public abstract class JsonGenerator extends Object implements Closeable, Flushable
Implementation has no fields and therefore thread-safe, but sub-classes are not necessarily thread-safe.

Modifier and Type | Method and Description |
---|---|
abstract void |
close()
Closes the serializer and the underlying output stream or writer, and releases any memory
associated with it.
|
void |
enablePrettyPrint()
Requests that the output be pretty printed (by default it is not).
|
abstract void |
flush()
Flushes any buffered content to the underlying output stream or writer.
|
abstract JsonFactory |
getFactory()
Returns the JSON factory from which this generator was created.
|
void |
serialize(Object value)
Serializes the given JSON value object, or if
value is null it does no
serialization. |
abstract void |
writeBoolean(boolean state)
Writes a literal JSON boolean value ('true' or 'false').
|
abstract void |
writeEndArray()
Writes a JSON end array character ']'.
|
abstract void |
writeEndObject()
Writes a JSON end object character '}'.
|
abstract void |
writeFieldName(String name)
Writes a JSON quoted field name.
|
abstract void |
writeNull()
Writes a literal JSON null value.
|
abstract void |
writeNumber(BigDecimal v)
Writes a JSON big decimal value.
|
abstract void |
writeNumber(BigInteger v)
Writes a JSON big integer value.
|
abstract void |
writeNumber(double v)
Writes a JSON double value.
|
abstract void |
writeNumber(float v)
Writes a JSON float value.
|
abstract void |
writeNumber(int v)
Writes a JSON int value.
|
abstract void |
writeNumber(long v)
Writes a JSON long value.
|
abstract void |
writeNumber(String encodedValue)
Writes a JSON numeric value that has already been encoded properly.
|
abstract void |
writeStartArray()
Writes a JSON start array character '['.
|
abstract void |
writeStartObject()
Writes a JSON start object character '{'.
|
abstract void |
writeString(String value)
Writes a JSON quoted string value.
