Class JsonStringEncoder

java.lang.Object
edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.core.io.JsonStringEncoder
public final class JsonStringEncoder extends Object
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.

    • quoteAsString

      public char[] quoteAsString(String input)
      Method that will escape text contents using JSON standard escaping, and return results as a character array.
      Parameters:
      input - Value String to process
      Returns:
      JSON-escaped String matching input

    • quoteAsString

      public char[] quoteAsString(CharSequence input)
      Overloaded variant of quoteAsString(String).
      Parameters:
      input - Value CharSequence to process
      Returns:
      JSON-escaped String matching input

    • quoteAsString

      public void quoteAsString(CharSequence input, StringBuilder output)
      Method that will quote text contents using JSON standard quoting, and append results to a supplied StringBuilder. Use this variant if you have e.g. a StringBuilder and want to avoid superfluous copying of it.

    • quoteAsUTF8

      public byte[] quoteAsUTF8(String text)

      Parameters:
      text - Value String to process
