Class Inheritance
All Implemented Interfaces

Imports
tools.jackson.core.JacksonException, .JsonGenerator, .PrettyPrinter, tools.jackson.core.util.Separators.Spacing
PrettyPrinter implementation that adds no indentation, just implements everything necessary for value output to work as expected, and provide simpler extension points to allow for creating simple custom implementations that add specific decoration or overrides. Since behavior then is very similar to using no pretty printer at all, usually sub-classes are used.

Beyond purely minimal implementation, there is limited amount of configurability which may be useful for actual use: for example, it is possible to redefine separator used between root-level values (default is single space; can be changed to line-feed).

Note

does NOT implement Instantiatable since this is a stateless implementation; that is, a single instance can be shared between threads.

public void beforeArrayValues(JsonGenerator g) throws JacksonException

Implements tools.jackson.core.PrettyPrinter.beforeArrayValues.

Doc from tools.jackson.core.PrettyPrinter.beforeArrayValues.

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.

Doc from tools.jackson.core.PrettyPrinter.beforeObjectEntries.

Method called after object start marker has been output, and right before the Name of the first property is to be output. It is not called for objects without properties.

Default handling does not output anything, but pretty-printer is free to add any white space decoration.

writeArrayValueSeparatorback to summary
public void writeArrayValueSeparator(JsonGenerator g) throws JacksonException

Implements tools.jackson.core.PrettyPrinter.writeArrayValueSeparator.

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 values.

Annotations

public void writeEndArray(JsonGenerator g, int nrOfValues) throws JacksonException

Implements tools.jackson.core.PrettyPrinter.writeEndArray.

Doc from tools.jackson.core.PrettyPrinter.writeEndArray.

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.

public void writeEndObject(JsonGenerator g, int nrOfEntries) throws JacksonException

Implements tools.jackson.core.PrettyPrinter.writeEndObject.

Doc from tools.jackson.core.PrettyPrinter.writeEndObject.

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.

public void writeObjectEntrySeparator(JsonGenerator g) throws JacksonException

Implements tools.jackson.core.PrettyPrinter.writeObjectEntrySeparator.

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.

Annotations
@Override
writeObjectNameValueSeparatorback to summary
public void writeObjectNameValueSeparator(JsonGenerator g) throws JacksonException

Implements tools.jackson.core.PrettyPrinter.writeObjectNameValueSeparator.

Method called after the Object property name has been output, but before the value is output.

Default handling will just output a single colon to separate the two, without additional spaces.

public void writeRootValueSeparator(JsonGenerator g) throws JacksonException

Implements tools.jackson.core.PrettyPrinter.writeRootValueSeparator.

Doc from tools.jackson.core.PrettyPrinter.writeRootValueSeparator.

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).
