Method Details

getName

public String getName()

Extractor interface: getName

Returns:

extractor name

createPatternManager

protected RegexPatternManager createPatternManager(InputStream s,
 String n)
                                            throws IOException

Description copied from class: AbstractFlexPat

Create a pattern manager given the input stream and the file name.

Specified by:

createPatternManager in class AbstractFlexPat

Parameters:

s - stream of patterns config file

n - app name

Returns:

the regex pattern manager

Throws:

IOException - Signals that an I/O exception has occurred.

extract

public List<TextMatch> extract(TextInput input)

Support the standard Extractor interface. This provides access to the most common extraction; For PoLi extraction, you would process ALL patterns in your configuration file, or if you enable only certain patterns -- those enabled at the time of this call would be executed. extract_patterns( family = null ) implies ALL patterns.

Parameters:

input - text input

Returns:

the list of TextMatch

extract

public List<TextMatch> extract(TextInput input,
 String family)

extract

public List<TextMatch> extract(String input_buf)

Description copied from interface: Extractor

Useful for working with text buffers adhoc. Fewer assumptions about input data here.

Parameters:

input_buf - text input, as a string

Returns:

the list of TextMatch

extract_patterns

public TextMatchResult extract_patterns(String text,
 String text_id,
 String family)

Extract patterns of a certain family from a block of text.

Parameters:

text - - data to process

text_id - - identifier for the data

family - - optional filter; to reuse the same PatManager but extract certain patterns only.

Returns:

PoliResult
