Class ParsedFhirPath

java.lang.Object

ca.uhn.fhir.jpa.patch.ParsedFhirPath

public class ParsedFhirPath
extends Object

This class creates and contains a parsed fhirpath. - It does not *validate* said fhir path (it might not be a valid path at all). It is only used for parsing convenience.

Method Details

getRawPath

public String getRawPath()

getHead

public ParsedFhirPath.FhirPathNode getHead()

setTail

public void setTail(ParsedFhirPath.FhirPathNode theTail)

getTail

public ParsedFhirPath.FhirPathNode getTail()

setEndsWithFilter

public void setEndsWithFilter(boolean theEndsWithFilter)

endsWithAFilter

public boolean endsWithAFilter()

setEndsWithAnIndex

public void setEndsWithAnIndex(boolean theEndsWithAnIndex)

endsWithAnIndex

public boolean endsWithAnIndex()

endsWithFilterOrIndex

public boolean endsWithFilterOrIndex()

getFirstNode

public ParsedFhirPath.FhirPathNode getFirstNode(Predicate<ParsedFhirPath.FhirPathNode> thePred)

getTopLevelPathFromTo

public String getTopLevelPathFromTo(Predicate<ParsedFhirPath.FhirPathNode> theFromPred,
 Predicate<ParsedFhirPath.FhirPathNode> theToPred)

Returns the top level path from the provided from predicate to the provided to predicate Top level means it will not delve into subpaths. So, given the example Patient.name.where(given.startsWith('homer')).first() you cannot construct a path from "Patient" to "given"

Parameters:

theFromPred - the inclusive beginning predicate

theToPred - the exclusive ending predicate

Returns:

getContainingPath

public String getContainingPath()

Returns the fhir path up to the last element. If there is a filter, it will return the element before the last (filtered) element.

getAllNodesWithPred

public void getAllNodesWithPred(List<ParsedFhirPath.FhirPathNode> theNodes,
 Predicate<ParsedFhirPath.FhirPathNode> thePred)

Returns all nodes, ordered, filtering by the provided predicate

getFinalPathNode

public ParsedFhirPath.FhirPathNode getFinalPathNode()

Returns the last non-function, non-value node

getLastElementName

public String getLastElementName()

Returns the final non-function node value in the expression. Eg: Patient.name.given -> returns "given" Patient.name.where(given.startsWith("John")) -> returns "given"

getNodes

public List<ParsedFhirPath.FhirPathNode> getNodes(Predicate<ParsedFhirPath.FhirPathNode> thePred)

Retrieve a list of nodes that meet the given predicate. These nodes may or may not be siblings, but it will not include children of nodes (ie, only top-level nodes).

parse

public static ParsedFhirPath parse(String theFullPath)

Create a ParsedFhirPath from a raw string.
