Constructor Detail

ChildrenCollectorFilter

public ChildrenCollectorFilter(java.lang.String namePattern,
                               java.util.Collection<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(java.lang.String[] nameGlobs,
                               java.util.Collection<Item> children,
                               boolean collectNodes,

                               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)
