processSpecialNodeTypes

void processSpecialNodeTypes(com.github.javaparser.ast.nodeTypes.NodeWithType<?,com.github.javaparser.ast.type.Type> node,
                             java.lang.String name)

Given a variable declaration of some sort, check it's name and type and if it looks like any of the key type changes between unsafe and atomic queues, perform the conversion to change it's type.

Specified by:

processSpecialNodeTypes in class JavaParsingAtomicQueueGenerator

replaceParentClassesForAtomics

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

Searches all extended or implemented super classes or interfaces for special classes that differ with the atomics version and replaces them with the appropriate class.

patchMethodAsDeprecatedRedirector

private void patchMethodAsDeprecatedRedirector(com.github.javaparser.ast.body.MethodDeclaration methodToPatch,
                                               java.lang.String toMethodName,
                                               com.github.javaparser.ast.type.Type returnType,
                                               com.github.javaparser.ast.body.Parameter... parameters)

Given a method declaration node this method will replace it's code and signature with code to redirect all calls to it to the newMethodName. Method signatures of both methods must match exactly.

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 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

isLongArray

atomicRefArrayType

private com.github.javaparser.ast.type.ClassOrInterfaceType atomicRefArrayType(com.github.javaparser.ast.type.ArrayType in)

atomicLongArrayType

private com.github.javaparser.ast.type.ClassOrInterfaceType atomicLongArrayType()
