      public HeadRules(Reader rulesReader) throws IOException
      Creates a new set of head rules based on the specified reader.
      Parameter:
      rulesReader - A Reader for a head rules file.
      Löst aus:

  • Methodendetails

    • getPunctuationTags

      public Set<String> getPunctuationTags()
      Angegeben von:
      getPunctuationTags in Schnittstelle HeadRules
      Gibt zurück:
      Retrieves the set of punctuation tags. Attachment decisions for these tags will not be modeled.

    • getHead

      public Parse getHead(Parse[] constituents, String type)
      Beschreibung aus Schnittstelle kopiert: HeadRules
      Retrieves the head constituent for the specified constituents of given type.
      Angegeben von:
      getHead in Schnittstelle HeadRules
      Parameter:
      constituents - The constituents which make up a constituent of the specified type.
      type - The type of a constituent which is made up of the constituents.
      Gibt zurück:
      The constituent which represents the head.

    • labelGaps

      public void labelGaps(Stack<Constituent> stack)
      Beschreibung aus Schnittstelle kopiert: GapLabeler
      Labels constituents found in the stack with gap labels if appropriate.
      Angegeben von:
      labelGaps in Schnittstelle GapLabeler
      Parameter:
      stack - The Stack of un-completed constituents.

    • serialize

      public void serialize(Writer writer) throws IOException
      Serializes the head rules via a Writer in a format suitable for loading the head rules again. The encoding must be taken into account while working with the writer and reader.

      Once the entries have been written, the writer is flushed.

      Note: The writer remains open after this method returns.

      Parameter:
      writer - The Writer to write the head rules to.
      Löst aus:
      IOException - Thrown if IO errors occurred during write operation.

    • equals

      public boolean equals(Object obj)
      Setzt außer Kraft:
      equals in Klasse Object

    • getArtifactSerializerClass

      public Class<?> getArtifactSerializerClass()
      Beschreibung aus Schnittstelle kopiert: SerializableArtifact
      Retrieves the class which can serialize and recreate this artifact.

      Note: The serializer class must have a public zero argument constructor or an exception is thrown during model serialization/loading.

      Angegeben von:
      getArtifactSerializerClass in Schnittstelle SerializableArtifact
      Gibt zurück:
