accept

public AbstractExpression accept(ExpressionVisitor visitor)

toString

public void toString(StringBuilder buf)

Description copied from class: AbstractExpression

Each subclass must implement the toString(StringBuilder) method by rendering itself as a syntatically valid XPath/XQuery expression in the given buffer.

Specified by:

toString in class AbstractExpression

getCondition

public final AbstractExpression getCondition()

getTrueAction

public final AbstractExpression getTrueAction()

getFalseAction

public final AbstractExpression getFalseAction()

getPrecedence

public int getPrecedence()

Specified by:

getPrecedence in class AbstractExpression

Returns:

a number indicating the *outer* precedence of this expression. Expressions with lower precedence numbers have lower precedence, ie bind more loosely, than expressions with higher precedence. Expressions with no sub-expressions are assigned a high precedence. Complex expressions can be seen as having an inner and an outer precedence; for example function call expressions behave as a comma with regard to their sub-expressions, the arguments, and like parentheses to their enclosing expression.
