  • Constructor Details

    • V4

      public V4(int address, byte netmask)
      Canonical constructor that enforces the documented invariants.
      • netmask must be in the range 0–32 (inclusive)
      • all host bits of address beyond the netmask must be zero
      Throws:
      IllegalArgumentException - if the arguments do not satisfy the invariants

  • Method Details

    • appendInTextTo

      public void appendInTextTo(StringBuilder sb)
      Description copied from interface: Cidr
      Appends the PostgreSQL text representation of this CIDR block to sb.
      Specified by:
      appendInTextTo in interface Cidr

    • encodeInBinary

      public void encodeInBinary(ByteArrayOutputStream out)
      Description copied from interface: Cidr
      Encodes this CIDR block in PostgreSQL binary wire format into out.
      Specified by:
      encodeInBinary in interface Cidr

    • toString

      public String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with '=='.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • address

      public int address()
      Returns the value of the address record component.
      Returns:
      the value of the address record component

    • netmask

      public byte netmask()
      Returns the value of the netmask record component.
      Returns:
      the value of the netmask record component
