Class SimpleIntEncodedValue

java.lang.Object

com.graphhopper.routing.profiles.SimpleIntEncodedValue

All Implemented Interfaces:

EncodedValue, IntEncodedValue

Direct Known Subclasses:

EnumEncodedValue, FactorizedDecimalEncodedValue, MappedDecimalEncodedValue, SimpleBooleanEncodedValue

public class SimpleIntEncodedValue
extends Object
implements IntEncodedValue

Implementation of the IntEncodedValue via a limited number of bits. It introduces simple handling of "backward"- and "forward"-edge information.

Field Summary

Fields

Modifier and Type	Field and Description
protected int	bwdDataIndex
protected int	fwdDataIndex There are multiple int values possible per edge.

Constructor Summary

Constructors

Constructor and Description
SimpleIntEncodedValue(String name, int bits)
SimpleIntEncodedValue(String name, int bits, boolean storeBothDirections) This constructor reserves the specified number of bits in the underlying data structure or twice the amount if store2DirectedValues is true.

Method Summary

Modifier and Type	Method and Description
boolean	equals(Object o)
int	getInt(boolean reverse, IntsRef ref) This method restores the integer value from the specified 'flags' taken from the storage.
String	getName() This method returns the hierarchical name like vehicle.type of this EncodedValue
int	hashCode()
int	init(EncodedValue.InitializerConfig init) This method sets the dataIndex and shift of this EncodedValue object and potentially changes the submitted init object afterwards via calling next
void	setInt(boolean reverse, IntsRef ref, int value) This method stores the specified integer value in the specified IntsRef.

There are multiple int values possible per edge. Here we specify the index into this integer array.

bwdDataIndex

protected int bwdDataIndex

Constructor Detail

SimpleIntEncodedValue

public SimpleIntEncodedValue(String name,
                             int bits)

SimpleIntEncodedValue

public SimpleIntEncodedValue(String name,
                             int bits,
                             boolean storeBothDirections)

This constructor reserves the specified number of bits in the underlying data structure or twice the amount if store2DirectedValues is true.

Parameters:

storeBothDirections - if true the encoded value can be different for the forward and backward direction of an edge.

Method Detail

init

public final int init(EncodedValue.InitializerConfig init)

Description copied from interface: EncodedValue

This method sets the dataIndex and shift of this EncodedValue object and potentially changes the submitted init object afterwards via calling next

Specified by:

init in interface EncodedValue

Returns:

used bits
