### BlockCompiler

    public BlockCompiler()

Method Detail

### compilePush

    public void compilePush(CompilerService compiler,
                            Expression exp)

  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

  Specified by:
    `compilePush` in class `ExpressionCompiler`
  Parameters:
    `compiler` - the compiler service
    `exp` - the expression to be compiled

### compileToValueRepresentation

    public String compileToValueRepresentation(CompilerService compiler,
                                               Expression expr)

  Description copied from class: `ExpressionCompiler`
  Generate Java code to evaluate the expression as a ValueRepresentation

  Overrides:
    `compileToValueRepresentation` in class `ExpressionCompiler`
  Parameters:
    `compiler` - the compiler service
    `expr` - 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 `ValueRepresentation`, and which at run-time will hold the value of the expression

### compileToIterator

    public String compileToIterator(CompilerService compiler,
                                    Expression expr)

  Description copied from class: `ExpressionCompiler`
  Generate Java code to evaluate the expression as a SequenceIterator

  Overrides:
    `compileToIterator` in class `PushExpressionCompiler`
  Parameters:
    `compiler` - the compiler service
    `expr` - 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 `SequenceIterator`, and which at run-time will hold an iterator over the the value of the expression
