Constructor Detail

NodeTypePredicate

public NodeTypePredicate(String nodeType,
                         boolean respectSupertype,
                         int minDepth,
                         int maxDepth)

Creates a new node type filter.

Parameters:

nodeType - the node type to filter on

respectSupertype - indicates if supertype should be respected

minDepth - the minimal depth

maxDepth - the maximal depth

NodeTypePredicate

public NodeTypePredicate(String nodeType,
                         boolean respectSupertype)

Creates a new node type filter.

Parameters:

nodeType - the node type to filter on

respectSupertype - indicates if supertype should be respected

Method Detail

matches

protected boolean matches(Item item)
                   throws RepositoryException

Returns true if the item is a node and if the configured nodetype is equal to the primary type of the node. if supertypes are respected it also returns true if the items nodetype extends from the configured node type (Node.isNodeType() check).

Overrides:

matches in class DepthPredicate

Parameters:

item - the item to match

Returns:

true if the item matches; false otherwise.

Throws:

RepositoryException - if an error occurs.
