NAME
Config::AST::Node::Value - simple statement node
DESCRIPTION
Implements a simple statement node. Simple statement is always associated with a value, hence the class name.
METHODS
$node->value
Returns the value associated with the statement.
If value is a code reference, it is invoked without arguments, and its return is used as value.
If the value is a reference to a list or hash, the return depends on the context. In scalar context, the reference itself is returned. In list context, the array or hash is returned.
bool = $node->is_leaf
Returns false.
$s = $node->as_string
Returns the node value, converted to string.
$s = $node->as_number
Returns the node value, converted to number.
If the value is an array, returns number of elements in the array. If the value is a hash, returns number of keys. Otherwise, returns the value itself.
CONTEXT-SENSITIVE COERCIONS
Depending on the context in which it is used, the Config::AST::Node::Value is coerced to the most appropriate data type. For example, in the following expression;
if ($cf->getnode('offset') < 10) {
...
}the value will be coerced to a number prior to comparison. This means that in most cases you don't need to explicitly invoke the value method.
