Implementation

dc.bool contains(dc.Object? e$1, ){
final lcoc_core.PersistentHashMap<E, E> o7775$1=hm;
final dc.dynamic k7776$1=e$1;
if((o7775$1 is lcoc_core.ILookup$iface)){
return ((o7775$1 as lcoc_core.ILookup$iface).$_contains_key$QMARK_$1(k7776$1, ));
}
return ((lcoc_core.ILookup.extensions(o7775$1, ) as lcoc_core.ILookup$ext).$_contains_key$QMARK_$1(o7775$1, k7776$1, ));
}
