Field Detail

• protected final WriterController controller

  Coordinates the active bytecode-generation state.

Constructor Detail

• public BinaryExpressionHelper(WriterController wc)

  Creates a binary expression helper for the supplied controller.

  Parameters:

  wc - the active writer controller

Method Detail

• protected void assignToArray(Expression parent, Expression receiver, Expression index, Expression rhsValueLoader, boolean safe)

  Emits an array-style assignment using the dynamic putAt protocol.

  Parameters:

  parent - the original assignment expression

  receiver - the array or indexable receiver

  index - the subscript expression

  rhsValueLoader - an expression that reloads the right-hand value

  safe - whether the receiver access is null-safe

• public void eval(BinaryExpression expression)

  Evaluates the supplied binary expression.

  Parameters:

  expression - the expression to compile

• protected void evaluateArrayAssignmentWithOperator(String method, BinaryExpression expression, BinaryExpression leftBinExpr)

  Evaluates a compound assignment whose left-hand side is a subscript expression.

  Parameters:

  method - the operator method name

  expression - the compound assignment expression

  leftBinExpr - the indexed left-hand side

• protected void evaluateBinaryExpression(String message, BinaryExpression expression)

  Evaluates a dynamic binary operator by invoking the named helper method.

  Parameters:

  message - the operator method name

  expression - the expression to compile

• protected void evaluateBinaryExpressionWithAssignment(String method, BinaryExpression expression)

  Evaluates an operator-assignment expression such as +=.

  Parameters:

  method - the operator method name

  expression - the assignment expression

• protected void evaluateCompareExpression(MethodCaller compareMethod, BinaryExpression expression)

  Evaluates a comparison expression, using primitive helpers when possible.

  Parameters:

  compareMethod - the dynamic comparison helper

  expression - the comparison expression

• protected void evaluateCompoundAssign(String assignName, String baseName, BinaryExpression expression)

  GEP-15: dynamic-mode compound-assign codegen. Routes through ScriptBytecodeAdapter.compoundAssign which dispatches to assignName when the receiver responds to it, and falls back to baseName otherwise. The caller stores the helper's return value into the LHS — for the in-place branch this is a no-op store of the receiver back to itself; for the fallback branch it is the usual "x = x.op(y)" assignment.

• public void evaluateElvisEqual(BinaryExpression expression)

  Rewrites and evaluates the Elvis-assignment form.

  Parameters:

  expression - the Elvis-assignment expression

• public void evaluateEqual(BinaryExpression expression, boolean defineVariable)

  Evaluates an assignment expression.

  Parameters:

  expression - the assignment expression

  defineVariable - whether the left-hand side declares a new variable

• public void evaluatePostfixMethod(PostfixExpression expression)

  Evaluates a postfix increment or decrement expression.

  Parameters:

  expression - the postfix expression

• public void evaluatePrefixMethod(PrefixExpression expression)

  Evaluates a prefix increment or decrement expression.

  Parameters:

  expression - the prefix expression

• public void evaluateTernary(TernaryExpression expression)

  Evaluates a ternary or Elvis expression.

  Parameters:

  expression - the expression to compile

• public WriterController getController()

  Returns:

  the active writer controller

• public MethodCaller getIsCaseMethod()

  Returns:

  the helper used for isCase dispatch

• protected void writePostOrPrefixMethod(int op, String method, Expression expression, Expression orig)

  Emits the method call used to implement a prefix or postfix operation.

  Parameters:

  op - the token type

  method - the helper method name

  expression - the receiver expression

  orig - the original prefix/postfix expression
