PDF::API3::Compat::APIUseraContributedAPerl:Dompat::API2::Basic::TTF::Table(3)

NAME
       PDF::API3::Compat::API2::Basic::TTF::Table - Superclass for tables and
       used for	tables we don't	have a class for

DESCRIPTION
       Looks after the purely table aspects of a TTF table, such as whether
       the table has been read before, locating	the file pointer, etc. Also
       copies tables from input	to output.

INSTANCE VARIABLES
       Instance	variables start	with a space

       read
	   Flag	which indicates	that the table has already been	read from
	   file.

       dat Allows the creation of unspecific tables. Data is simply output to
	   any font file being created.

       INFILE
	   The read file handle

       OFFSET
	   Location of the file	in the input file

       LENGTH
	   Length in the input directory

       CSUM
	   Checksum read from the input	file's directory

       PARENT
	   The PDF::API3::Compat::API2::Basic::TTF::Font that table is part of

METHODS
   PDF::API3::Compat::API2::Basic::TTF::Table->new(%parms)
       Creates a new table or subclass.	Table instance variables are passed in
       at this point as	an associative array.

   $t->read
       Reads the table from the	input file. Acts as a superclass to all	true
       tables.	This method marks the table as read and	then just sets the
       input file pointer but does not read any	data. If the table has already
       been read, then returns "undef" else returns $self

   $t->read_dat
       Reads the table into the	"dat" instance variable	for those tables which
       don't know any better

   $t->out($fh)
       Writes out the table to the font	file. If there is anything in the
       "data" instance variable	then this is output, otherwise the data	is
       copied from the input file to the output

   $t->out_xml($context)
       Outputs this table in XML format. The table is first read (if not
       already read) and then if there is no subclass, then the	data is	dumped
       as hex data

   $t->XML_element
       Output a	particular element based on its	contents.

   $t->XML_end($context, $tag, %attrs)
       Handles the default type	of <data> for those tables which aren't
       subclassed

   $t->dirty($val)
       This sets the dirty flag	to the given value or 1	if no given value. It
       returns the value of the	flag

   $t->update
       Each table knows	how to update itself. This consists of doing whatever
       work is required	to ensure that the memory version of the table is
       consistent and that other parameters in other tables have been updated
       accordingly.  I.e. by the end of	sending	"update" to all	the tables,
       the memory version of the font should be	entirely consistent.

       Some tables which do no work indicate to	themselves the need to update
       themselves by setting isDirty above 1. This method resets that
       accordingly.

   $t->empty
       Clears a	table of all data to the level of not having been read

   $t->release
       Releases	ALL of the memory used by this table, and all of its
       component/child objects.	 This method is	called automatically by
       '"PDF::API3::Compat::API2::Basic::TTF::Font-E<GT>release"' (so you
       don't have to call it yourself).

       NOTE, that it is	important that this method get called at some point
       prior to	the actual destruction of the object.  Internally, we track
       things in a structure that can result in	circular references, and
       without calling '"release()"' these will	not properly get cleaned up by
       Perl.  Once this	method has been	called,	though,	don't expect to	be
       able to do anything with	the
       "PDF::API3::Compat::API2::Basic::TTF::Table" object; it'll have no
       internal	state whatsoever.

       Developer note:	As part	of the brute-force cleanup done	here, this
       method will throw a warning message whenever unexpected key values are
       found within the	"PDF::API3::Compat::API2::Basic::TTF::Table" object.
       This is done to help ensure that	any unexpected and unfreed values are
       brought to your attention so that you can bug us	to keep	the module
       updated properly; otherwise the potential for memory leaks due to
       dangling	circular references will exist.

BUGS
       No known	bugs
