Method Detail

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

getBase

public final AbstractExpression getBase()

getFilter

public final AbstractExpression getFilter()

setFilter

public final void setFilter(AbstractExpression filter)

accept

public AbstractExpression accept(ExpressionVisitor visitor)

getPrecedence

public int getPrecedence()

Specified by:

getPrecedence in class AbstractExpression

Returns:

19

getRoot

public AbstractExpression getRoot()

Overrides:

getRoot in class AbstractExpression

Returns:

the root of this expression: this will either be a Root(/), a function returning document nodes, or null.

isDocumentOrdered

public boolean isDocumentOrdered()

Overrides:

isDocumentOrdered in class AbstractExpression

Returns:

whether this expression is proven to return results in document order. This method returns true iff all its subs return true, or it has none. Warning: incorrect results may occur if document-ordering is falsely asserted.
