Constructor Detail

IsNodeFilter

public IsNodeFilter()

Default constructor.

IsNodeFilter

public IsNodeFilter(boolean polarity,
                    int minDepth,
                    int maxDepth)

Creates a new node item filter.

Parameters:

polarity - the polarity of this filter. if true it matches nodes, if false it matches properties.

minDepth - the minimum depth

maxDepth - the maximum depth

DepthItemFilter

IsNodeFilter

public IsNodeFilter(boolean polarity)

Creates a new node item filter

Parameters:

polarity - the polarity of this filter. if true it matches nodes, if false it matches properties.

Method Detail

setPolarity

public void setPolarity(java.lang.String polarity)

Sets the polarity of this filter. If set to true this filter matches nodes otherwise properties.

Parameters:

polarity - the polarity

setIsNode

public void setIsNode(java.lang.String polarity)

Sets the polarity of this filter. If set to true this filter matches nodes otherwise properties.

Parameters:

polarity - the polarity

matches

public boolean matches(Item item)
                throws RepositoryException

Returns true. Subclasses can override to implement something useful that is dependant of the depth. Returns true if the item is a node and the polarity is positive (true).

Overrides:

matches in class DepthItemFilter

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

Overrides:

dump in class DepthItemFilter

Parameters:

ctx - the dump context

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