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 firstJsonToken
that equivalent stream event would produce (for most nodes there is just one token but for structured/container types multiple) -
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"). -
getBooleanValue
public boolean getBooleanValue()Description copied from class:JsonNode
Method to use for accessing JSON boolean values (value literals 'true' and 'false'). For other types, always returns false.- Overrides:
getBooleanValue
in classJsonNode
- Returns:
- Textual value this node contains, iff it is a textual json node (comes from Json String value entry)
-
asText
Description copied from class:JsonNode
Method that will return valid String representation of the container value, if the node is a value node (methodJsonNode.isValueNode()
returns true), otherwise empty String. -
asBoolean
public boolean asBoolean()Description copied from class:JsonNode
Method that will try to convert value of this node to a Java boolean. JSON booleans map naturally; integer numbers other than 0 map to true, and 0 maps to false and Strings 'true' and 'false' map to corresponding values.If representation can not be converted to a boolean value (including structured types like Objects and Arrays), default value of false will be returned; no exceptions are thrown.
-
asBoolean
public boolean asBoolean(boolean defaultValue) Description copied from class:JsonNode
Method that will try to convert value of this node to a Java boolean. JSON booleans map naturally; integer numbers other than 0 map to true, and 0 maps to false and Strings 'true' and 'false' map to corresponding values.If representation can not be converted to a boolean value (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.
-
asInt
public int asInt(int defaultValue) Description copied from class:JsonNode
Method that will try to convert value of this node to a Java int. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.If representation can not be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.
-
asLong
public long asLong(long defaultValue) Description copied from class:JsonNode
Method that will try to convert value of this node to a Java long. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.If representation can not be converted to an long (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.
-
asDouble
public double asDouble(double defaultValue) Description copied from class:JsonNode
Method that will try to convert value of this node to a Java double. Numbers are coerced using default Java rules; booleans convert to 0.0 (false) and 1.0 (true), and Strings are parsed using default Java language integer parsing rules.If representation can not be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.
-
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 interfaceJsonSerializable
- Specified by:
serialize
in classBaseJsonNode
- Throws:
IOException
JsonProcessingException
-
equals
Description copied from class:JsonNode
Equality for node objects is defined as full (deep) value equality. This means that it is possible to compare complete JSON trees for equality by comparing equality of root nodes.Note: marked as abstract to ensure all implementation classes define it properly and not rely on definition from
Object
.
