Methods Summary

Methods
Type Params	Return Type	Name and description
	`public static BooleanExpression`	`asConditionExecution(AnnotationNode annotation)` Creates a boolean expression that invokes the generated closure backing the supplied annotation.
	`protected static ClosureExpression`	`getOriginalCondition(AnnotationNode annotation)` Returns the original closure expression stored on the annotation, if it has not yet been replaced.
	`protected static Expression`	`getReplacedCondition(AnnotationNode annotation)` Returns the rewritten annotation value once the original closure has been replaced.
	`protected SourceUnit`	`getSourceUnit()` Returns the source unit associated with this visitor.
	`protected static void`	`replaceCondition(AnnotationNode node, Expression expr)` Replaces the annotation value with the generated expression used by later transformation phases.

- Field Detail
  - public static final String GCONTRACTS_ENABLED_VAR
    
    Local variable name used by generated code to guard contract execution.
  - protected final SourceUnit sourceUnit
    
    Source unit currently being visited.
- Constructor Detail
  - public BaseVisitor(SourceUnit sourceUnit, ReaderSource source)
    
    Creates a visitor bound to the supplied source unit.
    Parameters:
    sourceUnit - the source unit currently being transformed
    source - the reader source backing the source unit
- Method Detail
  - public static BooleanExpression asConditionExecution(AnnotationNode annotation)
    
    Creates a boolean expression that invokes the generated closure backing the supplied annotation.
    Parameters:
    annotation - the contract annotation whose closure should be executed
    Returns:
    a boolean expression that evaluates the generated closure
  - protected static ClosureExpression getOriginalCondition(AnnotationNode annotation)
    
    Returns the original closure expression stored on the annotation, if it has not yet been replaced.
    Parameters:
    annotation - the annotation to inspect
    Returns:
    the original closure expression, or null if it has already been rewritten
  - protected static Expression getReplacedCondition(AnnotationNode annotation)
    
    Returns the rewritten annotation value once the original closure has been replaced.
    Parameters:
    annotation - the annotation to inspect
    Returns:
    the replacement expression, or null while the original closure is still present
  - protected SourceUnit getSourceUnit()
    
    Returns the source unit associated with this visitor.
    Returns:
    the current source unit
  - protected static void replaceCondition(AnnotationNode node, Expression expr)
    
    Replaces the annotation value with the generated expression used by later transformation phases.
    Parameters:
    node - the annotation to update
    expr - the replacement expression
