UnionExpr

public UnionExpr(Expr lhs,
                 Expr rhs)

Method Details

Object evaluate

public @Override Object evaluate(Node context,
                                 int pos,
                                 int len)

clone

public Expr clone(Object context)
Overrides:
clone in interface Expr

matches

public boolean matches(Node context)
Overrides:
matches in interface Pattern

references

public boolean references(QName var)
Overrides:
references in interface Expr

toString

public String toString()
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() and such.

It is typical, but not required, to ensure that this method never completes abruptly with a 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()).

Overrides:
toString in interface Object
Returns:
the String representing this Object, which may be null
See Also:
getClass(), Object.hashCode(), Class.getName(), Integer.toHexString(int)
