Class JSONEmitter

java.lang.Object

net.sf.saxon.serialize.JSONEmitter

public class JSONEmitter
extends java.lang.Object

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.

JSONEmitter

public JSONEmitter(PipelineConfiguration pipe,
                   javax.xml.transform.stream.StreamResult result,
                   java.util.Properties outputProperties)
            throws XPathException

Throws:

XPathException

Method Detail

setOutputProperties

public void setOutputProperties(java.util.Properties details)

Set output properties

Parameters:

details - the output serialization properties

getOutputProperties

public java.util.Properties getOutputProperties()

Get the output properties

Returns:

the properties that were set using setOutputProperties

setNormalizer

public void setNormalizer(Normalizer normalizer)

Set the Unicode normalizer to be used for normalizing strings.

Parameters:

normalizer - the normalizer to be used

setCharacterMap

public void setCharacterMap(CharacterMap map)

Set the CharacterMap to be used, if any

Parameters:

map - the character map

writeKey

public void writeKey(java.lang.String key)
              throws XPathException

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

public void writeAtomicValue(AtomicValue item)
                      throws XPathException

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

public void startArray(boolean oneLiner)
                throws XPathException

Output the start of an array. This call must be followed by the members of the array, followed by a call on endArray().

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

public void endArray()
              throws XPathException

Output the end of an array

Throws:

XPathException - if any failure occurs

startMap

public void startMap(boolean oneLiner)
              throws XPathException

Output the start of an map. This call must be followed by the entries in the map (each starting with a call on writeKey(String), followed by a call on endMap().

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

public void endMap()
            throws XPathException

Throws:

XPathException

close

public void close()
           throws XPathException

End of the document.

Throws:

XPathException
