public static class Java.AmbiguousName

extends Java.Lvalue

This class is special: It does not extend/implement the Atom subclasses, but overrides Atom's "to...()" methods.

Method Detail

toType

public Java.Type toType()

Overrides:

toType in class Java.Atom

getType

public IClass getType()
               throws Java.CompileException

Overrides:

getType in class Java.Atom

isType

public boolean isType()
               throws Java.CompileException

Overrides:

isType in class Java.Atom

compileContext

public int compileContext()
                   throws Java.CompileException

Description copied from class: Java.Rvalue

Generates code that determines the context of the Java.Rvalue and puts it on the operand stack. Most expressions do not have a "context", but some do. E.g. for "x[y]", the context is "x, y". The bottom line is that for statements like "x[y] += 3" the context is only evaluated once.

Overrides:

compileContext in class Java.Rvalue

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

Returns:

The size of the context on the operand stack

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

compileSet

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

Description copied from class: Java.Lvalue

Generates code that stores a value in the Java.Lvalue. Expects the Java.Lvalue's context (see Java.Rvalue.compileContext()) 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).

Overrides:

compileSet in class Java.Lvalue

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
