Method Summary

void	acceptVisit(BCVisitor visit) Accept a visit from a BCVisitor, calling the appropriate methods to notify the visitor that it has entered this entity, and to provide it with the proper callbacks for each sub-entity owned by this one.
double	getDoubleValue() Get the value of this double constant.
BCField	getField() Return the owning field.
float	getFloatValue() Get the value of this float constant.
int	getIntValue() Get the value of this int constant, or 0 if not set.
long	getLongValue() Get the value of this long constant.
String	getStringValue() Get the value of this string constant.
Class	getType() Return the type of constant this attribute represents (String.class, int.class, etc), or null if not set.
BCClass	getTypeBC() Return the bytecode for the type of constant this attribute represents.
String	getTypeName() Return the type of constant this attribute represents, or null if not set.
Object	getValue() Return the value of this constant as an Object of the appropriate type (String, Integer, Double, etc), or null if not set.
int	getValueIndex() Return the ConstantPool index of the ConstantEntry holding the value of this constant.
void	setDoubleValue(double value) Set the value of this double constant.
void	setFloatValue(float value) Set the value of this float constant.
void	setIntValue(int value) Set the value of this int constant.
void	setLongValue(long value) Set the value of this long constant.
void	setStringValue(String value) Set the value of this string constant.
void	setValue(Object value) Set the value of this constant using the appropriate wrapper Object type (String, Integer, Double, etc).
void	setValueIndex(int valueIndex) Set the ConstantPool of the ConstantEntry holding the value of this constant.
