NAME¶
Cucumber::TagExpressions::Node - Cucumber Tag expression components
SYNOPSIS¶
use Cucumber::TagExpressions; my $expr = Cucumber::TagExpressions->parse( '@a and @b' ); if ( $expr->evaluate( qw/x y z/ ) ) { say "The evaluation returned false"; }
DESCRIPTION¶
This module defines the components making up the tag expressions.
METHODS¶
evaluate( @tags )¶
Returns "true" when the tag set specified in $tags satisfies the condition(s) of the expression, "false" otherwise.
@tags can be a list of tags to be used in the expression. It can also be a reference to a hash with the keys being the tags and the values being considered boolean values indicating whether the tag (key) is considered part of the tagset (true) or not (false).
stringify¶
Returns a string representation of the expression node.
NODE CLASSES¶
Cucumber::TagExpressions::LiteralNode¶
DESCRIPTION
This node class returns "true" if the literal tag is specified as part of the tag-list in the expression evaluation.
ATTRIBUTES
tag
The tag to test presence for.
Cucumber::TagExpressions::AndNode¶
DESCRIPTION
This node class type evaluates one or more sub-expressions ("terms") and returns "false" if any of the terms does. It returns "true" if all of the terms return "true".
ATTRIBUTES
terms
The sub-expressions to evaluate.
Cucumber::TagExpressions::OrNode¶
DESCRIPTION
This node class type evaluates one or more sub-expressions ("terms") and returns "true" if any of the terms does. It returns "false" if all of the terms return "false".
ATTRIBUTES
terms
The sub-expressions to evaluate.
Cucumber::TagExpressions::NotNode¶
DESCRIPTION
This class wraps one of the other node class types, negating its result on evaluation.
ATTRIBUTES
expression
The wrapped node class instance for which to negate the result.
Cucumber::TagExpressions::ExpressionNode¶
DESCRIPTION
This class models the outer-most node in the tag expression; it wraps all other nodes and is the entry-point for tag expression evaluation.
ATTRIBUTES
sub_expression
An instance of one of the other node class types.
