public final class JsonStringEncoder extends Object
Note that methods in here are somewhat optimized, but not ridiculously so. Reason is that conversion method results are expected to be cached so that these methods will not be hot spots during normal operation.
Modifier and Type | Field and Description |
---|---|
protected ByteArrayBuilder |
_bytes
Lazily-constructed builder used for UTF-8 encoding of text values
(quoted and unquoted)
|
protected char[] |
_qbuf
Temporary buffer used for composing quote/escape sequences
|
protected TextBuffer |
_text
Lazily constructed text buffer used to produce JSON encoded Strings
as characters (without UTF-8 encoding)
|
protected static ThreadLocal<SoftReference<JsonStringEncoder>> |
_threadEncoder
This
ThreadLocal contains a SoftReference
to a BufferRecycler used to provide a low-cost
buffer recycling between reader and writer instances. |
