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.

    Modifier and Type
    Method
    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.

  • Method Details

    • 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
