values
public static PropertyCursor.EmptyPropertyCursor[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (PropertyCursor.EmptyPropertyCursor c : PropertyCursor.EmptyPropertyCursor.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static PropertyCursor.EmptyPropertyCursor valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
-
init
public void init(long index, int degree)
Description copied from interface:PropertyCursor
Initialize this cursor to point to the givenindex
. The correct value for the index is highly implementation specific. The better way to initialize a cursor is throughAdjacencyProperties.propertyCursor(long)
or related.- Specified by:

hasNextLong
public boolean hasNextLong()
Description copied from interface:PropertyCursor
Return true iff there is at least one more target to decode.- Specified by:

public long nextLong()
Description copied from interface:PropertyCursor
Read the next target id. It is undefined behavior if this is called afterPropertyCursor.hasNextLong()
returnsfalse
