Constructor Detail

CVoidType

protected CVoidType()

Constructor

checkType

public CType checkType(CContextType context)
                throws UnpositionedError

Checks that this type is valid, throwing an exception if it is not. For class types this check resolves type names into their fully qualified versions and sets the class parameter so that getCClass returns the appropriate singleton.

Parameters:

context - the context in which this type was declared, may be null

Throws:

UnpositionedError - this unpositioned error should be positioned by the calling node of the AST, typically by calling the addPosition method of UnpositionedError

resolveValueType

public void resolveValueType(CExpressionContextType context)
                      throws PositionedError

Compute the value of a specializer expression used to dispatch on a compile-time constant.

Parameters:

context - the context in which this class declaration appears

Throws:

PositionedError - if the check fails

isAlwaysAssignableTo

public boolean isAlwaysAssignableTo(CType dest)

Is this type assignable to the given type by assignment type conversion [JLS2 5.2]. Always false for void.

Parameters:

dest - the destination type

Returns:

true iff assignment is valid

isCastableTo

public boolean isCastableTo(CType dest)

isCastableTo

Parameters:

dest - the destination type

Returns:

cast is valid ?

isVoid

public boolean isVoid()

Check if a type is void type

Overrides:

isVoid in class CType

Returns:

is it void type ?

toString

public String toString()

Transforms this type to a string

Specified by:

toString in class CType

getSignature

public String getSignature()

Transforms this type to a string

Overrides:

getSignature in class CType

appendSignature

public void appendSignature(FastStringBuffer buff)

Transforms this type to a string

getSize

public int getSize()

Returns the size used in stack by value of this type
