java.lang.Object com.fasterxml.jackson.core.io.JsonStringEncoder
public final class JsonStringEncoder
Helper class used for efficient encoding of JSON String values (including JSON field names) into Strings or UTF-8 byte arrays.
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.
Field Summary | |
---|---|
protected ByteArrayBuilder |
_byteBuilder
Lazily-constructed builder used for UTF-8 encoding of text values (quoted and unquoted) |
protected char[] |
_quoteBuffer
Temporary buffer used for composing quote/escape sequences |
protected TextBuffer |
_textBuffer
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 SoftRerefence
to a BufferRecycler used to provide a low-cost
buffer recycling between reader and writer instances. |

byte[] |
encodeAsUTF8(String text)
Will encode given String as UTF-8 (without any quoting), return resulting byte array. |
static JsonStringEncoder |
getInstance()
Factory method for getting an instance; this is either recycled per-thread instance, or a newly constructed one. |
char[] |
quoteAsString(String input)
Method that will quote text contents using JSON standard quoting, and return results as a character array |
byte[] |
quoteAsUTF8(String text)
Will quote given JSON String value using standard quoting, encode results as UTF-8, and return result as a byte array. |
