NAME

LINQ::FieldSet - base class for LINQ::FieldSet::{Selection,Assertion}

DESCRIPTION

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.

CONSTRUCTOR

new( ARGSLIST )

Constructs a fieldset from a list of fields like:

  'LINQ::FieldSet'->new(
    'field1', -param1 => 'value1', -param2,
    'field2', -param1 => 'value2',
  );

The list of allowed parameters and whether each one takes a value is returned by the _known_parameter_names method. This is empty in LINQ::FieldSet itself so doing anything interesting with this class probably requires subclassing.

METHODS

fields

An arrayref of fields in this fieldset.

fields_hash

The same, but as a hashref keyed on field name.

seen_asterisk

Whether "*" was seen by the constructor.

BUGS

Please report any bugs to http://rt.cpan.org/Dist/Display.html?Queue=LINQ.
