Models the body of a method (theCode attribute). ACode attribute is viewed as acomposition ofCodeElements, which is the only way to accessInstructions; the order of elements of a code model is significant.

ACodeModel is obtained fromMethodModel.code(), or in the traversal of the member elements of a method.

MethodBuilder.withCode(java.util.function.Consumer<? super java.lang.classfile.CodeBuilder>) is the main way to build code models.MethodBuilder.transformCode(java.lang.classfile.CodeModel, java.lang.classfile.CodeTransform) andCodeBuilder.transforming(java.lang.classfile.CodeTransform, java.util.function.Consumer<java.lang.classfile.CodeBuilder>) allow creating newCode attributes by selectively processing the original code elements and directing the results to a code builder.

ACode attribute holds attributes, but they are usually not member elements, but are decomposed toPseudoInstruction, accessible according toClassFile.DeadLabelsOption,ClassFile.DebugElementsOption, andClassFile.LineNumbersOption.StackMapTableAttribute can only be accessed viaexplicit attribute reading, as it is considered a derived property from the code body.
