(Range<Double>).next() generates a Double in the Range<Double> supplied.

Long

RDG provides the following methods that return a Generator<Long>:

RDG.longVal();
RDG.longVal(long);
RDG.longVal(Range<Long>);

RDG.longVal().next() generates a Long ranging from Long.MIN_VALUE to Long.MAX_VALUE

RDG.longVal(long).next() generates a Long ranging from 0 to the long supplied.

RDG.longVal(Range<Long>).next() generates a Long in the Range<Long> supplied.
