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 XPathExceptionOutput 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 XPathExceptionOutput 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
public void endArray() throws XPathExceptionOutput the end of an array- Throws:
XPathException- if any failure occurs
-
startMap
public void startMap(boolean oneLiner) throws XPathExceptionOutput 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
public void endMap() throws XPathException- Throws:
XPathException
-
close
public void close() throws XPathExceptionEnd of the document.- Throws:
XPathException
