new(%parameters)
auto_flush
Auto flush flag. Default value is 0.
input_tags_item_callback
Input 'Tags' item callback. Callback is processing before main 'Tags' put(). It's usefull for e.g. validation. Default value is undef.
output_callback
Output callback. Default value is callback which encode to output encoding, if parameter 'output_encoding' is present. Arguments of callback: - $data_sr - Reference to data - $self - Object Example for output encoding in iso-8859-2: 'output_callback' => sub { my ($data_sr, $self) = @_; ${$data_sr} = encode('iso-8859-2', ${$data_sr}); return; }
output_encoding
Output encoding. Default value is undef, which mean not encode.
output_handler

output_sep
Output separator. Default value is newline (\n).
skip_bad_tags
Skip bad tags. Default value is 0.
strict_instruction
Strict instruction. Default value is 1.
finalize()
Finalize Tags output. Automaticly puts end of all opened tags. Returns undef.
flush($reset_flag)
Flush tags in object. If defined 'output_handler' flush to its. Or return code. If enabled $reset_flag, then resets internal variables via reset method.
open_elements()

put(@data)
Put tags code in tags format. Returns undef.
reset($reset_flag)

Instruction. Method can write output to 'flush_code' object parameter as array or scalar. Returns undef.
_put_raw(@raw_data)
Raw data. Method can write output to 'flush_code' object parameter as array or scalar. Returns undef.
