Enum SparseBitSet.Statistics

java.lang.Object

java.lang.Enum<SparseBitSet.Statistics>

com.zaxxer.sparsebits.SparseBitSet.Statistics

All Implemented Interfaces:

Serializable, Comparable<SparseBitSet.Statistics>

Enclosing class:

SparseBitSet

public static enum SparseBitSet.Statistics
extends Enum<SparseBitSet.Statistics>

These enumeration values are used as labels for the values in the String created by the statistics() method. The values of the corresponding statistics are ints, except for the loadFactor and Average_chain_length values, which are floats.

An array of Strings may be obtained containing a representation of each of these values. An element of such an array, say, values, may be accessed, for example, by:

      values[SparseBitSet.statistics.Buckets_available.ordinal()]

SparseBitSet.statistics(String[])

Level2_area_length The length of the level2 areas.
Level2_areas The number of level2 areas.
Level3_block_length The length of the level3 blocks.
Level3_blocks The total number of level3 blocks in use.
Set_array_length The length of the bit set array.
Set_array_max_length The maximum permitted length of the bit set array.
Size The size of the bit set, as give by the size() method.
Total_words The total number of non-zero 64-bits "words" being used to hold the representation of the bit set.

Method Detail

values

public static SparseBitSet.Statistics[] 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 (SparseBitSet.Statistics c : SparseBitSet.Statistics.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SparseBitSet.Statistics valueOf(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
