Package com.fasterxml.jackson.dataformat.xml.util

Class DefaultXmlPrettyPrinter

java.lang.Object

com.fasterxml.jackson.dataformat.xml.util.DefaultXmlPrettyPrinter

All Implemented Interfaces:

com.fasterxml.jackson.core.PrettyPrinter, com.fasterxml.jackson.core.util.Instantiatable<DefaultXmlPrettyPrinter>, XmlPrettyPrinter, Serializable

public class DefaultXmlPrettyPrinter
extends Object
implements XmlPrettyPrinter, com.fasterxml.jackson.core.util.Instantiatable<DefaultXmlPrettyPrinter>, Serializable

Indentation to use with XML is different from JSON, because JSON requires use of separator characters and XML just basic whitespace.

Note that only a subset of methods of PrettyPrinter actually get called by ToXmlGenerator; because of this, implementation is bit briefer (and uglier...).

Field Detail

_arrayIndenter

protected DefaultXmlPrettyPrinter.Indenter _arrayIndenter

By default, let's use only spaces to separate array values.

_objectIndenter

protected DefaultXmlPrettyPrinter.Indenter _objectIndenter

By default, let's use linefeed-adding indenter for separate object entries. We'll further configure indenter to use system-specific linefeeds, and 2 spaces per level (as opposed to, say, single tabs)

_spacesInObjectEntries

protected boolean _spacesInObjectEntries

By default we will add spaces around colons used to separate object fields and values. If disabled, will not use spaces around colon.

_nesting

protected transient int _nesting

Number of open levels of nesting. Used to determine amount of indentation to use.

_justHadStartElement

protected transient boolean _justHadStartElement

Marker flag set on start element, and cleared if an end element is encountered. Used for suppressing indentation to allow empty elements.

2.3
