toStringValue

public String toStringValue(XPathContext context)

Evaluate the Expression to a number.

Specified by:

toStringValue in interface Expression

Overrides:

toStringValue in class NodeSetExpression

toBooleanValue

public boolean toBooleanValue(XPathContext context)

Evaluate the Expression to a number.

Specified by:

toBooleanValue in interface Expression

Overrides:

Overrides:

toNodeSet in class ExpressionImpl

toNode

public XPathNode toNode(XPathContext context)

Evaluate the Expression to a XPathNode.

Specified by:

toNode in interface Expression

Overrides:
