Method Details

writePostOrPrefixMethod

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

Overrides:

writePostOrPrefixMethod in class BinaryExpressionMultiTypeDispatcher

evaluateBinaryExpressionWithAssignment

protected void evaluateBinaryExpressionWithAssignment(String method,
 BinaryExpression expression)

Overrides:

evaluateBinaryExpressionWithAssignment in class BinaryExpressionMultiTypeDispatcher

evaluateCompoundAssign

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

Description copied from class: BinaryExpressionHelper

GEP-15: dynamic-mode compound-assign codegen. Routes through ScriptBytecodeAdapter.compoundAssign(Object, Object, String, String) 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.

Overrides:

evaluateCompoundAssign in class BinaryExpressionMultiTypeDispatcher

evaluateEqual

public void evaluateEqual(BinaryExpression expression,
 boolean defineVariable)

Overrides:

evaluateEqual in class BinaryExpressionHelper

assignToArray

protected void assignToArray(Expression enclosing,
 Expression receiver,
 Expression subscript,
 Expression rhsValueLoader,
 boolean safe)

Overrides:

assignToArray in class BinaryExpressionMultiTypeDispatcher
