| Return the next random number in the sequence generated by this object.
| xref:BloombergLP/bdlb/PcgRandomGenerator/seed.adoc[`seed`] 
| Seed this generator with the specified new `initState` and `streamSelector`. Note that the sequence of random numbers produced from subsequent invocations of `generate()` will be the same as that produced by an object created by `PcgRandomGenerator(initState, streamSelector)`.

| Name| Description
| `xref:BloombergLP/bdlb/operator_eq-04c.adoc[BloombergLP::bdlb::operator==]`
| Return `true` if the specified `lhs` and `rhs` objects have the same value, and `false` otherwise. Two `PcgRandomGenerator` objects have the same value if they would produce the same sequence of random numbers from subsequent invocations of `generate()`.

| Name| Description
| xref:BloombergLP/bdlb/operator_not_eq-0a6.adoc[`operator!=`]
| Return `true` if the specified `lhs` and `rhs` objects do not have the same value, and `false` otherwise. Two `PcgRandomGenerator` objects do not have the same value if they would not produce the same sequence of random numbers from subsequent invocations of `generate()`.
