JsonArray (Hazelcast Root 3.12.6 API)

java.lang.Object
- com.hazelcast.internal.json.JsonValue
- - com.hazelcast.internal.json.JsonArray

All Implemented Interfaces:

Serializable, Iterable<JsonValue>
```
public class JsonArray
extends JsonValue
implements Iterable<JsonValue>
```
Represents a JSON array, an ordered collection of JSON values.
Elements can be added using the add(...) methods which accept instances of JsonValue, strings, primitive numbers, and boolean values. To replace an element of an array, use the set(int, ...) methods.

Elements can be accessed by their index using get(int). This class also supports iterating over the elements in document order using an iterator() or an enhanced for loop:
```
 for (JsonValue value : jsonArray) {
   ...
 }
 
```
An equivalent List can be obtained from the method values().

Note that this class is not thread-safe. If multiple threads access a JsonArray instance concurrently, while at least one of these threads modifies the contents of this array, access to the instance must be synchronized externally. Failure to do so may lead to an inconsistent state.

This class is not supposed to be extended by clients.

```
public JsonArray()
```
    Creates a new empty JsonArray.
  - JsonArray
```
public JsonArray(JsonArray array)
```
    Creates a new JsonArray with the contents of the specified JSON array.
    
    Parameters:
    
    array - the JsonArray to get the initial contents from, must not be null
- Method Detail
  - readFrom
```
@Deprecated
public static JsonArray readFrom(Reader reader)
                                      throws IOException
```
    Deprecated. Use Json.parse(Reader).asArray() instead
    
    Reads a JSON array from the given reader.
    Characters are read in chunks and buffered internally, therefore wrapping an existing reader in an additional BufferedReader does not improve reading performance.
    
    Parameters:
    
    reader - the reader to read the JSON array from
    
    Returns:
    
    the JSON array that has been read
    
    Throws:
    
    IOException - if an I/O error occurs in the reader
    
    ParseException - if the input is not valid JSON
    
    UnsupportedOperationException - if the input does not contain a JSON array
  - readFrom
```
@Deprecated
public static JsonArray readFrom(String string)
```
    Deprecated. Use Json.parse(String).asArray() instead
    
    Reads a JSON array from the given string.
    
    Parameters:
    
    string - the string that contains the JSON array
    
    Returns:
    
    the JSON array that has been read
    
    Throws:
    
    ParseException - if the input is not valid JSON
    
    UnsupportedOperationException - if the input does not contain a JSON array
  - unmodifiableArray
```
public static JsonArray unmodifiableArray(JsonArray array)
```
    Returns an unmodifiable wrapper for the specified JsonArray. This method allows to provide read-only access to a JsonArray.
    The returned JsonArray is backed by the given array and reflects subsequent changes. Attempts to modify the returned JsonArray result in an UnsupportedOperationException.
    
    Parameters:
    
    array - the JsonArray for which an unmodifiable JsonArray is to be returned
    
    Returns:
    
    an unmodifiable view of the specified JsonArray
