Constructor Detail

DepthItemFilter

public DepthItemFilter()

Default constructor.

DepthItemFilter

public DepthItemFilter(int minDepth,
                       int maxDepth)

Creates a new depth filter for the given depths.

Parameters:

minDepth - the minimal depth

maxDepth - the maximal depth

Method Detail

setMinDepth

public void setMinDepth(String minDepth)

Sets the minimal depth

Parameters:

minDepth - the minimal depth

setMaxDepth

public void setMaxDepth(String maxDepth)

Sets the maximal depth

Parameters:

maxDepth - the maximal depth

matches

public boolean matches(Item item,
                       int depth)
                throws RepositoryException

Checks if the given item matches this filters criteria. The given depth is relative to some invoker related depth and may not reflect the hierarchical depth of the item in the repository. It up to the implementation how to deal with this value. Matches if the given depth is greater or equal the minimum depth and less or equal the maximum depth and if the call to matches(Item) returns true.

Specified by:

matches in interface ItemFilter

Parameters:

item - the item to check

depth - a relative depth.

Returns:

true if this filter matches the criteria; false otherwise.

Throws:

RepositoryException - if an error occurs.

matches

public boolean matches(Item item)
                throws RepositoryException

Returns true. Subclasses can override to implement something useful that is dependant of the depth.

Parameters:

item - the item to match

Returns:

true if the item matches; false otherwise.

Throws:

RepositoryException - if an error occurs.

dump

public void dump(DumpContext ctx,
                 boolean isLast)

Dumps some human readable information using the given context.

Specified by:

dump in interface Dumpable

Parameters:

ctx - the dump context

isLast - specifies if this is the last element to dump on this level
