# Class TemporaryVariableExpression

java.lang.Object
org.codehaus.groovy.ast.ASTNode
org.codehaus.groovy.ast.AnnotatedNode
org.codehaus.groovy.ast.expr.Expression
org.codehaus.groovy.transform.sc.TemporaryVariableExpression

All Implemented Interfaces:
  `GroovydocHolder<AnnotatedNode>`, `NodeMetaDataHandler`

public class TemporaryVariableExpression extends Expression
A front-end class for `ExpressionAsVariableSlot` which allows defining temporary variables loaded from variable slots directly at the AST level, without any knowledge of `AsmClassGenerator`.

Since:
  2.4.0

  - ### getType

    public ClassNode getType()
    Description copied from class: `Expression`
    Returns the type of this expression. If the type has not been explicitly set, this method returns a dynamic type to support dynamic typing.
    Overrides:
      `getType` in class `Expression`
    Returns:
      the `ClassNode` representing this expression's type

  - ### remove

    public void remove(WriterController controller)

  - ### 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
