Method Details

getText

public String getText()

Description copied from class: ASTNode

Returns a human-readable text representation of this AST node. Used for debugging and error messages. Default implementation returns a message indicating the representation is not yet implemented for this node type.

Overrides:

getText in class PropertyExpression

Returns:

text representation of this node, or placeholder for unimplemented types

transformExpression

public Expression transformExpression(ExpressionTransformer transformer)

Description copied from class: Expression

Transforms this expression and any nested expressions according to the provided transformer. This method is called during AST transformation phases and must recursively transform any nested expressions to support full AST tree transformation.

Overrides:

transformExpression in class PropertyExpression

Parameters:

transformer - the ExpressionTransformer to apply

Returns:

a transformed copy of this expression (or this expression itself if no changes are needed)

visit

public void visit(GroovyCodeVisitor visitor)

Description copied from class: ASTNode

Accepts a code visitor for AST traversal and transformation. Subclasses must implement this method to support visitor pattern-based processing. The visitor pattern enables decoupling of AST structure from processing logic.

Overrides:

visit in class PropertyExpression

Parameters:

visitor - the GroovyCodeVisitor to process this node
