MultiWordEP

public MultiWordEP()

Method Detail

knownTypes

public List<String> knownTypes()

Description copied from class: ExpansionPattern

Returns the types known by this ExpansionPattern. These are possible values of the type attribute to the say-as element, as defined in MaryXML.dtd. Each subclass needs to override this to return something meaningful.

Specified by:

knownTypes in class ExpansionPattern

Returns:

known types

reMatchingChars

public Pattern reMatchingChars()

Description copied from class: ExpansionPattern

Returns the regular expression object matching any of the chars occurring in the pattern. Each subclass needs to override this to return something meaningful.

Specified by:

reMatchingChars in class ExpansionPattern

Returns:

reMatchingChars

isCandidate

protected boolean isCandidate(Element t)

Overrides:

isCandidate in class ExpansionPattern

canDealWith

protected int canDealWith(String s,
              int type)

Description copied from class: ExpansionPattern

Decide whether we can expand a string according to type typeCode. This is important in cases where a particular expansion is requested via a say-as element. As a default, reply that a string can be expanded if it would be matched by the pattern recogniser. Subclasses may wish to override this with less strict requirements. Returns the type as which it can be expanded, or -1 if expansion is not possible.

Specified by:

canDealWith in class ExpansionPattern

Parameters:

s - input

type - typeCode

Returns:

true if it can deal with input and typecode

match

protected int match(String s,
        int type)

Description copied from class: ExpansionPattern

Subclasses do their matching in this class.

Specified by:

match in class ExpansionPattern

Parameters:

s - is the String to be matched,

type - is the index in knownTypes to match with.

Returns:

type actually matched on successful match with this type (if typeCode is a general type ( typeCode == 0), it may have matched with a more specific subtype). On failure, -1 is returned.

expand

protected List<Element> expand(List<Element> tokens,
                   String s,
                   int type)

Expand multiwords and eventually replace them with mtu structures.

Specified by:

expand in class ExpansionPattern

Parameters:

tokens - tokens

s - s

type - type

Returns:

expanded
