      public FlowInfo analyseAssignment(BlockScope currentScope, FlowContext flowContext, FlowInfo flowInfo, Assignment assignment, boolean isCompound)
      Specified by:
      analyseAssignment in class Reference

    • analyseCode

      public FlowInfo analyseCode(BlockScope currentScope, FlowContext flowContext, FlowInfo flowInfo)

    • analyseCode

      public FlowInfo analyseCode(BlockScope currentScope, FlowContext flowContext, FlowInfo flowInfo, boolean valueRequired)
      Description copied from class: Expression
      More sophisticated for of the flow analysis used for analyzing expressions, and be able to optimize out portions of expressions where no actual value is required.
      Overrides:
      analyseCode in class Expression
      Returns:
      The state of initialization after the analysis of the current expression

    • checkFieldAccess

      public TypeBinding checkFieldAccess(BlockScope scope)

    • checkNPE

      public boolean checkNPE(BlockScope scope, FlowContext flowContext, FlowInfo flowInfo, int ttlForFieldCheck)
      Description copied from class: 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.
      Overrides:
      checkNPE in class Reference
      Parameters:
      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
      Returns:
      could this expression be checked by the current implementation?

    • computeConversion

      public void computeConversion(Scope scope, TypeBinding runtimeTimeType, TypeBinding compileTimeType)
      Description copied from class: Expression
      Base types need that the widening is explicitly done by the compiler using some bytecode like i2f. Also check unsafe type operations.
      Overrides:
      computeConversion in class Expression

    • isEquivalent

      public boolean isEquivalent(Reference reference)
      Description copied from class: Reference
      Is the given reference equivalent to the receiver, meaning that both denote the same path of field reads? Used from FlowContext.isNullcheckedFieldAccess(Reference).
      Overrides:
      isEquivalent in class Reference

    • localVariableBinding

      public LocalVariableBinding localVariableBinding()
