public enum StreamReadCapability extends Enum<StreamReadCapability> implements JacksonFeature
JsonParser
for given format
(or in case of buffering, original format) has.
Used in some cases to adjust aspects of things like content conversions,
coercions and validation by format-agnostic functionality.
Specific or expected usage documented by individual capability entry
Javadocs.Enum Constant and Description |
---|
DUPLICATE_PROPERTIES
Capability that indicates that data format can expose multiple properties
with same name ("duplicates") within one Object context.
|
SCALARS_AS_OBJECTS
Capability that indicates that data format may in some cases expose Scalar values
(whether typed or untyped) as Object values.
|
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. |
Modifier and Type | Method and Description |
---|---|
boolean |
enabledByDefault()
Accessor for checking whether this feature is enabled by default.
|
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 StreamReadCapability |
valueOf(String name)
Returns the enum constant of this type with the specified name.
|
static StreamReadCapability[] |
values()
Returns an array containing the constants of this enum type, in
the order they are declared.

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 is currently only enabled for XML format backend.

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.
