public Class TextNode

Overrides com.fasterxml.jackson.databind.JsonNode.asBoolean.

Doc from com.fasterxml.jackson.databind.JsonNode.asBoolean.

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 cannot be converted to a boolean value (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

@Override

Overrides com.fasterxml.jackson.databind.JsonNode.asDouble.

Doc from com.fasterxml.jackson.databind.JsonNode.asDouble.

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 cannot be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

@Override

Overrides com.fasterxml.jackson.databind.JsonNode.asInt.

Doc from com.fasterxml.jackson.databind.JsonNode.asInt.

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 cannot be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

@Override

Overrides com.fasterxml.jackson.databind.JsonNode.asLong.

Doc from com.fasterxml.jackson.databind.JsonNode.asLong.

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 cannot be converted to a long (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

@Override

Implements abstract com.fasterxml.jackson.databind.JsonNode.asText.

Doc from com.fasterxml.jackson.databind.JsonNode.asText.

Method that will return a valid String representation of the container value, if the node is a value node (method isValueNode returns true), otherwise empty String.

Annotations

@Override

Overrides com.fasterxml.jackson.databind.JsonNode.asText.

Doc from com.fasterxml.jackson.databind.JsonNode.asText.

Returns the text value of this node or the provided defaultValue if this node does not have a text value. Useful for nodes that are MissingNode or com.fasterxml.jackson.databind.node.NullNode, ensuring a default value is returned instead of null or missing indicators.

Parameters

defaultValue:String

The default value to return if this node's text value is absent.

Returns:String

The text value of this node, or defaultValue if the text value is absent.

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.node.ValueNode.asToken.

Implements com.fasterxml.jackson.core.TreeNode.asToken.

Doc from com.fasterxml.jackson.databind.node.BaseJsonNode.asToken.

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)

Returns:JsonToken

Doc from com.fasterxml.jackson.core.TreeNode.asToken.

JsonToken that is most closely associated with the node type

@Override

Overrides com.fasterxml.jackson.databind.JsonNode.binaryValue.

Doc from com.fasterxml.jackson.databind.JsonNode.binaryValue.

Method to use for accessing binary content of binary nodes (nodes for which isBinary returns true); or for Text Nodes (ones for which textValue returns non-null value), to read decoded base64 data. For other types of nodes, returns null.

Returns:byte[]

Binary data this node contains, iff it is a binary node; null otherwise

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.JsonNode.equals.

Doc from com.fasterxml.jackson.databind.JsonNode.equals.

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.

Parameters

o:Object

Doc from java.lang.Object.equals.

the reference object with which to compare.

Returns:boolean

Doc from java.lang.Object.equals.

true if this object is the same as the obj argument; false otherwise.

Annotations

@Override

Method for accessing textual contents assuming they were base64 encoded; if so, they are decoded and resulting binary data is returned.

Annotations

@SuppressWarnings:resource

Implements abstract com.fasterxml.jackson.databind.JsonNode.getNodeType.

Doc from com.fasterxml.jackson.databind.JsonNode.getNodeType.

Return the type of this node

Returns:JsonNodeType

the node type as a JsonNodeType enum value

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.node.BaseJsonNode.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns:int

a hash code value for this object

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.node.BaseJsonNode.serialize.

Implements com.fasterxml.jackson.databind.JsonSerializable.serialize.

Doc from com.fasterxml.jackson.databind.node.BaseJsonNode.serialize.

Method called to serialize node instances using given generator.

Annotations

@Override

Overrides com.fasterxml.jackson.databind.JsonNode.textValue.

Doc from com.fasterxml.jackson.databind.JsonNode.textValue.

Method to use for accessing String values. Does NOT do any conversions for non-String value nodes; for non-String values (ones for which isTextual returns false) null will be returned. For String values, null is never returned (but empty Strings may be)

Returns:String

Textual value this node contains, iff it is a textual JSON node (comes from JSON String value entry)

Annotations

@Override

Factory method that should be used to construct instances. For some common cases, can reuse canonical instances: currently this is the case for empty Strings, in future possible for others as well. If null is passed, will return null.

Returns:TextNode

Resulting TextNode object, if v is NOT null; null if it is.
