Create a new ConstantReadNode node
returns an integer in (-infty, 0] a number closer to 0 means the dependency is less constraining
dependencies w/ 0 or 1 possibilities (ignoring version requirements) are given very negative values, so they always sort first, before dependencies that are unconstrained
Compile a ConstantReadNode node
Dispatch enter and leave events for ConstantReadNode nodes and continue walking the tree.
Indicated, based on the requested domain, if remote gems should be considered.
Verify compaction reference consistency.
This method is implementation specific. During compaction, objects that were moved are replaced with T_MOVED objects. No object should have a reference to a T_MOVED object after compaction.
This function expands the heap to ensure room to move all objects, compacts the heap to make sure everything moves, updates all references, then performs a full GC. If any object contains a reference to a T_MOVED object, that object should be pushed on the mark stack, and will make a SEGV.
Returns true if the contents of streams a and b are identical, false otherwise.
Arguments a and b should be interpretable as a path.

Returns true if the given argument is within self, false otherwise.
With non-range argument object, evaluates with <= and <.
For range self with included end value (#exclude_end? == false), evaluates thus:
self.begin <= object <= self.end
Examples:
r = (1..4) r.cover?(1) # => true r.cover?(4) # => true r.cover?(0) # => false r.cover?(5) # => false r.cover?('foo') # => false r = ('a'..'d') r.cover?('a') # => true r.cover?('d') # => true r.cover?(' ') # => false r.cover?('e') # => false r.cover?(0) # => false
For range r with excluded end value (#exclude_end? == true), evaluates thus:
r.begin <= object < r.end
Examples:
r = (1...4) r.cover?(1) # => true r.cover?(3) # => true r.cover?(0) # => false r.cover?(4) # => false r.cover?('foo') # => false r = ('a'...'d') r.cover?('a') # => true r.cover?('c') # => true r.cover?(' ') # => false r.cover?('d') # => false r.cover?(0) # => false
With range argument range, compares the first and last elements of self and range:
r = (1..4) r.cover?(1..4) # => true r.cover?(0..4) # => false r.cover?(1..5) # => false r.cover?('a'..'d') # => false r = (1...4) r.cover?(1..3) # => true r.cover?(1..4) # => false
If begin and end are numeric, cover? behaves like include?
(1..3).cover?(1.5) # => true (1..3).include?(1.5) # => true
But when not numeric, the two methods may differ:
('a'..'d').cover?('cc') # => true ('a'..'d').include?('cc') # => false
Returns false if either:
The begin value of self is larger than its end value.
An internal call to <=> returns nil; that is, the operands are not comparable.
Beginless ranges cover all values of the same type before the end, excluding the end for exclusive ranges. Beginless ranges cover ranges that end before the end of the beginless range, or at the end of the beginless range for inclusive ranges.
(..2).cover?(1) # => true (..2).cover?(2) # => true (..2).cover?(3) # => false (...2).cover?(2) # => false (..2).cover?("2") # => false (..2).cover?(..2) # => true (..2).cover?(...2) # => true (..2).cover?(.."2") # => false (...2).cover?(..2) # => false
Endless ranges cover all values of the same type after the beginning. Endless exclusive ranges do not cover endless inclusive ranges.
(2..).cover?(1) # => false (2..).cover?(3) # => true (2...).cover?(3) # => true (2..).cover?(2) # => true (2..).cover?("2") # => false (2..).cover?(2..) # => true (2..).cover?(2...) # => true (2..).cover?("2"..) # => false (2...).cover?(2..) # => false (2...).cover?(3...) # => true (2...).cover?(3..) # => false (3..).cover?(2..) # => false
Ranges that are both beginless and endless cover all values and ranges, and return true for all arguments, with the exception that beginless and endless exclusive ranges do not cover endless inclusive ranges.
(nil...).cover?(Object.new) # => true (nil...).cover?(nil...) # => true (nil..).cover?(nil...) # => true (nil...).cover?(nil..) # => false (nil...).cover?(1..) # => false
