Enum StreamWriteCapability

  • All Implemented Interfaces:
    JacksonFeature, java.io.Serializable, java.lang.Comparable<StreamWriteCapability>

    public enum StreamWriteCapability
    extends java.lang.Enum<StreamWriteCapability>
    implements JacksonFeature
    Set of on/off capabilities that a JsonGenerator for given format (or in case of buffering, original format) has. Used in some cases to adjust aspects of things like content conversions and coercions by format-agnostic functionality. Specific or expected usage documented by individual capability entry Javadocs.
    Since:
    2.12
    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      CAN_WRITE_BINARY_NATIVELY
      Capability that indicates that the data format is able to express binary data natively, without using textual encoding like Base64.
      CAN_WRITE_FORMATTED_NUMBERS
      Capability that indicates that the data format is able to write "formatted numbers": that is, output of numbers is done as Strings and caller is allowed to pass in logical number values as Strings.

      boolean enabledIn​(int flags)
      Convenience method for checking whether feature is enabled in given bitmask.
      int getMask()
      Returns bit mask for this feature instance; must be a single bit, that is of form 1 << N.
      static StreamWriteCapability valueOf​(java.lang.String name)

      • CAN_WRITE_BINARY_NATIVELY

        public static final StreamWriteCapability CAN_WRITE_BINARY_NATIVELY
        Capability that indicates that the data format is able to express binary data natively, without using textual encoding like Base64.

        Capability is currently enabled for all binary formats and none of textual formats.

      • CAN_WRITE_FORMATTED_NUMBERS

        public static final StreamWriteCapability CAN_WRITE_FORMATTED_NUMBERS
        Capability that indicates that the data format is able to write "formatted numbers": that is, output of numbers is done as Strings and caller is allowed to pass in logical number values as Strings.

        Capability is currently enabled for most textual formats and none of binary formats.

    • Method Detail

      • values

        public static StreamWriteCapability[] 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 (StreamWriteCapability c : StreamWriteCapability.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static StreamWriteCapability valueOf​(java.lang.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.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
      • enabledByDefault

        public boolean enabledByDefault()
        Description copied from interface: JacksonFeature

        Specified by:
        enabledByDefault in interface JacksonFeature
        Returns:
        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
        Parameters:
        flags - Bit field that contains a set of enabled features of this type
        Returns:
        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
        Returns:
        Bit mask of this feature
