Class GenericData

java.lang.Object
  java.util.AbstractMap<String,Object>
      com.google.api.client.util.GenericData

All Implemented Interfaces:

Cloneable, Map<String,Object>

Direct Known Subclasses:

GenericJson, GenericUrl, GenericXml, HttpHeaders, JsonHttpRequest, JsonRpcRequest

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.

Constructor Detail

GenericData

public GenericData()

Constructs with case-insensitive keys.

GenericData

public GenericData(EnumSet<GenericData.Flags> flags)

Parameters:

flags - flags that impact behavior of generic data

Method Detail

get

public final Object get(Object name)

Specified by:

get in interface Map<String,Object>

Overrides:

get in class AbstractMap<String,Object>

put

public final Object put(String fieldName,
                        Object value)

Specified by:

put in interface Map<String,Object>

Overrides:

put in class AbstractMap<String,Object>

set

public final void 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.

putAll

public final void putAll(Map<? extends String,?> map)

Specified by:

putAll in interface Map<String,Object>

Overrides:

putAll in class AbstractMap<String,Object>

remove

public final Object remove(Object name)

Specified by:

remove in interface Map<String,Object>

Overrides:

remove in class AbstractMap<String,Object>

entrySet

public Set<Map.Entry<String,Object>> entrySet()

Specified by:

entrySet in interface Map<String,Object>

Specified by:

entrySet in class AbstractMap<String,Object>

clone

public GenericData clone()

Makes a "deep" clone of the generic data, in which the clone is completely independent of the original.

Overrides:

clone in class AbstractMap<String,Object>

getUnknownKeys

public final Map<String,Object> getUnknownKeys()

Returns the map of unknown data key name to value.

Since:

1.5

setUnknownKeys

public final void setUnknownKeys(Map<String,Object> unknownFields)

Sets the map of unknown data key name to value.

Since:

1.5

Returns the class information.

Since:

1.10
