Constructor Detail

ChildrenCollectorFilter

public ChildrenCollectorFilter(String namePattern,
                       Collection<javax.jcr.Item> children,
                       boolean collectNodes,
                       boolean collectProperties,
                       int maxLevel)

Constructs a ChildrenCollectorFilter

Parameters:

namePattern - the pattern which should be applied to the names of the children

children - where the matching children should be added

collectNodes - true, if child nodes should be collected; otherwise false

collectProperties - true, if child properties should be collected; otherwise false

maxLevel - number of hierarchy levels to traverse (e.g. 1 for direct children only, 2 for children and their children, and so on)

ChildrenCollectorFilter

public ChildrenCollectorFilter(String[] nameGlobs,
                       Collection<javax.jcr.Item> children,
                       boolean collectNodes,
                       boolean collectProperties,
                       int maxLevel)

Constructs a ChildrenCollectorFilter

Parameters:

nameGlobs - an array of globbing strings which should be applied to the names of the children

children - where the matching children should be added

collectNodes - true, if child nodes should be collected; otherwise false

collectProperties - true, if child properties should be collected; otherwise false

maxLevel - number of hierarchy levels to traverse (e.g. 1 for direct children only, 2 for children and their children, and so on)
