JsonHandlerXML

public JsonHandlerXML(XPathContext context,
 RetainedStaticContext rsc,
 int flags)
               throws XPathException

Make the handler to construct the XML tree representation for JSON

Parameters:

context - the context in which the result tree is to be built

rsc - the retained static context, used for schema information and for the base URI of the constructed tree

flags - flags indicating the chosen options

Throws:

XPathException - if initialization fails, for example because of problems loading the schema

Method Details

setType

public void setType(String name,
 SchemaType st)

Record a SchemaType for a particular name

Parameters:

name - the name to be used for the type, e.g. "arrayType"

st - the schema type to be used for typing such entities

setKey

public boolean setKey(UnicodeString key)

Set the key to be written for the next entry in an object/map

Overrides:

setKey in class JsonHandler

Parameters:

key - the key for the entry (null implies no key) in unescaped form (backslashes, if present, do not signal an escape sequence)

Returns:

true if the key is already present in the map, false if it is not

getResult

public Item getResult()
               throws XPathException

Return the complete parsed result

Overrides:

getResult in class JsonHandler

Returns:

the XML document for this JSON

Throws:

XPathException - if an error occurs downstream

startArray

public void startArray()
                throws XPathException

Open a new array

Overrides:

startArray in class JsonHandler

Throws:

XPathException - if a dynamic error occurs

endArray

public void endArray()
              throws XPathException

Close the current array

Overrides:

endArray in class JsonHandler

Throws:

XPathException - if a dynamic error occurs

startMap

public void startMap()
              throws XPathException

Start a new object/map

Overrides:

startMap in class JsonHandler

Throws:

XPathException - if a dynamic error occurs

endMap

public void endMap()
            throws XPathException

Close the current object/map

Overrides:

endMap in class JsonHandler

Throws:

XPathException - if a dynamic error occurs

writeNumeric

public void writeNumeric(String asString,
 Item parsedValue)
                  throws XPathException

Write a numeric value

Overrides:

writeNumeric in class JsonHandler

Parameters:

asString - the string representation of the value

parsedValue - the double representation of the value

Throws:

XPathException - if a dynamic error occurs

                 throws XPathException

Write a string value

Overrides:

writeString in class JsonHandler

Parameters:

val - the string to be written. This will be in unescaped form if unescaping was requested in the flags, otherwise it may contain JSON escape sequences
