Class TextNode

    • Constructor Detail

      • TextNode

        public TextNode​(java.lang.String v)

    • Method Detail

      • valueOf

        public static TextNode valueOf​(java.lang.String v)
        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:
        Resulting TextNode object, if v is NOT null; null if it is.

      • 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

      • textValue

        public java.lang.String textValue()
        Description copied from class: JsonNode
        Method to use for accessing String values. Does NOT do any conversions for non-String value nodes; for non-String values (ones for which JsonNode.isTextual() returns false) null will be returned. For String values, null is never returned (but empty Strings may be)
        Overrides:
        textValue in class JsonNode
        Returns:
        Textual value this node contains, iff it is a textual JSON node (comes from JSON String value entry)

      • getBinaryValue

        public byte[] getBinaryValue​(Base64Variant b64variant)
                      throws java.io.IOException
        Method for accessing textual contents assuming they were base64 encoded; if so, they are decoded and resulting binary data is returned.
        Throws:
        java.io.IOException

      • binaryValue

        public byte[] binaryValue()
                   throws java.io.IOException
        Description copied from class: JsonNode
        Method to use for accessing binary content of binary nodes (nodes for which JsonNode.isBinary() returns true); or for Text Nodes (ones for which JsonNode.textValue() returns non-null value), to read decoded base64 data. For other types of nodes, returns null.
        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
        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 NullNode, ensuring a default value is returned instead of null or missing indicators.

        NOTE: This was deprecated in 2.17.0, but as discussed through [databind#4471], was un-deprecated in 2.17.1.

        Overrides:
        asText in class JsonNode
        Parameters:
        defaultValue - The default value to return if this node's text value is absent.
        Returns:
        The text value of this node, or defaultValue if the text value is absent.

      • 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

      • 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
