NAME Tie::OffsetArray - Tie one array to another, with index offset SYNOPSIS use Tie::OffsetArray; tie @a, 'Tie::OffsetArray', 1, \@b; # offset=1; use given array. tie @c, 'Tie::OffsetArray', 2; # use anonymous array. $a[0] = 'x'; # assign to $b[1]; tied(@a)->array->[0] = 'y'; # assign to $b[0]. DESCRIPTION When tied to this class, an array's behavior is completely normal. For its internal storage, it uses another array, either one supplied by the caller, or a new anonymous one. Accesses to the tied array are mapped down to the storage array by offsetting the index by some constant amount. A special method on the tied object returns a reference to the storage array, so that the elements below the offset can be accessed. This is particularly useful if the storage array was not supplied by the caller. AUTHOR jdporter@min.net (John Porter) COPYRIGHT This is free software.
