Method Detail
-
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 firstJsonToken
that equivalent stream event would produce (for most nodes there is just one token but for structured/container types multiple)
-
isPojo
public boolean isPojo()
Description copied from class:JsonNode
Method that can be used to check if the node is a wrapper for a POJO ("Plain Old Java Object" aka "bean". Returns true only for instances ofPOJONode
.
-
getBinaryValue
public byte[] getBinaryValue() throws java.io.IOException
Description copied from class:JsonNode
Method to use for accessing binary content of binary nodes (nodes for whichJsonNode.isBinary()
returns true); or for Text Nodes (ones for whichJsonNode.getTextValue()
returns non-null value), to read decoded base64 data. For other types of nodes, returns null.- Overrides:
getBinaryValue
in classJsonNode
- Returns:
- Binary data this node contains, iff it is a binary node; null otherwise
- Throws:
java.io.IOException
-
asText
public java.lang.String 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(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 java.io.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:
java.io.IOException
JsonProcessingException
-
getPojo
public java.lang.Object getPojo()
Method that can be used to access the POJO this node wraps.
-
equals
public boolean equals(java.lang.Object o)
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

hashCode
public int hashCode()
