"DELETE" Hash delete. "EXISTS" Hash exists. "FETCH" Hash fetch. "FIRSTKEY" Hash first key. "NEXTKEY" Hash nextkey. "SCALAR" Hash scalar. "STORE" Hash store. ERRORS TIEHASH(): Parameter isn't hash. Stack isn't array. FETCH(): Key '%s' doesn't exist. EXAMPLE use strict; use warnings; use Tie::Hash::Check; # Set error type. $ENV{'ERROR_PURE_TYPE'} = 'Print'; # Tied hash. tie my %hash, 'Tie::Hash::Check', { 'one' => 1, 'two' => 2, }; # Turn error "Key 'three' doesn't exist.". print $hash{'three'}; # Output: # Tie::Hash::Check: Key 'three' doesn't exist.
