    • Method Detail

      • getPersistableStandardProperties

        public Properties getPersistableStandardProperties()
        Get the standard properties in persistable form
        Returns:
        the standard core properties in persistable form

      • getPersistableUserProperties

        public Properties getPersistableUserProperties()
        Get user-defined core properties in persistable form
        Returns:
        user-defined core properties in persistable form

      • loadExtraProperties

        protected void loadExtraProperties()
        Load properties specified in an external properties file. The file to load can be specified in a properties property on the original Properties object used to create this CoreDescriptor. If this has not been set, then we look for conf/solrcore.properties underneath the instance dir. File paths are taken as read from the core's instance directory if they are not absolute.

      • buildSubstitutableProperties

        protected void buildSubstitutableProperties()
        Create the properties object used by resource loaders, etc, for property substitution. The default solr properties are prefixed with 'solr.core.', so, e.g., 'name' becomes 'solr.core.name'

      • isUserDefinedProperty

        protected static boolean isUserDefinedProperty​(String propName)
        Is this property a Solr-standard property, or is it an extra property defined per-core by the user?
        Parameters:
        propName - the Property name
        Returns:
        true if this property is user-defined

      • checkPropertyIsNotEmpty

        public static String checkPropertyIsNotEmpty​(String value,
                                             String propName)
