The default behavior is to simply call a method called I<property> |
90
|
|
|
|
|
|
|
on the internal doc() object. Subclasses should implement per-engine |
91
|
|
|
|
|
|
|
behavior. |

111
|
|
|
|
|
|
|
|
112
|
|
|
|
|
|
|
Returns the stored value for I<property> for the Result. Unlike |
113
|
|
|
|
|
|
|
get_property(), the value is always an arrayref, split |
114
|
|
|
|
|
|
|
on the libswish3 multi-value character. |
115
|
|
|
|
|
|
|
|
116
|
|
|
|
|
|
|
Example: |
117
|
|
|
|
|
|
|
|
118
|
|
|
|
|
|
|
my $val = $result->get_property('foo'); # "green\003blue" |
119
|
|
|
|
|
|
|
my $arrval = $result->get_property_array('foo'); # ['green', 'blue'] |
120
|
|
|
|
|
|
|
|
121
|
|
|
|
|
|
|
Note that return value will *always* be an arrayref, even if |
122
|
|
|
|
|
|
|
the original value does not contain a multi-value character. |
