Method Detail

convert

public ValueRepresentation convert(Object object,
                                   XPathContext context)
                            throws XPathException

Description copied from class: JPConverter

Convert a Java object to an equivalent XPath value

Specified by:

convert in class JPConverter

Parameters:

object - the java object to be converted

context - the XPath dynamic evaluation context

Returns:

the XPath value resulting from the conversion

Throws:

XPathException - if the conversion is not possible or if it fails

getItemType

public ItemType getItemType()

Description copied from class: JPConverter

Get the item type of the XPath value that will result from the conversion

Specified by:

getItemType in class JPConverter

Returns:

the XPath item type

getCardinality

public int getCardinality()

Description copied from class: JPConverter

Get the cardinality of the XPath value that will result from the conversion

Overrides:

getCardinality in class JPConverter

Returns:

the cardinality of the result

compile

public String compile(String var,
                      CodeGeneratorService compiler)

Description copied from class: JPConverter

Generate a Java expression (as text) that can be used to implement this conversion when compiling a query

Overrides:

compile in class JPConverter

Parameters:

var - the Java variable that will hold the Java value to be converted

compiler - provides callback services

Returns:

a Java expression (as text) that implements the conversion. The result of the Java expression must be of type ValueRepresentation, and if the cardinality of the converter is exactly one then it must be of type Item.
