JsonParser

public JsonParser()

Create a JSON parser

Method Details

parse

public void parse(String input,
 int flags,
 JsonHandler handler,
 XPathContext context)
           throws XPathException

Parse the JSON string according to supplied options

Parameters:

input - JSON input string

flags - options for the conversion as a map of xs:string : value pairs

handler - event handler to which parsing events are notified

context - XPath evaluation context

Throws:

XPathException - if the syntax of the input is incorrect

getFlags

public static int getFlags(Map<String,GroundedValue> options,
 boolean allowValidate,
 boolean isSchemaAware)
                    throws XPathException

Extract the requested JSON parsing options as a set of flags in a bit-significant integer

Parameters:

options - the supplied options map

allowValidate - true if the validate option is permitted

isSchemaAware - true if the processor is schema-aware (only relevant when allowValidate=true)

Returns:

the options as a sef of flags

Throws:

XPathException - if any options are invalid

unescape

public static String unescape(String literal,
 int flags,
 String errorCode,
 int lineNumber)
                       throws XPathException

Unescape a JSON string literal

Parameters:

literal - the string literal to be processed

flags - parsing options

errorCode - Error code

lineNumber - the line number

Returns:

the result of parsing and conversion to XDM

Throws:

XPathException - if a dynamic error occurs (such as invalid JSON input)

showToken

public static String showToken(JsonParser.JsonToken token,
 String currentTokenValue)

setNumberParser

public void setNumberParser(Map<String,GroundedValue> options,
 XPathContext context)
                     throws XPathException

Throws:

XPathException
