# Class AncoraSpanishHeadRules

java.lang.Object
opennlp.tools.parser.lang.es.AncoraSpanishHeadRules

All Implemented Interfaces:
  `GapLabeler`, `HeadRules`, `SerializableArtifact`

public class AncoraSpanishHeadRules extends Object implements HeadRules, GapLabeler, SerializableArtifact
Class for storing the Ancora Spanish head rules associated with parsing. In this class headrules for noun phrases are specified. The rest of the rules are in opennlp-tools/lang/es/parser/es-head-rules

NOTE: This class has been adapted from opennlp.tools.parser.lang.en.HeadRules

The main change is the constituents search direction in the first for loop.

Note also the change in the return of the getHead() method: In the lang.en.HeadRules class: return constituents[ci].getHead(); Now: return constituents[ci];

Other changes include removal of deprecated methods.

- ## Constructor Details

  - ### AncoraSpanishHeadRules

    public AncoraSpanishHeadRules(Reader rulesReader) throws IOException
    Creates a new set of head rules based on the specified reader.
    Parameters:
      `rulesReader` - A `Reader` for a head rules file.
    Throws:
      `IOException` - Thrown f the head rules reader can not be read.

- ## Method Details

  - ### getPunctuationTags

    public Set<String> getPunctuationTags()
    Specified by:
      `getPunctuationTags` in interface `HeadRules`
    Returns:
      Retrieves the set of punctuation tags. Attachment decisions for these tags will not be modeled.

  - ### getHead

    public Parse getHead(Parse[] constituents, String type)
    Description copied from interface: `HeadRules`
    Retrieves the head `constituent` for the specified constituents of given `type`.
    Specified by:
      `getHead` in interface `HeadRules`
    Parameters:
      `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`.
    Returns:
      The `constituent` which represents the head.

  - ### labelGaps

    public void labelGaps(Stack<Constituent> stack)
    Description copied from interface: `GapLabeler`
    Labels `constituents` found in the `stack` with gap labels if appropriate.
    Specified by:
      `labelGaps` in interface `GapLabeler`
    Parameters:
      `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.

    Parameters:
      `writer` - The `Writer` to write the head rules to.
    Throws:
      `IOException` - Thrown if IO errors occurred during write operation.

  - ### hashCode

    public int hashCode()
    Overrides:
      `hashCode` in class `Object`

  - ### equals

    public boolean equals(Object obj)
    Overrides:
      `equals` in class `Object`

  - ### getArtifactSerializerClass

    public Class<?> getArtifactSerializerClass()
    Description copied from interface: `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.

    Specified by:
      `getArtifactSerializerClass` in interface `SerializableArtifact`
    Returns:
      The corresponding `ArtifactSerializer` class.
