NAME
Bio::OntologyIO::Handlers::BaseSAXHandler base class for SAX HandlersSYNOPSIS
See description.DESCRIPTION
This module is an abstract module, serving as the base of any SAX Handler implementation. It tries to offer the framework that SAX handlers generally need, such as tag_stack, char_store, etc.In the implementation handler, you can take advantage of this based module by the following suggestions.
1) In start_element,
sub start_element { my $self=shift; my $tag=$_[0]->{Name}; my %args=%{$_[0]->{Attributes}}; # Your code here. # Before you conclude the method, write these 2 line. $self->_visited_count_inc($tag); $self->_push_tag($tag); }
2) In end_element,
sub end_element { my $self=shift; my $tag=shift->{Name}; # Your code here. # Before you conclude the method, write these 2 lines. $self->_visited_count_dec($tag); $self->_pop_tag; }
3) In characters, or any other methods where you may use the tag stack or count
sub characters { my $self=shift; my $text=shift->{Data}; $self->_chars_hash->{$self->_top_tag} .= $text; } $count = $self->_visited_count('myTag'); $tag = $self->_top_tag;

The rest of the documentation details each of the object methods. Interal methods are usually preceded with a __tag_stack
Title : _tag_stack Usage : @tags = $self->_tag_stack; Function: Get an array of tags that have been accessed but not enclosed. Return : Args :
_push_tag
_pop_tag
_top_tag
Title : _top_tag Usage : $top = $self->_top_tag; Function: get the top tag in the tag stack. Return : a tag name Args : [none]
_chars_hash
Title : _chars_hash Usage : $hash= $self->_chars_hash; Function: return the character cache for the specific tag Return : a hash reference, which is intent for character storage for tags Args : [none]
_current_hash
_visited_count_inc
Title : _vistied_count_inc Usage : $self->vistied_count_inc($tag); # the counter for the tag increase Function: the counter for the tag increase Return : the current count after this increment Args : the tag name [scalar]
_visited_count_dec
Title : _visited_count_dec Usage : $self->_visited_count_dec($tag); Function: the counter for the tag decreases by one Return : the current count for the specific tag after the decrement Args : the tag name [scalar]
_visited_count
Title : _visited_count Usage : $count = $self->_visited_count Function: return the counter for the tag Return : the current counter for the specific tag Args : the tag name [scalar]
