public class GenericData extends AbstractMap<String,Object> implements Cloneable
Generic data that stores all unknown data key name/value pairs.
Subclasses can declare fields for known data keys using the Key annotation. Each field
can be of any visibility (private, package private, protected, or public) and must not be static.
null unknown data key names are not allowed, but null data values are allowed.
Iteration order of the data keys is based on the sorted (ascending) key names of the declared
fields, followed by the iteration order of all of the unknown data key name/value pairs.
Implementation is not thread-safe. For a thread-safe choice instead use an implementation of
ConcurrentMap.
Constructors

Methods
clone()
public GenericData clone()
Makes a "deep" clone of the generic data, in which the clone is completely independent of the
original.
entrySet()
public Set<Map.Entry<String,Object>> entrySet()
Overrides
equals(Object o)
public boolean equals(Object o)
| Parameter |
|---|
| Name | Description |
o | Object
|
Overrides
get(Object name)
public final Object get(Object name)
| Parameter |
|---|
| Name | Description |
name | Object
|
Overrides
getClassInfo()
public final ClassInfo getClassInfo()
Returns the class information.
getUnknownKeys()
public final Map<String,Object> getUnknownKeys()
Returns the map of unknown data key name to value.

put(String fieldName, Object value)
public final Object put(String fieldName, Object value)
Overrides
putAll(Map<? extends String,?> map)
public final void putAll(Map<? extends String,?> map)
| Parameter |
|---|
| Name | Description |
map | Map<? extends java.lang.String,?>
|
Overrides
remove(Object name)
public final Object remove(Object name)
| Parameter |
|---|
| Name | Description |
name | Object
|
Overrides
set(String fieldName, Object value)
public GenericData set(String fieldName, Object value)
Sets the given field value (may be null) for the given field name. Any existing value
for the field will be overwritten. It may be more slightly more efficient than #put(String, Object) because it avoids accessing the field's original value.
Overriding is only supported for the purpose of calling the super implementation and
changing the return type, but nothing else.
setUnknownKeys(Map<String,Object> unknownFields)
public final void setUnknownKeys(Map<String,Object> unknownFields)
Sets the map of unknown data key name to value.
toString()
