Constructor Detail

CustomConstantExpression

public CustomConstantExpression(ASTInfo astInfo,
                                ConstantInfo info)

Constructs a custom constant expression.

Parameters:

astInfo -

info -

Method Detail

getName

public String getName()

Returns the constant name.

Returns:

the constant name

getModuleName

public String getModuleName()

Returns the name of the module where the constant is declared.

Returns:

the module name

getConstantInfo

public ConstantInfo getConstantInfo()

Returns the constant info object.

Returns:

the constant info

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()

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
