Method Details

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.

Specified by:

transformExpression in class Expression

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 ASTNode

Parameters:

visitor - the GroovyCodeVisitor to process this node

getObjectExpression

public Expression getObjectExpression()

setObjectExpression

public void setObjectExpression(Expression objectExpression)

getProperty

public Expression getProperty()

getPropertyAsString

public String getPropertyAsString()

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 ASTNode

Returns:

text representation of this node, or placeholder for unimplemented types

isDynamic

public boolean isDynamic()

isImplicitThis

public boolean isImplicitThis()

setImplicitThis

public void setImplicitThis(boolean implicitThis)

isSafe

public boolean isSafe()

Returns:

is this a safe navigation, i.e. if true then if the source object is null then this navigation will return null

isSpreadSafe

public boolean isSpreadSafe()

setSpreadSafe

public void setSpreadSafe(boolean spreadSafe)

isStatic

public boolean isStatic()

setStatic

public void setStatic(boolean isStatic)

toString

public String toString()

Overrides:

toString in class Object
