Constructor Detail

AlternateExpression

public AlternateExpression(AbstractRegularExpression expr)

Creates a new AlternateExpression with the given expr as first element

---

AlternateExpression

public AlternateExpression(AbstractRegularExpression expr1,
                           AbstractRegularExpression expr2)

Creates a new AlternateExpression with the given expr as first and second element

---

AlternateExpression

public AlternateExpression(AbstractRegularExpression expr1,
                           AbstractRegularExpression expr2,
                           AbstractRegularExpression expr3)

Creates a new AlternateExpression with the given expr as first, second and third element

---

AlternateExpression

public AlternateExpression()

Creates a new AlternateExpression with no element

Method Detail

add

public void add(AbstractRegularExpression expr)

Add a new child to this AlternateExpression.

---

interpret

public boolean interpret(Context c)
                  throws ParserException

Calls "action" with value=Integer(index of first expression parsed with success, starting from 0).

Specified by:

interpret in class AbstractRegularExpression

---

getExpressionList

public java.util.ArrayList getExpressionList()

Return a list containing every expression in this AlternateExpression

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
