Bio::Tools::StateMachine::IOStateMachine - IO-based implementation of AbstractStateMachine
use Bio::Tools::StateMachine::IOStateMachine; # A state machine that reads input from a file my $sm = Bio::Tools::StateMachine::IOStateMachine->new( -file => 'data.txt' ); # A state machine that reads input from a STDIN my $sm = Bio::Tools::StateMachine::IOStateMachine->new(); # A state machine that reads input from a STDIN # and times out if input doesn't arrive within 30 seconds. my $sm = Bio::Tools::StateMachine::IOStateMachine->new( -timeout_sec => 30 );
An implementation of AbstractStateMachine that samples an input stream to determine whether a state change has occurred.
To get a feel for how to use this, have look at Bio::SearchIO::psiblast which subclasses IOStateMachine.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Argument : Named parameter -TIMEOUT_SEC => seconds, to specify the number of seconds to allow before throwing an exception if input fails to arrive within that amount of time.
Purpose : Obtains data from the input stream to be checked for the existence of a new state. Usage : check_for_new_state( [$ignore_blank_lines] ); Argument : boolean: true if you want to ignore blank lines Returns : the next chunk of input ($/ is not altered) If there is no more input, returns undef.
Subclasses should override this method and call it to obtain the chunk of data for new state testing.
Argument : n/a Returns : The next chunk of input data from the IO stream To be used in determining what state the machine should be in.
