Class POJONode

    • Constructor Detail

      • POJONode

        public POJONode​(java.lang.Object v)

    • 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 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 interface TreeNode
        Specified by:
        asToken in class ValueNode
        Returns:
        JsonToken that is most closely associated with the node type

      • binaryValue

        public byte[] binaryValue()
                   throws java.io.IOException
        As it is possible that some implementations embed byte[] as POJONode (despite optimal being BinaryNode), let's add support for exposing binary data here too.
        Overrides:
        binaryValue in class JsonNode
        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 a 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

      • asText

        public java.lang.String asText​(java.lang.String defaultValue)
        Description copied from class: JsonNode
        Method similar to JsonNode.asText(), except that it will return defaultValue in cases where null value would be returned; either for missing nodes (trying to access missing property, or element at invalid item for array) or explicit nulls.
        Overrides:
        asText in class JsonNode

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

        Overrides:
        asBoolean 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 cannot 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 cannot be converted to a 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 cannot 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

      • 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.

        Specified by:
        equals in class JsonNode
