Constructor Detail

EnumerationExpression

public EnumerationExpression(ASTInfo info,
                             EnumerationType type,
                             String constant)

Constructs a new enumeration expression.

Parameters:

info -

type -

constant - an enumeration constant

Method Detail

getConstant

public String getConstant()

Returns the enumeration constant (literal).

Returns:

the enumeration constant

getValue

public EnumerationImpl getValue()

Returns the enumeration value.

Returns:

the enumeration value

isParseTimeConstant

public boolean isParseTimeConstant()

Description copied from class: Expression

Returns true if the value of the expression is known in parse time. E.g. constant literals, enumerations, types (without free types).

Overrides:

isParseTimeConstant in class Expression

Returns:

true if the expression value is known during parsing

See Also:

Expression.getParseTimeConstant()

getParseTimeConstant

public Object getParseTimeConstant()

Description copied from class: Expression

Returns the value of the expression determined in parse time. The default implementation throws UnsupportedOperationException. Subclasses, which return true when Expression.isParseTimeConstant() is called, should override this method.

Overrides:

getParseTimeConstant in class Expression

Returns:

the value determined in parse time

See Also:

Expression.isParseTimeConstant()

getType

public EnumerationType getType()

Description copied from class: Expression

Returns the return type.

Overrides:

getType in class Expression

Returns:

the return type

accept

public <T,E extends Throwable> T accept(ExpressionVisitor<T,E> visitor)
                                 throws E extends Throwable

Description copied from class: Expression

Accepts visitor.

Specified by:

accept in class Expression

Returns:

the result of visit

Throws:

E

E extends Throwable

basicInterpret

protected Object basicInterpret(Interpreter interpreter,
                                InterpreterStackTrace stackTrace)

Description copied from class: Expression

Interpret expression.

Specified by:

basicInterpret in class Expression

Returns:

result of interpretation

getTypeRange

public ASTNode getTypeRange()

Returns the range of the enumeration type.

Returns:

the range of the enumeration type

getConstantRange

public ASTRange getConstantRange()

Returns the range of the constant.

Returns:

the range of the constant
