Constructor Details

IndyBinHelper

public IndyBinHelper(WriterController wc)

Creates an indy-aware binary-expression helper.

Method Details

writePostOrPrefixMethod

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

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

Overrides:

writePostOrPrefixMethod in class BinaryExpressionHelper

Parameters:

op - the token type

method - the helper method name

expression - the receiver expression

orig - the original prefix/postfix expression

evaluateCompoundAssign

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

GEP-15: emit invokedynamic to IndyInterface.bootstrap(java.lang.invoke.MethodHandles.Lookup, java.lang.String, java.lang.invoke.MethodType, java.lang.String, int) with the IndyInterface.CallType.COMPOUND_ASSIGN call type (resolved by IndyCompoundAssign), replacing the uncached static call into ScriptBytecodeAdapter.compoundAssign. Subscript LHS (e.g. a[i] += b) is out of GEP-15 scope and stays on the legacy path.

Overrides:

evaluateCompoundAssign in class BinaryExpressionHelper
