Class InDatabaseQueryProcessor

java.lang.Object
  it.sistematica.isharedoc.opencmis.indatabase.query.InDatabaseQueryProcessor

public class InDatabaseQueryProcessor
extends java.lang.Object

A processor for a CMIS query for the In-Database server. During tree traversal conditions are checked against the data contained in the central hash map with all objects. In a first pass one time setup is performed, in a custom walk across the query expression tree an object is checked if it matches. In case of a match it is appended to a list of matching objects.

For each object check if it matches and append it to match-list if it does. We do here our own walking mechanism so that we can pass additional parameters and define the return types.

Parameters:

node - node in where clause

Returns:

true if it matches, false if it not matches

compareTo

protected int compareTo(org.apache.chemistry.opencmis.commons.definitions.PropertyDefinition<?> td,
                        java.lang.Object lValue,
                        java.lang.Object rVal)

translatePattern
