    • checkNPE

      public boolean checkNPE(BlockScope scope, FlowContext flowContext, FlowInfo flowInfo, int ttlForFieldCheck)
      Beschreibung aus Klasse kopiert: Expression
      Check this expression against potential NPEs, which may occur:
      • if the expression is the receiver in a field access, qualified allocation, array reference or message send incl. implicit message sends like it happens for the collection in a foreach statement.
      • if the expression is subject to unboxing
      • if the expression is the exception in a throw statement
      If a risk of NPE is detected report it to the context. If the expression denotes a local variable, mark it as checked, which affects the flow info.
      Setzt außer Kraft:
      checkNPE in Klasse Reference
      Parameter:
      scope - the scope of the analysis
      flowContext - the current flow context
      flowInfo - the upstream flow info; caveat: may get modified
      ttlForFieldCheck - if this is a reference to a field we will mark that field as nonnull for the specified timeToLive
      Gibt zurück:
      could this expression be checked by the current implementation?

    • computeConversion

      public void computeConversion(Scope scope, TypeBinding runtimeTimeType, TypeBinding compileTimeType)
      Beschreibung aus Klasse kopiert: Expression
      Base types need that the widening is explicitly done by the compiler using some bytecode like i2f. Also check unsafe type operations.
