Interface Summary

Interface	Description
QNameReferent	An object referencing a QName, either resolved or unresolved.
ResolvedQNameReferent	A QNameReferent referencing a resolved QName.
UnresolvedQNameReferent<T extends ResolvedQNameReferent>	A QNameReferent referencing an unresolved QName.
YangConstantExpr<T>	Common interface for all YANG XPath constant expressions.
YangExpr	Common base interface for all YANG Expression components.
YangPredicateAware	Common interface for YangFilterExpr and YangLocationPath.Step, both of which can contain predicates.
YangXPathExpression	An XPath expression.
YangXPathExpression.QualifiedBound	A Qualified-bound expression.
YangXPathExpression.UnqualifiedBound
YangXPathMathSupport	Interface supporting mathematical operations.
YangXPathParser	Interface for converting a String into a YangXPathExpression.
YangXPathParser.QualifiedBound	A YangXPathParser bound to a YangNamespaceContext, producing Qualified-bound Expressions.
YangXPathParser.UnqualifiedBound	A YangXPathParser bound to a YangNamespaceContext and a default namespace, producing Unqualified-bound Expressions.
YangXPathParserFactory	Factory for creating YangXPathParsers.

YangBooleanConstantExpr	Expressions which evaluate to a logical true or false.
YangFunction	Functions known to a YANG XPath.
YangNaryOperator	YANG XPath binary operator.
YangXPathAxis	XPath evaluation axis, as defined in XPath 1.0.
YangXPathMathMode	YangXPathParser number compliance knobs.
YangXPathNodeType	XPath node type as defined in XPath 1.0.

Package org.opendaylight.yangtools.yang.xpath.api Description

Model of a RFC7950 XPath Expression. This model is namespace-bound to a particular set of models as conveyed by their QNameModules. Function names are bound either to their defining QName, unprefixed functions are bound to YangConstants.RFC6020_YIN_MODULE the same way unprefixed statements are.

The model supports multiple number storage and math operations -- with IEEE754 being the default as per XPath 1.0 specifications, but additional exact operations being available.
