Class NFPropertySpec

java.lang.Object
  com.netflix.nfgraph.spec.NFPropertySpec

public class NFPropertySpec
extends java.lang.Object

This class defines a specification for a single property.

The recommended interface for creating a property is to instantiate with the flag method below.

By default, an NFPropertySpec is GLOBAL, MULTIPLE, and COMPACT.

 import static com.netflix.nfgraph.spec.NFPropertySpec.*;
 
 ...
 
 NFPropertySpec spec1 = new NFPropertySpec( "property1", "foreignNodeType1", MULTIPLE | HASH );
 NFPropertySpec spec2 = new NFPropertySpec( "property2", "foreignNodeType2", MULTIPLE | COMPACT | MODEL_SPECIFIC);
 NFPropertySpec spec3 = new NFPropertySpec( "property2", "foreignNodeType3", SINGLE );
 
 

Field Summary

static int	COMPACT A MULTIPLE property instantiated with this flag will be represented as a CompactOrdinalSet in an NFCompressedGraph.
static int	GLOBAL A property spec instantiated with this flag will not be separable into connection models.
static int	HASH A MULTIPLE property instantiated with this flag will be represented as a BitSetOrdinalSet in an NFCompressedGraph.
static int	MODEL_SPECIFIC A property spec instantiated with this flag will be separable into connection models.
static int	MULTIPLE A property spec instantiated with this flag will be allowed multiple connections.
static int	SINGLE A property spec instantiated with this flag will be allowed only a single connection.

Constructor Summary

NFPropertySpec(java.lang.String name, java.lang.String toNodeType, boolean isGlobal, boolean isMultiple, boolean isHashed)

NFPropertySpec(java.lang.String name, java.lang.String toNodeType, int flags)

Constructor Detail

NFPropertySpec

public NFPropertySpec(java.lang.String name,
                      java.lang.String toNodeType,
                      int flags)

The recommended constructor.

Parameters:

name - the name of the property.

toNodeType - the node type to which this property connects

flags - a bitwise-or of the various flags defined as constants in NFPropertySpec.
For example, a global, multiple, compact property would take the value NFPropertySpec.GLOBAL | NFPropertySpec.MULTIPLE | NFPropertySpec.COMPACT
