Method Detail

compileSet

public abstract void compileSet(ClassFile.CodeAttribute codeAttribute,
                                IClass valueType,
                                java.lang.Object optionalConstantValue)
                         throws Java.CompileException

Generates code that stores a value in the Java.Lvalue. Expects the Java.Lvalue's context (see Java.Rvalue.compileContext(net.janino.ClassFile.CodeAttribute)) and a value of type "valueType" on the operand stack.

If optionalConstantValue is not null, then the stack top value is identical to it; this allows for "primitive constant assignment conversion" (JLS 5.2).
