ItemCheckerCompiler
public ItemCheckerCompiler()
compileToItem
public String compileToItem(CompilerService compiler,
Expression expr)
- Description copied from class:
ExpressionCompiler
- Generate Java code to evaluate the expression as an Item
- Overrides:
compileToItem
in class SequenceExpressionCompiler
- Parameters:
compiler
- the compiler serviceexpr
- the expression to be compiled
- Returns:
- a simple Java expression (usually the name of a variable that
has been declared) which will be of class
Item
,
and which will hold the value of the expression at run-time (or hold null,
representing an empty sequence).
compileToIterator
public String compileToIterator(CompilerService compiler,
Expression expr)
- Description copied from class:
ExpressionCompiler
- Generate Java code to evaluate the expression as a SequenceIterator
- Specified by:
compileToIterator
in class ExpressionCompiler
- Parameters:
compiler
- the compiler serviceexpr
- the XPath expression to be compiled
- Returns:
- a simple Java expression (usually the name of a variable that
has been declared) which will be of class
SequenceIterator
,
and which at run-time will hold an iterator over the the value of the XPath expression
compilePush
public void compilePush(CompilerService compiler,
Expression expr)
- Description copied from class:
ExpressionCompiler
- Generate Java code to execute the expression in push mode, that is, code to
write events to the current output Receiver
- Overrides:
compilePush
in class SequenceExpressionCompiler
- Parameters:
compiler
- the compiler serviceexpr
- the expression to be compiled
