`class And`

Represents a logical AND combination of multiple predicates.

Definitions

`def initialize(predicates)`

Initialize a new AND predicate.

Signature

parameter　predicates　Array: The predicates to combine with AND logic.

Implementation

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)
	@predicates.each_with_index do |predicate, index|
		if index > 0
			output.write(" and ", :reset)
		end
		
		predicate.print(output)
	end
end

`def call(assertions, subject)`

Evaluate this predicate against a subject.

Signature

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

Implementation

def call(assertions, subject)
	@predicates.each do |predicate|
		predicate.call(assertions, subject)
	end
end

`def &(other)`

Combine this predicate with another using AND logic.

Signature

parameter　other　Object: Another predicate to combine.
returns　And: A new AND predicate.

Implementation

def &(other)
	And.new(@predicates + [other])
end

`def |(other)`

Combine this predicate with another using OR logic.

Signature

parameter　other　Object: Another predicate to combine.
returns　Or: A new OR predicate.

Implementation

def |(other)
	Or.new([self, other])
end
