Member Function Documentation

cast_to()

CConstant * Puma::CConstant::cast_to

(

CTypeInfo *

t

)

const

Cast the value to the given type.

Parameters

t	The type to which to cast.

Returns

A new object with the casted value. Has to be destroyed by the caller.

compute() [1/2]

CConstant * Puma::CConstant::compute

(

int

oper

)

const

Compute the resulting value when applying the given unary operator to the value.

Parameters

oper	The operator to apply to the value (token type).

Returns

A new object with the computed value. Has to be destroyed by the caller.

compute() [2/2]

CConstant * Puma::CConstant::compute	(	int	oper,
		const CConstant *	v
	)		const

Compute the resulting value when applying the given binary operator to this and the given value.

Parameters

oper	The operator to apply to the values (token type).
v	The other operand to the operator.

Returns

A new object with the computed value. Has to be destroyed by the caller.
