Method Detail

getBaseState

public NodeState getBaseState()

Used to evaluate the query (ie. read the existing node types, index definitions), doesn't need to be a secured version of a node state

Returns:

base state of the content tree against which the query runs.

getRoot

public Root getRoot()

Used to create the actual query results from the indexed paths, needs to be a secured version of a tree to take into account ACLs

Returns:

root of the content tree against which the query runs.

getIndexProvider

public QueryIndexProvider getIndexProvider()

Returns:

Index provider for indexes matching the state of the content tree as returned from getBaseState().

getSettings

public QueryEngineSettings getSettings()

getPermissionProvider

public PermissionProvider getPermissionProvider()
