Method Detail

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 name

java.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 given index. The correct value for the index is highly implementation specific. The better way to initialize a cursor is through AdjacencyProperties.propertyCursor(long) or related.

Specified by:

init in interface PropertyCursor

hasNextLong

public boolean hasNextLong()

Description copied from interface: PropertyCursor

Return true iff there is at least one more target to decode.

Specified by:

hasNextLong in interface PropertyCursor

nextLong

public long nextLong()

Description copied from interface: PropertyCursor

Read the next target id. It is undefined behavior if this is called after PropertyCursor.hasNextLong() returns false.

Specified by:

nextLong in interface PropertyCursor

close

public void close()

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface PropertyCursor
