NAME
Text::Same::FileChunkedSource
DESCRIPTION
Objects of this class represent a source of chunks (generally lines) in a file. The "chunks" could potentially be paragraphs or sentences.
SYNOPSIS
my $source = new Text::Same::FileChunkedSource(chunks->\@chunks)
METHODS
See below. Methods private to this module are prefixed by an underscore.
new
Title : new
Usage : $source = new Text::Same::FileChunkedSource(chunks->\@chunks)
Function: Creates a new ChunkedSource object from an array
Returns : A Text::Same::FileChunkedSource object
Args : chunks - an array of strings
name
Title : name
Usage : my $name = $source->name();
Function: return the name of this source - generally the filename
get_all_chunks
Title : get_all_chunks
Usage : $all_chunks = $source->get_all_chunks;
Function: return (in order) the chunks from this source
get_chunk_by_indx
Title : get_chunk_by_indx
Usage : $chunk = $source->get_chunk_by_indx($indx);
Function: return the chunk/line at the given index in this source
get_all_chunks_count
Title : get_all_chunks_count
Usage : $count = $source->get_all_chunks_count;
Function: return the number of chunks in this source
get_filtered_chunk_indexes
Title : get_filtered_chunk_indexes
Usage : $filtered_chunk_indexes = $source->get_filtered_chunk_indexes($options);
Function: return (in order) the chunks from this source that match the given
options:
ignore_case=> (0 or 1) -- ignore case when comparing
ignore_blanks=> (0 or 1) -- ignore blank lines when comparing
ignore_space=> (0 or 1) -- ignore whitespace in chunks
get_matching_chunk_indexes
Title : get_matching_chunk_indexes
Usage : $matches = $source->get_matching_chunk_indexes($options, $text);
Function: return (in order) the chunks from this source that match the given
text.
options:
ignore_case=> (0 or 1) -- ignore case when comparing
ignore_blanks=> (0 or 1) -- ignore blank lines when comparing
ignore_space=> (0 or 1) -- ignore whitespace in chunks
_get_filtered_indx_from_real
Title : _get_filtered_indx_from_real
Usage : $indx = $source->_get_filtered_indx_from_real($options, $real_indx);
Function: for the given index (eg. line number) in this source, return the
corresponding index in the list of chunks generated by applying the
$options. For example if $options->{ignore_blanks} is true the
filtered chunks will contain no blank lines.
eg. input lines:
some text on line 0
<blank line>
<blank line>
some text on line 3
the real index of "some text on line 3" is 3, but the filtered index is 1 if
ignore_blanks is set because the filtered lines are:
some text on line 0
some text on line 3
get_previous_chunk_indx
Title : get_previous_chunk_indx
Usage : $prev_chunk_indx =
$source->get_previous_chunk_indx($options, $chunk_indx);
Function: return the previous chunk index from the list of filtered chunk
indexes (for the given $options). See discussion above.
get_next_chunk_indx
Title : get_next_chunk_indx
Usage : $next_chunk_indx =
$source->get_next_chunk_indx($options, $chunk_indx);
Function: return the next chunk index from the list of filtered chunk
indexes (for the given $options). See discussion above.
