A Resolver::Specification contains a subset of the information contained in a Gem::Specification. Only the information necessary for dependency resolution in the resolver is included.

A VendorSpecification represents a gem that has been unpacked into a project and is being loaded through a gem dependencies file through the path: option.

Gem::Security default exception type

An object representation of a stack frame, initialized by Kernel#caller_locations.

For example:

# caller_locations.rb
def a(skip)
  caller_locations(skip)
end
def b(skip)
  a(skip)
end
def c(skip)
  b(skip)
end

c(0..2).map do |call|
  puts call.to_s
end

Running ruby caller_locations.rb will produce:

caller_locations.rb:2:in `a'
caller_locations.rb:5:in `b'
caller_locations.rb:8:in `c'

Here’s another example with a slightly different result:

# foo.rb
class Foo
  attr_accessor :locations
  def initialize(skip)
    @locations = caller_locations(skip)
  end
end

Foo.new(0..2).locations.map do |call|
  puts call.to_s
end

Now run ruby foo.rb and you should see:

init.rb:4:in `initialize'
init.rb:8:in `new'
init.rb:8:in `<main>'

standard dynamic load exception

The Fiddle::Handle is the manner to access the dynamic library

Example

Setup

libc_so = "/lib64/libc.so.6"
=> "/lib64/libc.so.6"
@handle = Fiddle::Handle.new(libc_so)
=> #<Fiddle::Handle:0x00000000d69ef8>

Setup, with flags

libc_so = "/lib64/libc.so.6"
=> "/lib64/libc.so.6"
@handle = Fiddle::Handle.new(libc_so, Fiddle::RTLD_LAZY | Fiddle::RTLD_GLOBAL)
=> #<Fiddle::Handle:0x00000000d69ef8>

See RTLD_LAZY and RTLD_GLOBAL

Addresses to symbols

strcpy_addr = @handle['strcpy']
=> 140062278451968

or

strcpy_addr = @handle.sym('strcpy')
=> 140062278451968

Generic error, common for all classes under OpenSSL module

If an object defines encode_with, then an instance of Psych::Coder will be passed to the method when the object is being serialized. The Coder automatically assumes a Psych::Nodes::Mapping is being emitted. Other objects like Sequence and Scalar may be emitted if seq= or scalar= are called, respectively.

Psych::Handler is an abstract base class that defines the events used when dealing with Psych::Parser. Clients who want to use Psych::Parser should implement a class that inherits from Psych::Handler and define events that they can handle.

Psych::Handler defines all events that Psych::Parser can possibly send to event handlers.

See Psych::Parser for more details

Zlib::GzipFile is an abstract class for handling a gzip formatted compressed file. The operations are defined in the subclasses, Zlib::GzipReader for reading, and Zlib::GzipWriter for writing.

GzipReader should be used by associating an IO, or IO-like, object.

A CSV::Table is a two-dimensional data structure for representing CSV documents. Tables allow you to work with the data by row or column, manipulate the data, and even convert the results back to CSV, if needed.

All tables returned by CSV will be constructed from this class, if header row processing is activated.
