public class DefaultPrettyPrinter extends Object implements PrettyPrinter, Instantiatable<DefaultPrettyPrinter>, Serializable
PrettyPrinter
implementation that uses 2-space
indentation with platform-default linefeeds.
Usually this class is not instantiated directly, but instead
method JsonGenerator.useDefaultPrettyPrinter()
is
used, which will use an instance of this class for operation.Modifier and Type | Class and Description |
---|---|
static class |
DefaultPrettyPrinter.FixedSpaceIndenter
This is a very simple indenter that only every adds a
single space for indentation.
|
static interface |
DefaultPrettyPrinter.Indenter
Interface that defines objects that can produce indentation used
to separate object entries and array values.
|
static class |
DefaultPrettyPrinter.Lf2SpacesIndenter
Default linefeed-based indenter uses system-specific linefeeds and
2 spaces for indentation per level.
|
static class |
DefaultPrettyPrinter.NopIndenter
Dummy implementation that adds no indentation whatsoever
|
Modifier and Type | Field and Description |
---|---|
protected DefaultPrettyPrinter.Indenter |
_arrayIndenter
By default, let's use only spaces to separate array values.
|
protected int |
_nesting
Number of open levels of nesting.
|
protected DefaultPrettyPrinter.Indenter |
_objectIndenter
By default, let's use linefeed-adding indenter for separate
object entries.
|
protected SerializableString |
_rootSeparator
String printed between root-level values, if any.
|
protected boolean |
_spacesInObjectEntries
By default we will add spaces around colons used to
separate object fields and values.
|
static SerializedString |
DEFAULT_ROOT_VALUE_SEPARATOR
Constant that specifies default "root-level" separator to use between
root values: a single space character.
|
Constructor and Description |
---|
DefaultPrettyPrinter() |
DefaultPrettyPrinter(DefaultPrettyPrinter base) |
DefaultPrettyPrinter(DefaultPrettyPrinter base,
SerializableString rootSeparator) |
DefaultPrettyPrinter(SerializableString rootSeparator)
Constructor that specifies separator String to use between root values;
if null, no separator is printed.
|
DefaultPrettyPrinter(String rootSeparator)
Constructor that specifies separator String to use between root values;
if null, no separator is printed.
|
Modifier and Type | Method and Description |
---|---|
void |
beforeArrayValues(JsonGenerator jg)
Method called after array start marker has been output,
and right before the first value is to be output.
|
void |
beforeObjectEntries(JsonGenerator jg)
Method called after object start marker has been output,
and right before the field name of the first entry is
to be output.
|
DefaultPrettyPrinter |
createInstance()
Method called to ensure that we have a non-blueprint object to use;
it is either this object (if stateless), or a newly created object
with separate state.

DefaultPrettyPrinter |
withRootSeparator(SerializableString rootSeparator) |
void |
writeArrayValueSeparator(JsonGenerator jg)
Method called after an array value has been completely
output, and before another value is to be output.
|
void |
writeEndArray(JsonGenerator jg,
int nrOfValues)
Method called after an Array value has been completely output
(minus closing bracket).
|
void |
writeEndObject(JsonGenerator jg,
int nrOfEntries)
Method called after an Object value has been completely output
(minus closing curly bracket).
|
void |
writeObjectEntrySeparator(JsonGenerator jg)
Method called after an object entry (field:value) has been completely
output, and before another value is to be output.
|
void |
writeObjectFieldValueSeparator(JsonGenerator jg)
Method called after an object field has been output, but
before the value is output.
|
void |
writeRootValueSeparator(JsonGenerator jg)
Method called after a root-level value has been completely
output, and before another value is to be output.
|
void |
writeStartArray(JsonGenerator jg)
Method called when an Array value is to be output, before
any member/child values are output.
|
void |
writeStartObject(JsonGenerator jg)
Method called when an Object value is to be output, before
any fields are output.

public void writeRootValueSeparator(JsonGenerator jg) throws IOException, JsonGenerationException
PrettyPrinter
Default handling (without pretty-printing) will output a space, to allow values to be parsed correctly. Pretty-printer is to output some other suitable and nice-looking separator (tab(s), space(s), linefeed(s) or any combination thereof).
