Method Summary

Methods

Modifier and Type	Method and Description
void	encode(OutputStream output) Encodes this Expression into its XML representation and writes this encoding to the given OutputStream with no indentation.
void	encode(OutputStream output, Indenter indenter) Encodes this Expression into its XML representation and writes this encoding to the given OutputStream with indentation.
URI	getType() Returns the type of the expression.
boolean	returnsBag() Returns whether or not this expression returns, or evaluates to a Bag.

Method Detail

getType

URI getType()

Returns the type of the expression. This may be the data type of an AttributeValue, the return type of a Function, etc.

Returns:

the attribute type of the referenced expression

returnsBag

boolean returnsBag()

Returns whether or not this expression returns, or evaluates to a Bag. Note that Evaluatable, which extends this interface, defines evaluatesToBag which is essentially the same function. This method has been deprecated, and returnsBag is now the preferred way to query all Expressions.

encode

void encode(OutputStream output)

Encodes this Expression into its XML representation and writes this encoding to the given OutputStream with no indentation.

Parameters:

output - a stream into which the XML-encoded data is written

encode

void encode(OutputStream output,
          Indenter indenter)

Encodes this Expression into its XML representation and writes this encoding to the given OutputStream with indentation.

Parameters:

output - a stream into which the XML-encoded data is written

indenter - an object that creates indentation strings
