8.158 Tie::SubstrHash

Provides a hash-table-like interface to a fixed-sized array that has a constant key size and record size.

require Tie::SubstrHash;
tie %myhash, "Tie::SubstrHash", key_len, value_len, table_size;
To tie a new hash to this package, specify the following:


Length of each key


Length of each value


Size of the table given as the number of key/value pairs

An attempt to store a key/value pair where either the key or the value is the wrong length, or where the resulting table would be greater than table_size, results in a fatal error.
