Package proguard.evaluation.executor

Class ObjectGetClassExecutor

java.lang.Object
proguard.evaluation.executor.ObjectGetClassExecutor
All Implemented Interfaces:
Executor
public class ObjectGetClassExecutor extends Object implements Executor
This Executor provides an implementation for Executor.getMethodResult(proguard.evaluation.executor.MethodExecutionInfo, proguard.evaluation.ValueCalculator) which resolves all types of 'Object'.getClass Class calls based on the classes in the class pools.

For example classA.getClass() and classB.getClass()

  • Method Details

    • getMethodResult

      public MethodResult getMethodResult(MethodExecutionInfo methodExecutionInfo, ValueCalculator valueCalculator)
      Description copied from interface: Executor
      Calculate the result of a given method. This is the return value for a non-constructor method (null if it returns void) and the instantiated object for a constructor.
      Specified by:
      getMethodResult in interface Executor
      Parameters:
      methodExecutionInfo - Information about the called method.
      valueCalculator - a function mapping the result of a method invocation (can be an Object with the result if the executor calculates a real value or a Model) to the appropriate Value used by the analysis. Should also be used to create values of unknown value since the executor might be able to provide additional information on them even if the value itself is not known (e.g., on the identifier of the returned value).
      Returns:
      The result of the method call, including information on the returned value or values or arguments on which side effects happened during the method execution. If the executor is not able to provide any additional information for any reason the returned value should be MethodResult.invalidResult(), so that the caller can know that execution failed and just provide its best approximation of the result.

    • getSupportedMethodSignatures

      public Set<MethodSignature> getSupportedMethodSignatures()
      Description copied from interface: Executor
      Get a list of method signatures that indicate which methods are supported by this executor.

      The returned methods should be exactly the ones that the executor is expected to be able to handle. The invocation unit does not make any additional assumption on the executors available to execute a method and will match them iff the signature of the target method matches exactly.

      Only full method signatures should be returned, the invocation unit does not support wildcards.

      Specified by:
      getSupportedMethodSignatures in interface Executor
      Returns:
      a set of methods the executor can handle.
