Method Detail

getType

public IClass getType()

Overrides:

getType in class Java.Atom

compileGet

public IClass compileGet(ClassFile.CodeAttribute codeAttribute)
                  throws Java.CompileException

Description copied from class: Java.Rvalue

Generates code that determines the value of the Java.Rvalue and puts it on the operand stack. This method relies on that the "context" of the Java.Rvalue is on top of the operand stack (see Java.Rvalue.compileContext(ClassFile.CodeAttribute)).

Overrides:

compileGet in class Java.Rvalue

Following copied from class: net.janino.Java.Rvalue

Returns:

The type of the Java.Rvalue

getConstantValue

public java.lang.Object getConstantValue()

Description copied from class: Java.Rvalue

Attempts to evaluate as a constant expression.

Overrides:

getConstantValue in class Java.Rvalue

Following copied from class: net.janino.Java.Rvalue

Returns:

null if value is not constant; otherwise a String, Byte, Short, Integer, Boolean, Character, Float, Long or Double
