entrySet	back to summary
public Set<E> entrySet() Implements abstract java.util.AbstractMap.entrySet. Implements java.util.Map.entrySet. Doc from java.util.Map.entrySet. Returns a `Set` view of the mappings contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own `remove` operation, or through the `setValue` operation on a map entry returned by the iterator) the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the `Iterator.remove`, `Set.remove`, `removeAll`, `retainAll` and `clear` operations. It does not support the `add` or `addAll` operations. Returns:Set<E> a set view of the mappings contained in this map Annotations @Override

public Set<E> entrySet()

If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation, or through the setValue operation on a map entry returned by the iterator) the results of the iteration are undefined.

get back to summary

public Object get(Object key)

Overrides java.util.AbstractMap.get.

Implements java.util.Map.get.

Doc from java.util.AbstractMap.get.

Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.

More formally, if this map contains a mapping from a key k to a value v such that Objects.equals(key, k), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)

If this map permits null values, then a return value of null does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases.

Parameters

key:Object

Doc from java.util.Map.get.

the key whose associated value is to be returned

Returns:Object

Doc from java.util.Map.get.

the value to which the specified key is mapped, or null if this map contains no mapping for the key

public Object put(Object k, Object v)

Overrides java.util.AbstractMap.put.

Implements java.util.Map.put.

Doc from java.util.AbstractMap.put.

Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)

Parameters

k:Object

Doc from java.util.Map.put.

key with which the specified value is to be associated

v:Object

Doc from java.util.Map.put.

value to be associated with the specified key

Returns:Object

Doc from java.util.Map.put.

the previous value associated with key, or null if there was no mapping for key. (A null return can also indicate that the map previously associated null with key, if the implementation supports null values.)

Annotations

@Override

remove back to summary

public Object remove(Object k)

Overrides java.util.AbstractMap.remove.

Implements java.util.Map.remove.

Doc from java.util.AbstractMap.remove.

Removes the mapping for a key from this map if it is present (optional operation). More formally, if this map contains a mapping from key k to value v such that Objects.equals(key, k), that mapping is removed. (The map can contain at most one such mapping.)

Returns the value to which this map previously associated the key, or null if the map contained no mapping for the key.

If this map permits null values, then a return value of null does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to null.

The map will not contain a mapping for the specified key once the call returns.

Parameters

k:Object

Doc from java.util.Map.remove.

key whose mapping is to be removed from the map

Returns:Object

Doc from java.util.Map.remove.

the previous value associated with key, or null if there was no mapping for key.

size back to summary

public int size()

Overrides java.util.AbstractMap.size.

Implements java.util.Map.size.

Doc from java.util.AbstractMap.size.

Returns the number of key-value mappings in this map. If the map contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

Returns:int

Doc from java.util.Map.size.

the number of key-value mappings in this map
