public Class UnmodifiableHeaders

Overrides com.sun.net.httpserver.Headers.add.

Doc from com.sun.net.httpserver.Headers.add.

Adds the given value to the list of headers for the given key. If the mapping does not already exist, then it is created.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.clear.

Implements java.util.Map.clear.

Doc from java.util.Map.clear.

Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.containsKey.

Implements java.util.Map.containsKey.

Doc from java.util.Map.containsKey.

Returns true if this map contains a mapping for the specified key. More formally, returns true if and only if this map contains a mapping for a key k such that Objects.equals(key, k). (There can be at most one such mapping.)

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.containsValue.

Implements java.util.Map.containsValue.

Doc from java.util.Map.containsValue.

Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that Objects.equals(value, v). This operation will probably require time linear in the map size for most implementations of the Map interface.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.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.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.equals.

Implements java.util.Map.equals.

Doc from java.util.Map.equals.

Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings. More formally, two maps m1 and m2 represent the same mappings if m1.entrySet().equals(m2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.get.

Implements java.util.Map.get.

Doc from java.util.Map.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.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.getFirst.

Doc from com.sun.net.httpserver.Headers.getFirst.

Returns the first value from the List of String values for the given key, or null if no mapping for the key exists.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.hashCode.

Implements java.util.Map.hashCode.

Doc from java.util.Map.hashCode.

Returns the hash code value for this map. The hash code of a map is defined to be the sum of the hash codes of each entry in the map's entrySet() view. This ensures that m1.equals(m2) implies that m1.hashCode()==m2.hashCode() for any two maps m1 and m2, as required by the general contract of Object#hashCode.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.isEmpty.

Implements java.util.Map.isEmpty.

Doc from java.util.Map.isEmpty.

Returns true if this map contains no key-value mappings.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.keySet.

Implements java.util.Map.keySet.

Doc from java.util.Map.keySet.

Returns a Set view of the keys 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), 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.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.put.

Implements java.util.Map.put.

Doc from java.util.Map.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.)

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.putAll.

Implements java.util.Map.putAll.

Doc from java.util.Map.putAll.

Copies all of the mappings from the specified map to this map (optional operation). The effect of this call is equivalent to that of calling put(k, v) on this map once for each mapping from key k to value v in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress. If the specified map has a defined encounter order, processing of its mappings generally occurs in that order.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.remove.

Implements java.util.Map.remove.

Doc from java.util.Map.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.

Annotations

@Override

Overrides default java.util.Map.replace.

Doc from java.util.Map.replace.

Replaces the entry for the specified key only if it is currently mapped to some value (optional operation).

Annotations

@Override

Overrides default java.util.Map.replace.

Doc from java.util.Map.replace.

Replaces the entry for the specified key only if currently mapped to the specified value (optional operation).

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.replaceAll.

Overrides default java.util.Map.replaceAll.

Doc from java.util.Map.replaceAll.

Replaces each entry's value with the result of invoking the given function on that entry until all entries have been processed or the function throws an exception (optional operation). Exceptions thrown by the function are relayed to the caller.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.set.

Doc from com.sun.net.httpserver.Headers.set.

Sets the given value as the sole header value for the given key. If the mapping does not already exist, then it is created.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.size.

Implements java.util.Map.size.

Doc from java.util.Map.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.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

Annotations

@Override

Overrides com.sun.net.httpserver.Headers.values.

Implements java.util.Map.values.

Doc from java.util.Map.values.

Returns a Collection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Collection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
