Method Details

writeMap

public void writeMap(MapWriter.EntryWriter ew)
              throws IOException

Description copied from interface: MapWriter

Writes this object's entries out to ew.

Specified by:

writeMap in interface MapWriter

Throws:

IOException

_get

public Object _get(String path)

Description copied from interface: NavigableObject

Get a child object value using json path. This usually ends up in String split operations use a list of strings where performance is important

Specified by:

_get in interface NavigableObject

Parameters:

path - the full path to that object such as a/b/c[4]/d etc

Returns:

the found value or default

_get

public Object _get(List<String> path,
 Object def)

Description copied from interface: NavigableObject

Get a child object value using json path

Specified by:

_get in interface NavigableObject

Parameters:

path - the full path to that object such as ["a","b","c[4]","d"] etc

def - the default

Returns:

the found value or default

toString

public String toString()

Overrides:

toString in class AbstractMap<String,V>
