IntIntHashMap

com.netflix.atlas.core.util.IntIntHashMap
class IntIntHashMap(noData: Int, capacity: Int)

Mutable integer map based on open-addressing. Primary use-case is computing a count for the number of times a particular value was encountered.

Value parameters

capacity

Initial capacity guideline. The actual size of the underlying buffer will be the next prime >= capacity. Default is 10.

noData

Value to use to represent no data in the array. This value should not be used in the input.

Concrete methods

def foreach(f: (Int, Int) => Unit): Unit

Execute f for each item in the set.

Execute f for each item in the set.

Attributes

def get(k: Int, dflt: Int): Int

Get the value associated with key, k. If no value is present, then the dflt value will be returned.

Get the value associated with key, k. If no value is present, then the dflt value will be returned.

Attributes

def increment(k: Int): Unit

Add one to the count associated with k. If the key is not already in the map a new entry will be created with a count of 1.

Add one to the count associated with k. If the key is not already in the map a new entry will be created with a count of 1.

Attributes

def increment(k: Int, amount: Int): Unit

Add amount to the count associated with k. If the key is not already in the map a new entry will be created with a count of amount.

Add amount to the count associated with k. If the key is not already in the map a new entry will be created with a count of amount.

Attributes

def put(k: Int, v: Int): Unit

Put an integer key/value pair into the map. The key, k, should not be equivalent to the noData value used for this map. If an entry with the same key already exists, then the value will be overwritten.

Attributes

def size: Int

Return the number of items in the set. This is a constant time operation.
