public interface PrettyPrinter
Interface for objects that implement pretty printer functionality, such as indentation. Pretty printers are used to add white space in output JSON content, to make results more human readable. Usually this means things like adding linefeeds and indentation.

Method Detail
-
writeRootValueSeparator
void writeRootValueSeparator(JsonGenerator jg) throws IOException, JsonGenerationException
Method called after a root-level value has been completely output, and before another value is to be output.Default handling (without pretty-printing) will output a space, to allow values to be parsed correctly. Pretty-printer is to output some other suitable and nice-looking separator (tab(s), space(s), linefeed(s) or any combination thereof).
- Throws:
IOException
JsonGenerationException
-
writeStartObject
void writeStartObject(JsonGenerator jg) throws IOException, JsonGenerationException
Method called when an Object value is to be output, before any fields are output.Default handling (without pretty-printing) will output the opening curly bracket. Pretty-printer is to output a curly bracket as well, but can surround that with other (white-space) decoration.
- Throws:
IOException
JsonGenerationException
-
writeEndObject
void writeEndObject(JsonGenerator jg, int nrOfEntries) throws IOException, JsonGenerationException
Method called after an Object value has been completely output (minus closing curly bracket).Default handling (without pretty-printing) will output the closing curly bracket. Pretty-printer is to output a curly bracket as well, but can surround that with other (white-space) decoration.
- Parameters:
nrOfEntries
- Number of direct members of the array that have been output- Throws:
IOException
JsonGenerationException
-
writeObjectEntrySeparator
void writeObjectEntrySeparator(JsonGenerator jg) throws IOException, JsonGenerationException
Method called after an object entry (field:value) has been completely output, and before another value is to be output.Default handling (without pretty-printing) will output a single comma to separate the two. Pretty-printer is to output a comma as well, but can surround that with other (white-space) decoration.
- Throws:
IOException
JsonGenerationException
-
writeObjectFieldValueSeparator
void writeObjectFieldValueSeparator(JsonGenerator jg) throws IOException, JsonGenerationException
Method called after an object field has been output, but before the value is output.Default handling (without pretty-printing) will output a single colon to separate the two. Pretty-printer is to output a colon as well, but can surround that with other (white-space) decoration.
- Throws:
IOException
JsonGenerationException
-
writeStartArray
void writeStartArray(JsonGenerator jg) throws IOException, JsonGenerationException
Method called when an Array value is to be output, before any member/child values are output.Default handling (without pretty-printing) will output the opening bracket. Pretty-printer is to output a bracket as well, but can surround that with other (white-space) decoration.
- Throws:
IOException
JsonGenerationException
-
writeEndArray
void writeEndArray(JsonGenerator jg, int nrOfValues) throws IOException, JsonGenerationException
Method called after an Array value has been completely output (minus closing bracket).Default handling (without pretty-printing) will output the closing bracket. Pretty-printer is to output a bracket as well, but can surround that with other (white-space) decoration.
- Parameters:
nrOfValues
- Number of direct members of the array that have been output- Throws:
IOException
JsonGenerationException
-
writeArrayValueSeparator
void writeArrayValueSeparator(JsonGenerator jg) throws IOException, JsonGenerationException
Method called after an array value has been completely output, and before another value is to be output.Default handling (without pretty-printing) will output a single comma to separate the two. Pretty-printer is to output a comma as well, but can surround that with other (white-space) decoration.
- Throws:
IOException
JsonGenerationException
-
beforeArrayValues
void beforeArrayValues(JsonGenerator jg) throws IOException, JsonGenerationException
Method called after array start marker has been output, and right before the first value is to be output. It is not called for arrays with no values.Default handling does not output anything, but pretty-printer is free to add any white space decoration.
- Throws:
IOException
JsonGenerationException
-
beforeObjectEntries
void beforeObjectEntries(JsonGenerator jg) throws IOException, JsonGenerationException
Method called after object start marker has been output, and right before the field name of the first entry is to be output. It is not called for objects without entries.Default handling does not output anything, but pretty-printer is free to add any white space decoration.
- Throws:
IOException
JsonGenerationException
