# Interface CodeModel

All Superinterfaces:
  `AttributedElement, ClassFileElement, CompoundElement<CodeElement>, Iterable<CodeElement>, MethodElement`

All Known Subinterfaces:
  `CodeAttribute`

public sealed interface CodeModel extends CompoundElement<CodeElement>, AttributedElement, MethodElement permits CodeAttribute (not exhaustive)
Models the body of a method (the `Code` attribute). A `Code` attribute is viewed as a composition of `CodeElement`s, which is the only way to access `Instruction`s; the order of elements of a code model is significant.

A `CodeModel` is obtained from `MethodModel.code()`, or in the traversal of the member elements of a method.

`MethodBuilder.withCode(Consumer)` is the main way to build code models. `MethodBuilder.transformCode(CodeModel, CodeTransform)` and `CodeBuilder.transforming(CodeTransform, Consumer)` allow creating new `Code` attributes by selectively processing the original code elements and directing the results to a code builder.

A `Code` attribute holds attributes, but they are usually not member elements, but are decomposed to `PseudoInstruction`, accessible according to `ClassFile.DeadLabelsOption`, `ClassFile.DebugElementsOption`, and `ClassFile.LineNumbersOption`. `StackMapTableAttribute` can only be accessed via explicit attribute reading, as it is considered a derived property from the code body.

  - ### parent

    Optional<MethodModel> parent()
    Returns the enclosing method, if known.
    Returns:
      the enclosing method, if known

  - ### exceptionHandlers
