Class NullNode

    • Field Detail

      • instance

        public static final NullNode instance
    • Method Detail

      • getInstance

        public static NullNode getInstance()
      • 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
      • isNull

        public boolean isNull()
        Description copied from class: JsonNode
        Method that can be used to check if this node was created from Json liternal null value.
        Overrides:
        isNull in class JsonNode
      • 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 (method JsonNode.isValueNode() returns true), otherwise empty String.
        Specified by:
        asText in class JsonNode
      • 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.

        Overrides:
        asInt in class JsonNode
      • 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.

        Overrides:
        asLong in class JsonNode
      • 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.

        Overrides:
        asDouble in class JsonNode
      • 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.

        Specified by:
        equals in class JsonNode
