Class IPv4AddressMatchExprMacro

java.lang.Object

org.apache.druid.query.expression.IPv4AddressMatchExprMacro

All Implemented Interfaces:

ExprMacroTable.ExprMacro, NamedFunction

public class IPv4AddressMatchExprMacro
extends Object
implements ExprMacroTable.ExprMacro

 Implements an expression that checks if an IPv4 address belongs to a particular subnet.

 Expression signatures:
 - long ipv4_match(string address, string subnet)
 - long ipv4_match(long address, string subnet)

 Valid "address" argument formats are:
 - unsigned int long (e.g., 3232235521)
 - IPv4 address dotted-decimal string (e.g., "198.168.0.1")

 The argument format for the "subnet" argument should be a literal in CIDR notation
 (e.g., "198.168.0.0/16").

 If the "address" argument does not represent an IPv4 address then false is returned.
