PostfixExpression (Groovy 6.0.0-alpha-1)

org.codehaus.groovy.ast.expr.PostfixExpression

```
public class PostfixExpression
extends Expression
```
Represents a postfix unary expression like i++ or value--. The operation is applied after the value is used, returning the original value before modification.
Examples:
- counter++ - return counter then increment it
- index-- - return index then decrement it
See Also:
for pre-increment/pre-decrement operators

- Constructor Detail
  - public PostfixExpression(Expression expression, Token operation)
    
    Creates a postfix expression.
    Parameters:
    expression - the expression to apply the operation to
    operation - the operator token (++ or --)
- Method Detail
  - public Expression getExpression()
    
    Returns the expression being modified by the postfix operation.
    Returns:
    the expression
  - public Token getOperation()
    
    Returns the operator token.
    Returns:
    the ++ or -- token
  - public String getText()
    
    Returns a string representation of this postfix expression.
    Returns:
    the text representation, e.g., "(foo++)"
  - public ClassNode getType()
    
    Returns the type of this postfix expression, which is the type of the operand.
    Returns:
    the type of the inner expression
  - public void setExpression(Expression expression)
    
    Sets the expression to apply the postfix operation to.
    Parameters:
    expression - the expression, typically a variable or property
  - public String toString()
    
    Returns a debug string representation.
    Returns:
    a string like "PostfixExpression[foo++]"
  - public Expression transformExpression(ExpressionTransformer transformer)
    
    Transforms this expression by applying the given transformer to the inner expression, creating a new postfix expression with the transformed operand.
    Parameters:
    transformer - the ExpressionTransformer to apply
    Returns:
    a new postfix expression with transformed inner expression
  - public void visit(GroovyCodeVisitor visitor)
    
    Accepts a GroovyCodeVisitor using the visitor pattern.
    Parameters:
    visitor - the visitor to accept
