== BDB::Sequence
# module BDB
#^
A sequence is created with BDB::Common::create_sequence or
BDB::Common::open_sequence (only with db >= 4.3)
#^
=== class BDB::Common
--- create_sequence(key, init = nil, options = {}) {|sequence| }
create a new sequence (see also ((|open_sequence|)))
equivalent to
((|open_sequence(key, BDB::CREATE|BDB::EXCL, init, options)|))
return (or yield) an object BDB::Sequence
--- open_sequence(key, flags = 0, init = nil, options = {}) {|sequence| }
create or open a sequence (see BDB::Sequence)
((|key|)) : key for the sequence
((|flags|)) : flags can have BDB::CREATE, BDB::EXCL, BDB::AUTO_COMMIT,
BDB::THREAD
((|init|)) : initial value for the sequence
((|options|)) : hash with the possible keys "set_cachesize",
"set_flags" and "set_range"
return (or yield) an object BDB::Sequence
#^
# class Sequence
=== Methods
--- cachesize
return the current cache size
--- close
close the sequence
--- db
return the bdb file associated with the sequence
--- flags
return the current flags
--- get(delta = 1, flags = 0)
return the next available element in the sequence and changes
the sequence value by ((|delta|))
((|flags|)) can have the value BDB::AUTO_COMMIT, BDB::TXN_NOSYNC
--- key
return the key associated with the sequence
--- range
return the range of values in the sequence
--- remove(flags = 0)
remove the sequence
((|flags|)) can have the value BDB::AUTO_COMMIT, BDB::TXN_NOSYNC
--- stat(flags = 0)
return statistics about the sequence
((|flags|)) can have the value BDB::STAT_CLEAR
