Constructor Detail

JSONObject

public JSONObject()

Construct an empty JSONObject with a default initial capacity and load factor.

JSONObject

public JSONObject(int initialCapacity)

Construct a JSONObject with an initial capacity and default load factor.

Parameters:

initialCapacity - initial capacity of the map

JSONObject

public JSONObject(int initialCapacity,
                  float loadFactor)

Constructs a JSONObject with an initial capacity and load factor.

JSONObject

public JSONObject(java.util.Map<? extends java.lang.String,? extends java.lang.Object> map)

Construct a JSONObject from an existing map of objects.

Method Detail

put

public java.lang.Object put(java.lang.String key,
                            java.lang.Object value)
                     throws java.lang.ClassCastException

Associates the specified value with the specified key in this object.

Specified by:

put in interface java.util.Map<java.lang.String,java.lang.Object>

Overrides:

put in class java.util.HashMap<java.lang.String,java.lang.Object>

Parameters:

key - JSON object field name with which the specified value is to be associated

value - value for the JSON field

Returns:

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

Throws:

java.lang.NullPointerException - if the key is null

java.lang.ClassCastException - if the passed in value is not a suitable JSON object

putAll

public void putAll(java.util.Map<? extends java.lang.String,? extends java.lang.Object> map)
            throws java.lang.ClassCastException

Copies all of the mappings from the specified map to this map.

Specified by:

putAll in interface java.util.Map<java.lang.String,java.lang.Object>

Overrides:

putAll in class java.util.HashMap<java.lang.String,java.lang.Object>

Parameters:

map - mappings to be stored in this map

Throws:

java.lang.NullPointerException - if the specified map is null or contains null keys

java.lang.ClassCastException - if the passed in value is not a suitable JSON object
