92
|
|
|
|
|
|
|
|
93
|
|
|
|
|
|
|
This is used internally by LINQ and you probably don't need to know about it |
94
|
|
|
|
|
|
|
unless you're writing very specific extensions for LINQ. |

|
|
|
|
|
Constructs a fieldset from a list of fields like: |
103
|
|
|
|
|
|
|
|
104
|
|
|
|
|
|
|
'LINQ::FieldSet'->new( |
105
|
|
|
|
|
|
|
'field1', -param1 => 'value1', -param2, |
106
|
|
|
|
|
|
|
'field2', -param1 => 'value2', |
107
|
|
|
|
|
|
|
); |
108
|
|
|
|
|
|
|
|
109
|
|
|
|
|
|
|
The list of allowed parameters and whether each one takes a value is returned |
110
|
|
|
|
|
|
|
by the C<_known_parameter_names> method. This is empty in LINQ::FieldSet itself |
111
|
|
|
|
|
|
|
so doing anything interesting with this class probably requires subclassing. |
