def initialize(predicates)
	@predicates = predicates
end

`def print(output)`

Print a representation of this predicate.

Signature

parameter　output　Output: The output target.

Implementation

def print(output)
	first = true
	output.write("have any {")
	@predicates.each do |predicate|
		if first
			first = false
		else
			output.write(", ")
		end
		
		output.write(predicate)
	end
	output.write("}")
end

`def call(assertions, subject)`

Signature

parameter　assertions　Assertions: The assertions instance to use.
parameter　subject　Object: The subject to evaluate.

Implementation

def call(assertions, subject)
	assertions.nested(self) do |assertions|
		@predicates.each do |predicate|
			predicate.call(assertions, subject)
		end
		
		if assertions.passed.any?
			# We don't care about any failures in this case, as long as one of the values passed:
			assertions.failed.clear
		else
			# Nothing passed, so we failed:
			assertions.assert(false, "could not find any matching value")
		end
