Java.Cast

public Java.Cast(Scanner.Location location,
                 Java.Type targetType,
                 Java.Rvalue value)

Method Detail

getType

public IClass getType()
               throws Java.CompileException

Overrides:

getType in class Java.Atom

compileGet

public IClass compileGet()
                  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()).

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()
                                  throws Java.CompileException

Description copied from class: Java.Rvalue

Attempts to evaluate as a constant expression.

Expression type	Return value type
String	String
byte	Byte
short	Chort
int	Integer
boolean	Boolean
char	Character
float	Float
long	Long
double	Double
null	Java.Rvalue.CONSTANT_VALUE_NULL

Overrides:

getConstantValue in class Java.Rvalue
