All Implemented Interfaces:

Operand, Operand.Register

Enclosing class:

SyntacticOperand

public static class SyntacticOperand.Register

extends SyntacticOperand

implements Operand.Register

The SyntacticOperand.Register class represents a register operand at the source level. This may be an actual register name (e.g. "r21") or it could be a symbolic name for a register that has been renamed by an assembler directive.

Method Detail

asRegister

public Operand.Register asRegister()

Description copied from interface: Operand

The asRegister() method uses virtual dispatch to avoid a cast. If this operand is an instance of Operand.Register it will return itself. Otherwise, it will return null.

Specified by:

asRegister in interface Operand

Overrides:

asRegister in class SyntacticOperand

getRegister

public Register getRegister()

Description copied from interface: Operand.Register

The getRegister() method returns a reference to the register represented by this operand.

Specified by:

getRegister in interface Operand.Register

Returns:

a reference to the register that this operand refers to

simplify

public void simplify(int currentByteAddress,
                     Context c)

Specified by:

simplify in class SyntacticOperand

toString

public java.lang.String toString()
