Class InetAddressPoint

java.lang.Object

org.apache.lucene.document.Field

org.apache.lucene.document.InetAddressPoint

All Implemented Interfaces:

IndexableField

public class InetAddressPoint
extends Field

An indexed 128-bit InetAddress field.

Finding all documents within a range at search time is efficient. Multiple values for the same field in one document is allowed.

This field defines static factory methods for creating common queries:

• newExactQuery(String, InetAddress) for matching an exact network address.
• newPrefixQuery(String, InetAddress, int) for matching a network based on CIDR prefix.
• newRangeQuery(String, InetAddress, InetAddress) for matching arbitrary network address ranges.
• newSetQuery(String, InetAddress...) for matching a set of network addresses.

This field supports both IPv4 and IPv6 addresses: IPv4 addresses are converted to IPv4-Mapped IPv6 Addresses: indexing 1.2.3.4 is the same as indexing ::FFFF:1.2.3.4.

Constructor Detail

InetAddressPoint

public InetAddressPoint(String name,
                        InetAddress point)

Creates a new InetAddressPoint, indexing the provided address.

Parameters:

name - field name

point - InetAddress value

Throws:

IllegalArgumentException - if the field name or value is null.

Method Detail

nextUp

public static InetAddress nextUp(InetAddress address)

Return the InetAddress that compares immediately greater than address.

Throws:

ArithmeticException - if the provided address is the maximum ip address

nextDown

public static InetAddress nextDown(InetAddress address)

Return the InetAddress that compares immediately less than address.

Throws:

ArithmeticException - if the provided address is the minimum ip address

setInetAddressValue

public void setInetAddressValue(InetAddress value)

Change the values of this field

setBytesValue

public void setBytesValue(BytesRef bytes)

Overrides:

setBytesValue in class Field

toString

public String toString()

Overrides:

toString in class Field

encode

public static byte[] encode(InetAddress value)

Encode InetAddress value into binary encoding

decode

public static InetAddress decode(byte[] value)

Decodes InetAddress value from binary encoding

newExactQuery

public static Query newExactQuery(String field,
                                  InetAddress value)

Create a query for matching a network address.

Parameters:

field - field name. must not be null.

value - exact value

Returns:

a query matching documents with this exact value

Throws:

IllegalArgumentException - if field is null.

newPrefixQuery

public static Query newPrefixQuery(String field,
                                   InetAddress value,
                                   int prefixLength)

Create a prefix query for matching a CIDR network range.

Parameters:

field - field name. must not be null.

value - any host address

prefixLength - the network prefix length for this address. This is also known as the subnet mask in the context of IPv4 addresses.

Returns:

a query matching documents with addresses contained within this network

Throws:

IllegalArgumentException - if field is null, or prefixLength is invalid.

newRangeQuery

public static Query newRangeQuery(String field,
                                  InetAddress lowerValue,
                                  InetAddress upperValue)

Create a range query for network addresses.

You can have half-open ranges (which are in fact </≤ or >/≥ queries) by setting lowerValue = InetAddressPoint.MIN_VALUE or upperValue = InetAddressPoint.MAX_VALUE.

Ranges are inclusive. For exclusive ranges, pass InetAddressPoint#nextUp(lowerValue) or InetAddressPoint#nexDown(upperValue).

Parameters:

field - field name. must not be null.

lowerValue - lower portion of the range (inclusive). must not be null.

upperValue - upper portion of the range (inclusive). must not be null.

Returns:

a query matching documents within this range.

Throws:

IllegalArgumentException - if field is null, lowerValue is null, or upperValue is null

newSetQuery

public static Query newSetQuery(String field,
                                InetAddress... values)

Create a query matching any of the specified 1D values. This is the points equivalent of TermsQuery.

Parameters:

field - field name. must not be null.

values - all values to match
