Fields

Modifier and Type	Field and Description
Stack<UriContext.LambdaVariables>	allowedLambdaVariables Hold all currently allowed lambda variables As lambda functions can be nested there may be more than one allowed lambda variables at a time while parsing a $filter or $orderby expressions.
ExpandItemImpl	contextExpandItemPath Set within method UriParserBaseVisitor.visitExpandItem(org.apache.olingo.server.core.uri.antlr.UriParserParser.ExpandItemContext ctx) and UriParserBaseVisitor.visitExpandPathExtension(org.apache.olingo.server.core.uri.antlr.UriParserParser.ExpandPathExtensionContext ctx) to allow nodes deeper in the expand tree at UriParserBaseVisitor.visitExpandPathExtension(org.apache.olingo.server.core.uri.antlr.UriParserParser.ExpandPathExtensionContext ctx) appending path segments to the currently processed ExpandItemImpl.
boolean	contextReadingFunctionParameters
boolean	contextReadingQueryPart Set to true if the parser operates on query part.
SelectItemImpl	contextSelectItem Set within method UriParserBaseVisitor.visitSelectItem(org.apache.olingo.server.core.uri.antlr.UriParserParser.SelectItemContext ctx) to allow nodes deeper in the expand tree at UriParserBaseVisitor.visitSelectSegment(org.apache.olingo.server.core.uri.antlr.UriParserParser.SelectSegmentContext ctx) appending path segments to the currently processed SelectItemImpl.
Stack<UriParseTreeVisitor.TypeInformation>	contextTypes Used to stack type information for nested $expand, $filter query options and other cases.
UriInfoImpl	contextUriInfo Stores the currently processed UriInfo objects.
boolean	contextVisitExpandResourcePath Set to true in method UriParseTreeVisitor.visitExpandPath(org.apache.olingo.server.core.uri.antlr.UriParserParser.ExpandPathContext) right before calling UriParseTreeVisitor.readResourcePathSegment(org.apache.olingo.server.core.uri.antlr.UriParserParser.PathSegmentContext) After reading the path the variable is set back to false readResourcePathSegment handles all navigation properties, it depends on the context if key predicates are allowed or not.

allowedLambdaVariables

public Stack<UriContext.LambdaVariables> allowedLambdaVariables

Hold all currently allowed lambda variables As lambda functions can be nested there may be more than one allowed lambda variables at a time while parsing a $filter or $orderby expressions.

contextTypes

public Stack<UriParseTreeVisitor.TypeInformation> contextTypes

Used to stack type information for nested $expand, $filter query options and other cases.

contextExpandItemPath

public ExpandItemImpl contextExpandItemPath

Set within method UriParserBaseVisitor.visitExpandItem(org.apache.olingo.server.core.uri.antlr.UriParserParser.ExpandItemContext ctx) and UriParserBaseVisitor.visitExpandPathExtension(org.apache.olingo.server.core.uri.antlr.UriParserParser.ExpandPathExtensionContext ctx) to allow nodes deeper in the expand tree at UriParserBaseVisitor.visitExpandPathExtension(org.apache.olingo.server.core.uri.antlr.UriParserParser.ExpandPathExtensionContext ctx) appending path segments to the currently processed ExpandItemImpl.

contextVisitExpandResourcePath

public boolean contextVisitExpandResourcePath

Set to true in method UriParseTreeVisitor.visitExpandPath(org.apache.olingo.server.core.uri.antlr.UriParserParser.ExpandPathContext) right before calling UriParseTreeVisitor.readResourcePathSegment(org.apache.olingo.server.core.uri.antlr.UriParserParser.PathSegmentContext) After reading the path the variable is set back to false readResourcePathSegment handles all navigation properties, it depends on the context if key predicates are allowed or not. In case of expand

contextSelectItem

public SelectItemImpl contextSelectItem

Set within method UriParserBaseVisitor.visitSelectItem(org.apache.olingo.server.core.uri.antlr.UriParserParser.SelectItemContext ctx) to allow nodes deeper in the expand tree at UriParserBaseVisitor.visitSelectSegment(org.apache.olingo.server.core.uri.antlr.UriParserParser.SelectSegmentContext ctx) appending path segments to the currently processed SelectItemImpl.

contextUriInfo

public UriInfoImpl contextUriInfo

Stores the currently processed UriInfo objects. There is one URI Info object for the resource path and one for each new first member access within $filter and $orderBy options.

contextReadingFunctionParameters

public boolean contextReadingFunctionParameters

contextReadingQueryPart

public boolean contextReadingQueryPart

Set to true if the parser operates on query part.
