Raises when there is an argument for a switch which takes no argument.
An abstract class for enumerating pseudo-prime numbers.
Concrete subclasses should override succ, next, rewind.
An implementation of PseudoPrimeGenerator which uses a prime table generated by trial division.
Generates all integers which are greater than 2 and are not divisible by either 2 or 3.
This is a pseudo-prime generator, suitable on checking primality of an integer by brute force method.
Internal use. An implementation of Eratosthenes’ sieve
This is an abstract class. You never use this directly; it serves as a parent class for the specific declarations.
An SimpleRenewer allows a TupleSpace to check if a TupleEntry is still alive.
Raised when a conversion failure occurs.
Raised when a RSS::Maker attempts to use an unknown maker.
Raised when trying to activate a gem, and the gem exists on the system, but not the requested version. Instead of rescuing from this class, make sure to rescue from the superclass Gem::LoadError to catch all types of load errors.
Raised by Gem::Resolver when a Gem::Dependency::Conflict reaches the toplevel. Indicates which dependencies were incompatible through conflict and conflicting_dependencies
Signals that a file permission error is preventing the user from operating on the given directory.
Raised by Gem::Validator when something is not right in a gem.
Not a URI component.
Raised when a mathematical function is evaluated outside of its domain of definition.
For example, since cos returns values in the range -1..1, its inverse function acos is only defined on that interval:
Math.acos(42)
produces:
Math::DomainError: Numerical argument is out of domain - "acos"
Raised when an invalid operation is attempted on a Fiber, in particular when attempting to call/resume a dead fiber, attempting to yield from the root fiber, or calling a fiber across threads.
fiber = Fiber.new{} fiber.resume #=> nil fiber.resume #=> FiberError: dead fiber called
