      • checkFacetName

        public static java.lang.String checkFacetName(java.lang.String name)
        Checks whether a facet name is valid. The facet name length must be between 1 and SearchApiLimits.MAXIMUM_NAME_LENGTH inclusive, and it should match SearchApiLimits.FIELD_NAME_PATTERN.
        Parameters:
        name - the facet name to check
        Returns:
        the checked facet name
        Throws:
        java.lang.IllegalArgumentException - if the facet name is null or empty or is longer than SearchApiLimits#MAXIMUM_NAME_LENGTH or it doesn't match #FIELD_NAME_PATTERN.
      • checkFacetName

        public static java.lang.String checkFacetName(java.lang.String name,
                                                      java.lang.String callerContext)
        Checks whether a facet name is valid. The facet name length must be between 1 and SearchApiLimits.MAXIMUM_NAME_LENGTH inclusive, and it should match SearchApiLimits.FIELD_NAME_PATTERN.
        Parameters:
        name - the facet name to check
        callerContext - the caller context used for creating error message in case of a failure.
        Returns:
        the checked facet name
        Throws:
        java.lang.IllegalArgumentException - if the facet name is empty or is longer than SearchApiLimits#MAXIMUM_NAME_LENGTH or it doesn't match #FIELD_NAME_PATTERN.
      • checkAtom

        public static java.lang.String checkAtom(java.lang.String value)

        Parameters:
        value - the atom value to check
        Returns:
        the checked atom
        Throws:
