public interface Const

extends Sym

Const interface Const (constant) class interface. A constant in source program is recorded as a Const instance by using its character string representation as its name. There are access methods to get the value of constants and to record a constant giving its value. Constants are usually represented by symbol table instance in order to represent attributes attached to them. Subclasses of Const is not so fine as type, foe example, int, short, long, unsigned int, unsigned short, unsigned long all belongs to IntConst. To see the type of Const object, use getSymType() of SymInterface.

メソッドの詳細

intValue

public int intValue()

intValue Get the value of this constant. If type conversion is required, the returned value is the result of conversion. "this" should be a constant of type integer, short integer, long integer, or character of either signed or unsigned.

戻り値:

the integer value of this constant.

shortValue

public short shortValue()

shortValue Get the value of this constant. If type conversion is required, the returned value is the result of conversion. "this" should be a constant of type integer, short integer, long integer, or character of either signed or unsigned.

戻り値:

the short int value of this constant.

longValue

public long longValue()

longValue Get the value of this constant. If type conversion is required, the returned value is the result of conversion. "this" should be a constant of type integer, short integer, long integer, or character of either signed or unsigned.

戻り値:

the long int value of this constant.

charValue

public char charValue()

charValue Get the value of this constant. If type conversion is required, the returned value is the result of conversion. "this" should be a constant of type integer, short integer, long integer, or character of either signed or unsigned.

戻り値:

the char value of this constant.

floatValue

public float floatValue()

floatValue Get floating value of this constant. If type conversion is required, the returned value is the result of conversion. "this" should be a constant of type float, or double.

戻り値:

the float value of this constant.

doubleValue

public double doubleValue()

doubleValue Get double value of this constant. If type conversion is required, the returned value is the result of conversion. "this" should be a constant of type float, or double.

戻り値:

the double value of this constant.

getConstSym

public Const getConstSym()

getConstSym If boolean true then return symRoot.intConst1 else if boolean false then return symRoot.intConst0 else if enumeration constant then return corresponding IntConst else return this.

evaluateAsObject

public java.lang.Object evaluateAsObject()

Get the value of this constant symbol. This method is overrided as follows: class returned value IntConst Long FloatConst Double StringConst String Var Initail value (ExpListExp, etc.) if qualified by const, else null.

戻り値:

the constant value of appropriate type.
