Interface IntEncodedValue

All Superinterfaces:

EncodedValue

All Known Implementing Classes:

DecimalEncodedValueImpl, EnumEncodedValue, IntEncodedValueImpl, SimpleBooleanEncodedValue, StringEncodedValue

public interface IntEncodedValue
extends EncodedValue

This class defines how and where to store an unsigned integer. It is important to note that: 1. the range of the integer is highly limited (unlike the Java 32bit integer values) so that the storable part of it fits into the specified number of bits (maximum 32) and 2. the default value is always 0.

Method Summary

Modifier and Type	Method and Description
int	getInt(boolean reverse, int edgeId, EdgeIntAccess edgeIntAccess) This method restores the integer value from the specified 'flags' taken from the storage.
int	getMaxOrMaxStorableInt() Returns the maximum value set using this encoded value or the physical storage limit if no value has been set at all yet.
int	getMaxStorableInt() The maximum int value this EncodedValue accepts for setInt without throwing an exception.
int	getMinStorableInt() The minimum int value this EncodedValue accepts for setInt without throwing an exception.
boolean	isStoreTwoDirections()
void	setInt(boolean reverse, int edgeId, EdgeIntAccess edgeIntAccess, int value) This method stores the specified integer value in the specified IntsRef.

Method Detail

getInt

int getInt(boolean reverse,
           int edgeId,
           EdgeIntAccess edgeIntAccess)

This method restores the integer value from the specified 'flags' taken from the storage.

setInt

void setInt(boolean reverse,
            int edgeId,
            EdgeIntAccess edgeIntAccess,
            int value)

This method stores the specified integer value in the specified IntsRef.

getMaxStorableInt

int getMaxStorableInt()

The maximum int value this EncodedValue accepts for setInt without throwing an exception.

getMinStorableInt

int getMinStorableInt()

The minimum int value this EncodedValue accepts for setInt without throwing an exception.

getMaxOrMaxStorableInt

int getMaxOrMaxStorableInt()

Returns the maximum value set using this encoded value or the physical storage limit if no value has been set at all yet. Note that even when some values were set this is not equal to the global maximum across all values in the graph if values are set multiple times for the same edge and they are decreasing. However, the returned value will always be equal to or larger than the global maximum.

isStoreTwoDirections

boolean isStoreTwoDirections()

Specified by:

isStoreTwoDirections in interface EncodedValue

Returns:

true if this EncodedValue can store a different value for its reverse direction
