NAME
LINQ::FieldSet::Single - similar to LINQ::FieldSet::Selection, but only selects one field
DESCRIPTION
LINQ::FieldSet::Single is a subclass of LINQ::FieldSet.
This is used internally by LINQ and you probably don't need to know about it unless you're writing very specific extensions for LINQ. The end user interface is the field function in LINQ::Util.
CONSTRUCTOR
new( NAME, EXTRAARGS )-
Constructs a fieldset like:
'LINQ::FieldSet::Single'->new( 'name', @stuff );If called in scalar context, and
@stuffisn't the empty list, then will throw an exception.If called in list context, will return the newly constructed object followed by unadulterated
@stuff.
METHODS
coderef-
Gets a coderef for this assertion; the coderef operates on
$_. to_string-
Basic string representation of the fieldset.
OVERLOADING
This class overloads "" to call the to_string method and &{} to call the coderef method.
