Method Detail

requiresNewNamespace

public boolean requiresNewNamespace()

Overrides:

requiresNewNamespace in class Expression

Returns:

true if the interpretation requires a new namespace

getExpressions

public List<Expression> getExpressions()

Returns the list of child expressions.

Returns:

the list of expressions

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)
                         throws ErrorException

Description copied from class: Expression

Interpret expression.

Specified by:

basicInterpret in class Expression

Returns:

result of interpretation

Throws:

ErrorException

getLastExpression

public Expression getLastExpression()

Returns the last expression.

Returns:

the last expression

getResultExpression

public Expression getResultExpression()

Description copied from class: Expression

Returns the result expression. E.g. for a chained expression, it returns its last child (applied recursively). May return this.

Overrides:

getResultExpression in class Expression

Returns:

the result expression (may be this)

getResultExpressions

public List<Expression> getResultExpressions()

Description copied from class: Expression

Returns the result expression. E.g. for a chained expression, it returns its last child (applied recursively).

Overrides:

getResultExpressions in class Expression

Returns:

the result expressions
