JsonGenerator()\n\nMethods\n-------\n\n### close()\n\n public abstract void close()\n\nCloses the serializer and the underlying output stream or writer, and releases any memory\nassociated with it.\n\n### enablePrettyPrint()\n\n public void enablePrettyPrint()\n\nRequests that the output be pretty printed (by default it is not).\n\nDefault implementation does nothing, but implementations may override to provide actual\npretty printing.\n\n### flush()\n\n public abstract void flush()\n\nFlushes any buffered content to the underlying output stream or writer.\n\n### getFactory()\n\n public abstract JsonFactory getFactory()\n\nReturns the JSON factory from which this generator was created.\n\n### serialize(Object value)\n\n public final void serialize(Object value)\n\nSerializes the given JSON value object, or if `value` is `null` it does no\nserialization.\n\n### writeBoolean(boolean state)\n\n public abstract void writeBoolean(boolean state)\n\nWrites a literal JSON boolean value ('true' or 'false').\n\n### writeEndArray()\n\n public abstract void writeEndArray()\n\nWrites a JSON end array character '\\]'.\n\n### writeEndObject()\n\n public abstract void writeEndObject()\n\nWrites a JSON end object character '}'.\n\n### writeFieldName(String name)\n\n public abstract void writeFieldName(String name)\n\nWrites a JSON quoted field name.\n\n### writeNull()\n\n public abstract void writeNull()\n\nWrites a literal JSON null value.\n\n### writeNumber(double v)\n\n public abstract void writeNumber(double v)\n\nWrites a JSON double value.\n\n### writeNumber(float v)\n\n public abstract void writeNumber(float v)\n\nWrites a JSON float value.\n\n### writeNumber(int v)\n\n public abstract void writeNumber(int v)\n\nWrites a JSON int value.\n\n### writeNumber(String encodedValue)\n\n public abstract void writeNumber(String encodedValue)\n\nWrites a JSON numeric value that has already been encoded properly.\n\n### writeNumber(BigDecimal v)\n\n public abstract void writeNumber(BigDecimal v)\n\nWrites a JSON big decimal value.\n\n### writeNumber(BigInteger v)\n\n public abstract void writeNumber(BigInteger v)\n\nWrites a JSON big integer value.\n\n### writeNumber(long v)\n\n public abstract void writeNumber(long v)\n\nWrites a JSON long value.\n\n### writeStartArray()\n\n public abstract void writeStartArray()\n\nWrites a JSON start array character '\\['.\n\n### writeStartObject()\n\n public abstract void writeStartObject()\n\nWrites a JSON start object character '{'.\n\n### writeString(String value)\n\n public abstract void writeString(String value)\n\nWrites a JSON quoted string value."]]
