Class UnifiedMapWithHashingStrategy<K,V>

java.lang.Object

org.eclipse.collections.impl.AbstractRichIterable<V>

All Implemented Interfaces:

Externalizable, Serializable, Cloneable, Iterable<V>, Map<K,V>, org.eclipse.collections.api.InternalIterable<V>, org.eclipse.collections.api.map.MapIterable<K,V>, org.eclipse.collections.api.map.MutableMap<K,V>, org.eclipse.collections.api.map.MutableMapIterable<K,V>, org.eclipse.collections.api.map.UnsortedMapIterable<K,V>, org.eclipse.collections.api.RichIterable<V>, BatchIterable<V>

@NotThreadSafe
public class UnifiedMapWithHashingStrategy<K,V>
extends AbstractMutableMap<K,V>
implements Externalizable, BatchIterable<V>

UnifiedMapWithHashingStrategy stores key/value pairs in a single array, where alternate slots are keys and values. This is nicer to CPU caches as consecutive memory addresses are very cheap to access. Entry objects are not stored in the table like in java.util.HashMap. Instead of trying to deal with collisions in the main array using Entry objects, we put a special object in the key slot and put a regular Object[] in the value slot. The array contains the key value pairs in consecutive slots, just like the main array, but it's a linear list with no hashing.

The difference between UnifiedMap and UnifiedMapWithHashingStrategy is that a HashingStrategy based UnifiedMap does not rely on the hashCode or equality of the object at the key, but instead relies on a HashingStrategy implementation provided by a developer to compute the hashCode and equals for the objects stored in the map.

getCollidingBuckets

public int getCollidingBuckets()

getMapMemoryUsedInWords

public int getMapMemoryUsedInWords()

Returns the number of JVM words that is used by this map. A word is 4 bytes in a 32bit VM and 8 bytes in a 64bit VM. Each array has a 2 word header, thus the formula is: words = (internal table length + 2) + sum (for all chains (chain length + 2))

Returns:

the number of JVM words that is used by this map.

toString

public String toString()

Description copied from class: AbstractRichIterable

Returns a string representation of this collection. The string representation consists of a list of the collection's elements in the order they are returned by its iterator, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ", " (comma and space). Elements are converted to strings as by String.valueOf(Object).

This implementation creates an empty string buffer, appends a left square bracket, and iterates over the collection appending the string representation of each element in turn. After appending each element except the last, the string ", " is appended. Finally a right bracket is appended. A string is obtained from the string buffer, and returned.

toString in interface org.eclipse.collections.api.map.MapIterable<K,V>

toString in interface org.eclipse.collections.api.RichIterable<V>

Overrides:

toString in class AbstractRichIterable<V>

Returns:

a string representation of this collection.
