Enum StreamReadCapability

    • Enum Constant Detail


        public static final StreamReadCapability DUPLICATE_PROPERTIES
        Capability that indicates that data format can expose multiple properties with same name ("duplicates") within one Object context. This is usually not enabled, except for formats like xml that have content model that does not map cleanly to JSON-based token stream.

        Capability may be used for allowing secondary mapping of such duplicates in case of using Tree Model (see TreeNode), or "untyped" databinding (mapping content as generic Object).

        Capability is currently only enabled for XML format backend.


        public static final StreamReadCapability SCALARS_AS_OBJECTS
        Capability that indicates that data format may in some cases expose Scalar values (whether typed or untyped) as Object values. There are additional access methods at databind level: this capability may be used to decide whether to attempt to use such methods especially in potentially ambiguous cases.

        Capability is currently only enabled for XML format backend.


        public static final StreamReadCapability UNTYPED_SCALARS
        Capability that indicates that data format only exposed "untyped" scalars: that is, instead of Number, Boolean and String types all scalar values are reported as text (JsonToken.VALUE_STRING) unless some sort of coercion is implied by caller.

        This capability is true for many textual formats like CSV, Properties and XML.

    • Method Detail

      • values

        public static StreamReadCapability[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (StreamReadCapability c : StreamReadCapability.values())
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static StreamReadCapability valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        name - the name of the enum constant to be returned.
        the enum constant with the specified name
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
      • enabledByDefault

        public boolean enabledByDefault()
        Description copied from interface: JacksonFeature
        Accessor for checking whether this feature is enabled by default.
        Specified by:
        enabledByDefault in interface JacksonFeature
        Whether this instance is enabled by default or not
      • enabledIn

        public boolean enabledIn​(int flags)
        Description copied from interface: JacksonFeature
        Convenience method for checking whether feature is enabled in given bitmask.
        Specified by:
        enabledIn in interface JacksonFeature
        flags - Bit field that contains a set of enabled features of this type
        True if this feature is enabled in passed bit field
      • getMask

        public int getMask()
        Description copied from interface: JacksonFeature
        Returns bit mask for this feature instance; must be a single bit, that is of form 1 << N.
        Specified by:
        getMask in interface JacksonFeature
        Bit mask of this feature
