Class 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.

      • setOutputProperties

        public void setOutputProperties​(java.util.Properties details)
        Set output properties
        Parameters:
        details - the output serialization properties

      • setMustClose

        public void setMustClose​(boolean mustClose)
        Say whether the output must be closed on completion
        Parameters:
        mustClose - true if the output must be closed

      • getOutputProperties

        public java.util.Properties getOutputProperties()
        Get the output properties
        Returns:
        the properties that were set using setOutputProperties

      • setNormalizationForm

        public void setNormalizationForm​(java.text.Normalizer.Form form)
        Set the Unicode normalizer to be used for normalizing strings.
        Parameters:
        form - the normalization form to be used (default is no normalization)

      • 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

      • 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
