```
public static Bootstraps.BootstrapRef resolve(ClassFile classFile,

    Parameters:
    
    classFile - the owning class file
    
    attrIndex - the bootstrap-method attribute index (from an indy/condy CP item)
    
    Returns:
    
    the resolved reference, or null when the attribute or index is invalid
  - constantValue
```
public static String constantValue(ConstPool constPool,
                                   int cpIndex)
```

    Parameters:
    
    constPool - the constant pool
    
    cpIndex - the constant-pool index
    
    Returns:
    
    a readable representation of the constant
  - readableRecipe
```
public static String readableRecipe(String raw)
```
    Renders a StringConcatFactory recipe to its readable {arg}/{const} form.
