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.
