Methods Summary

Methods 

Type Params	Return Type	Name and description
	protected void	assignToArray(Expression orig, 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
	protected boolean	doPrimitiveCompare(ClassNode leftType, ClassNode rightType, BinaryExpression binExp) Attempts primitive comparison bytecode generation for the supplied operands.
	protected boolean	doPrimtiveCompare(ClassNode leftType, ClassNode rightType, BinaryExpression binExp) Delegates to doPrimitiveCompare(ClassNode, ClassNode, BinaryExpression).
	protected void	evaluateBinaryExpression(String message, BinaryExpression binExp) * 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 binExp) * Evaluates an operator-assignment expression such as +=. * * Parameters: method - the operator method name * expression - the assignment expression
	protected void	evaluateCompareExpression(MethodCaller compareMethod, BinaryExpression binExp) * 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 binExp) * 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.
	protected int	getOperandType(ClassNode type) Returns the helper index for the supplied operand type.
	protected BinaryExpressionWriter[]	initializeDelegateHelpers() Creates the helper table used for primitive binary-expression 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
