    • rootNode

      public static int rootNode(String iri, int start, int end) throws com.oss.util.BadOidIriFormatException
      Helper method that parses the first node of the OID-IRI
      Parameters:
      iri - String representation of the OID-IRI
      start - offset to the start of the node
      end - end of the node
      Returns:
      numeric value corresponding to the node
      Throws:
      com.oss.util.BadOidIriFormatException - if unknown node name.

    • secondNode

      public static int secondNode(String iri, int root, int start, int end) throws com.oss.util.BadOidIriFormatException
      Helper method that parses the second node of the OID-IRI value
      Parameters:
      iri - string that contains the value of the OID-IRI
      root - value of the first (root) node of the OID-IRI value
      start - offset to the start of the node
      end - end of the node
      Returns:
      numeric value corresponding to the node
      Throws:
      com.oss.util.BadOidIriFormatException - if unknown node name.

    • checkOidIri

      public static boolean checkOidIri(String iri, boolean relative) throws com.oss.util.BadOidIriFormatException
      Parses the input string and checks that it has a valid IRI format.
      Parameters:
      iri - string value
      relative - indicates that the string represents the value of RELATIVE-OBJECT-IRI type rather than OID-IRI type
      Returns:
      true if the string has a valid IRI format.
      Throws:
      com.oss.util.BadOidIriFormatException - if the string has invalid format

    • checkRelativeOidIri

      public static boolean checkRelativeOidIri(String iri, int currentPos, int length) throws com.oss.util.BadOidIriFormatException
      Parses the input string and checks that it has a valid Relative-OID-IRI format.
      Parameters:
      iri - string value
      currentPos - offset to the start of the node
      length - length of the string
      Returns:
      true if the string has a valid Relative-OID-IRI format.
      Throws:
      com.oss.util.BadOidIriFormatException - if the string has invalid format

    • checkThirdArc

      public static boolean checkThirdArc(String iri, int currentPos, int length) throws com.oss.util.BadOidIriFormatException
      Checks that the third arc is in the range [1..26] or ['A'-'Z']
      Parameters:
      iri - string that contains the value of the OID-IRI
      currentPos - offset to the start of the node
      length - length of the string
      Returns:
      true if the arc is valid
      Throws:
      com.oss.util.BadOidIriFormatException - if unknown node name.

    • toCodePoint

      public static int toCodePoint(char high, char low)
      Converts the input high and low surrogates to the surrogate code point.
      Parameters:
      high - high surrogate character
      low - low surrogate character
      Returns:
      surrogate code point
