Class JSONEmitter
java.lang.Object
net.sf.saxon.serialize.JSONEmitter
This class implements the back-end text generation of the JSON serialization method. It takes
as input a sequence of event-based calls such as startArray, endArray, startMap, endMap,
and generates the lexical JSON output.

Method Details
-
setOutputProperties
Set output properties- Parameters:
details
- the output serialization properties
-
getOutputProperties
Get the output properties- Returns:
- the properties that were set using setOutputProperties
-
setNormalizer
Set the Unicode normalizer to be used for normalizing strings.- Parameters:
normalizer
- the normalizer to be used
-
setCharacterMap
Set the CharacterMap to be used, if any- Parameters:
map
- the character map
-
writeKey
Output the key for an entry in a map. The corresponding value must be supplied in the following call.- Parameters:
key
- the value of the key, without any escaping of special characters- Throws:
XPathException
- if any error occurs
-
writeAtomicValue
Append a singleton value (number, string, or boolean) to the output- Parameters:
item
- the atomic value to be appended, or null to append "null"- Throws:
XPathException
- if the operation fails
-
startArray
Output the start of an array. This call must be followed by the members of the array, followed by a call onendArray()
.- Parameters:
oneLiner
- True if the caller thinks the value should be output without extra newlines after the open bracket or before the close bracket, even when indenting is on.- Throws:
XPathException
- if any failure occurs
-
endArray
Output the end of an array- Throws:
XPathException
- if any failure occurs
-
startMap
Output the start of an map. This call must be followed by the entries in the map (each starting with a call onwriteKey(String)
, followed by a call onendMap()
.- Parameters:
oneLiner
- True if the caller thinks the value should be output without extra newlines after the open bracket or before the close bracket, even when indenting is on.- Throws:
XPathException
- if any failure occurs
-
endMap
- Throws:
XPathException
-
close
End of the document.- Throws:
XPathException
