NAME

Bio::Phylo::Matrices::TypeSafeData - Superclass for objects that hold character data.

SYNOPSIS

 # No direct usage

DESCRIPTION

This is a superclass for objects holding character data. Objects that inherit from this class (typically matrices and datum objects) yield functionality to handle datatype objects and use them to validate data such as DNA sequences, continuous data etc.

METHODS

CONSTRUCTOR

new()

 Type    : Constructor
 Title   : new
 Usage   : No direct usage, is called by child class;
 Function: Instantiates a Bio::Phylo::Matrices::TypeSafeData
 Returns : a Bio::Phylo::Matrices::TypeSafeData child class
 Args    : -type    => (data type - required)
           Optional:
           -missing => (the symbol for missing data)
           -gap     => (the symbol for gaps)
           -lookup  => (a character state lookup hash)
           -type_object => (a datatype object)

MUTATORS

set_type()

 Type    : Mutator
 Title   : set_type
 Usage   : $obj->set_type($type);
 Function: Sets the object's datatype.
 Returns : Modified object.
 Args    : Argument must be a string, one of
           continuous, custom, dna, mixed,
           protein, restriction, rna, standard

set_missing()

 Type    : Mutator
 Title   : set_missing
 Usage   : $obj->set_missing('?');
 Function: Sets the symbol for missing data
 Returns : Modified object.
 Args    : Argument must be a single
           character, default is '?'

set_gap()

 Type    : Mutator
 Title   : set_gap
 Usage   : $obj->set_gap('-');
 Function: Sets the symbol for gaps
 Returns : Modified object.
 Args    : Argument must be a single
           character, default is '-'

set_lookup()

 Type    : Mutator
 Title   : set_lookup
 Usage   : $obj->set_gap($hashref);
 Function: Sets the symbol for gaps
 Returns : Modified object.
 Args    : Argument must be a hash
           reference that maps allowed
           single character symbols
           (including ambiguity symbols)
           onto the equivalent set of
           non-ambiguous symbols

set_type_object()

 Type    : Mutator
 Title   : set_type_object
 Usage   : $obj->set_gap($obj);
 Function: Sets the datatype object
 Returns : Modified object.
 Args    : Argument must be a subclass
           of Bio::Phylo::Matrices::Datatype

ACCESSORS

get_type()

 Type    : Accessor
 Title   : get_type
 Usage   : my $type = $obj->get_type;
 Function: Returns the object's datatype
 Returns : A string
 Args    : None

get_missing()

 Type    : Accessor
 Title   : get_missing
 Usage   : my $missing = $obj->get_missing;
 Function: Returns the object's missing data symbol
 Returns : A string
 Args    : None

get_gap()

 Type    : Accessor
 Title   : get_gap
 Usage   : my $gap = $obj->get_gap;
 Function: Returns the object's gap symbol
 Returns : A string
 Args    : None

get_lookup()

 Type    : Accessor
 Title   : get_lookup
 Usage   : my $lookup = $obj->get_lookup;
 Function: Returns the object's lookup hash
 Returns : A hash reference
 Args    : None

get_type_object()

 Type    : Accessor
 Title   : get_type_object
 Usage   : my $obj = $obj->get_type_object;
 Function: Returns the object's linked datatype object
 Returns : A subclass of Bio::Phylo::Matrices::Datatype
 Args    : None

INTERFACE METHODS

validate()

 Type    : Interface method
 Title   : validate
 Usage   : $obj->validate
 Function: Validates the object's contents
 Returns : True or throws Bio::Phylo::Util::Exceptions::InvalidData
 Args    : None
 Comments: This is an interface method, i.e. this class doesn't
           implement the method, child classes have to

SEE ALSO

Bio::Phylo

This object inherits from Bio::Phylo, so the methods defined therein are also applicable to Bio::Phylo::Matrices::TypeSafeData objects.
