Package org.apache.sis.metadata.iso.identification

Class DefaultKeywords

  • All Implemented Interfaces:
    Serializable, Emptiable, Lenient­Comparable, Identified­Object, Keywords
    public class DefaultKeywords
extends ISOMetadata
implements Keywords
    Keywords, their type and reference source. The following property is mandatory in a well-formed metadata according ISO 19115:
    MD_Keywords   └─keyword…… Commonly used word(s) or formalised word(s) or phrase(s) used to describe the subject.

    Limitations:

    • Instances of this class are not synchronized for multi-threading. Synchronization, if needed, is caller's responsibility.
    • Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases. Serialization support is appropriate for short term storage or RMI between applications running the same version of Apache SIS. For long term storage, use XML instead.

    • Constructor Detail

      • DefaultKeywords

        public DefaultKeywords()
        Constructs an initially empty keywords.

      • DefaultKeywords

        public DefaultKeywords​(CharSequence... keywords)
        Creates keywords initialized to the given key word.
        Parameters:
        keywords - commonly used words or formalised words or phrases used to describe the subject, or null if none.

      • DefaultKeywords

        public DefaultKeywords​(Keywords object)
        Constructs a new instance initialized with the values from the specified metadata object. This is a shallow copy constructor, since the other metadata contained in the given object are not recursively copied.
        Parameters:
        object - the metadata to copy values from, or null if none.

    • Method Detail

      • castOrCopy

        public static DefaultKeywords castOrCopy​(Keywords object)
        Returns a SIS metadata implementation with the values of the given arbitrary implementation. This method performs the first applicable action in the following choices:
        • If the given object is null, then this method returns null.
        • Otherwise if the given object is already an instance of Default­Keywords, then it is returned unchanged.
        • Otherwise a new Default­Keywords instance is created using the copy constructor and returned. Note that this is a shallow copy operation, since the other metadata contained in the given object are not recursively copied.
        Parameters:
        object - the object to get as a SIS implementation, or null if none.
        Returns:
        a SIS implementation containing the values of the given object (may be the given object itself), or null if the argument was null.

      • getKeywords

        public Collection<InternationalString> getKeywords()
        Returns commonly used word(s) or formalised word(s) or phrase(s) used to describe the subject.
        Specified by:
        get­Keywords in interface Keywords
        Returns:

      • setKeywords

        public void setKeywords​(Collection<? extends InternationalString> newValues)
        Sets commonly used word(s) or formalised word(s) or phrase(s) used to describe the subject.
        Parameters:
        new­Values - the new keywords.

      • getType

        public KeywordType getType()
        Returns the subject matter used to group similar keywords.
        Specified by:
        get­Type in interface Keywords
        Returns:
        subject matter used to group similar keywords, or null.

      • setType

        public void setType​(KeywordType newValue)
        Sets the subject matter used to group similar keywords.
        Parameters:
        new­Value - the new keyword type.

      • getThesaurusName

        public Citation getThesaurusName()
        Returns the name of the formally registered thesaurus or a similar authoritative source of keywords.
        Specified by:
        get­Thesaurus­Name in interface Keywords
        Returns:
        name of registered thesaurus or similar authoritative source of keywords, or null.

      • setThesaurusName

        public void setThesaurusName​(Citation newValue)
        Sets the name of the formally registered thesaurus or a similar authoritative source of keywords.
        Parameters:
        new­Value - the new thesaurus name.

      • getKeywordClass

        @UML(identifier="keywordClass",
     obligation=OPTIONAL,
     specification=ISO_19115)
public DefaultKeywordClass getKeywordClass()
        Returns the user-defined categorization of groups of keywords that extend or are orthogonal to the standardized keyword type codes.
        Upcoming API change — generalization
        The element type will be changed to the Keyword­Class interface when GeoAPI will provide it (tentatively in GeoAPI 3.1).
        Returns:
        user-defined categorization of groups of keywords, or null if none.

        Sets the user-defined categorization of groups of keywords.
        Upcoming API change — generalization
        The argument type will be changed to the Keyword­Class interface when GeoAPI will provide it (tentatively in GeoAPI 3.1).
        Parameters:
