## [Java] Class ExpressionAsVariableSlot

- org.codehaus.groovy.classgen.asm.ExpressionAsVariableSlot

-     public class ExpressionAsVariableSlot
      extends BytecodeExpression

  Helper class that takes an Expression and if visited will load it normally, storing the result in a helper variable, which then can be requested after the visit is completed. A copy of the variable will stay on the stack. Subsequent visits will load the stored value instead of visiting the expression again

    Methods
    Type Params | Return Type | Name and description
    --- | --- | ---
    `` | `public int` | `getIndex()` returns the index of the bytecode variable
    `` | `public String` | `getText()` * * 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. * * Returns: text representation of this node, or placeholder for unimplemented types
    `` | `public void` | `visit(org.objectweb.asm.MethodVisitor mv)` * Emits bytecode instructions using the provided method visitor. * * Parameters: `visitor` - the ASM method visitor to generate bytecode
