patchAtomicFieldUpdaterAccessorMethods

private void patchAtomicFieldUpdaterAccessorMethods(com.github.javaparser.ast.body.ClassOrInterfaceDeclaration n)

For each method accessor to a field, add in the calls necessary to AtomicFieldUpdaters. Only methods start with so/cas/sv/lv/lp/sp/xchg followed by the field name are processed. Clearly lv, lp and sv are simple field accesses with only so and cas using the AtomicFieldUpdaters.

Parameters:

n - the AST node for the containing class

Generates something like return P_INDEX_UPDATER.getAndSet(this, newValue)

Parameters:

fieldUpdaterFieldName -

newValueName -

Returns:
