Class BooleanNode

java.lang.Object
  extended by org.codehaus.jackson.JsonNode
      extended by org.codehaus.jackson.node.BaseJsonNode
          extended by org.codehaus.jackson.node.ValueNode
              extended by org.codehaus.jackson.node.BooleanNode
All Implemented Interfaces:
Iterable<JsonNode>, JsonSerializable, JsonSerializableWithType

public final class BooleanNode
extends ValueNode

This concrete value class is used to contain boolean (true / false) values. Only two instances are ever created, to minimize memory usage


Field Summary
static BooleanNode FALSE
           
static BooleanNode TRUE
           
 
Method Summary
 JsonToken asToken()
          Method that can be used for efficient type detection when using stream abstraction for traversing nodes.
 boolean equals(Object o)
           Note: marked as abstract to ensure all implementation classes define it properly.
 boolean getBooleanValue()
           
static BooleanNode getFalse()
           
static BooleanNode getTrue()
           
 String getValueAsText()
          Method that will return valid String representation of the container value, if the node is a value node (method JsonNode.isValueNode() returns true), otherwise null.
 boolean isBoolean()
          Method that can be used to check if this node was created from Json boolean value (literals "true" and "false").
 void serialize(JsonGenerator jg, SerializerProvider provider)
          Method called to serialize node instances using given generator.
static BooleanNode valueOf(boolean b)

Field Detail

TRUE

public static final BooleanNode TRUE

FALSE

public static final BooleanNode FALSE
Method Detail

getTrue

public static BooleanNode getTrue()

getFalse

public static BooleanNode getFalse()

valueOf

public static BooleanNode valueOf(boolean b)

asToken

public JsonToken asToken()
Description copied from class: BaseJsonNode
Method that can be used for efficient type detection when using stream abstraction for traversing nodes. Will return the first JsonToken that equivalent stream event would produce (for most nodes there is just one token but for structured/container types multiple)

Specified by:
asToken in class ValueNode

isBoolean

public boolean isBoolean()
Description copied from class: JsonNode
Method that can be used to check if this node was created from Json boolean value (literals "true" and "false").

Overrides:
isBoolean in class JsonNode

getBooleanValue

public boolean getBooleanValue()
Overrides:
getBooleanValue in class JsonNode

getValueAsText

public String getValueAsText()
Description copied from class: JsonNode
Method that will return valid String representation of the container value, if the node is a value node (method JsonNode.isValueNode() returns true), otherwise null.

Note: to serialize nodes of any type, you should call JsonNode.toString() instead.

Specified by:
getValueAsText in class JsonNode

serialize

public final void serialize(JsonGenerator jg,
                            SerializerProvider provider)
                     throws IOException,
                            JsonProcessingException
Description copied from class: BaseJsonNode
Method called to serialize node instances using given generator.

Specified by:
serialize in interface JsonSerializable
Specified by:
serialize in class BaseJsonNode
Throws:
IOException
JsonProcessingException

equals

public boolean equals(Object o)
Description copied from class: JsonNode

Note: marked as abstract to ensure all implementation classes define it properly.

Specified by:
equals in class JsonNode
