Class ThresholdSource

java.lang.Object

org.licas.service.link.ThresholdSource

public class ThresholdSource
extends java.lang.Object

This class stores values relating to a linked source, stored in a Thresholds structure. Each reference in the Thresholds structure needs certain information about each source it is linking with, including the current link value, or the source reference itself, including probably a URI description. As this is different for each source, the information is stored here.

Constructor Detail

ThresholdSource

public ThresholdSource(Thresholds thisParent)
                throws java.lang.Exception

Creates a new instance of ThresholdSource. The maximum allowed negative entries is set to Const.DEFAULTMAXNEGATIVE. The value itself is a special case however and not generally used.

Parameters:

thisParent - the parent thresholds structure.

Throws:

java.lang.Exception - any error.

ThresholdSource

public ThresholdSource(int thisNegativeMax,
                       Thresholds thisParent)
                throws java.lang.Exception

Creates a new instance of ThresholdSource.

Parameters:

thisNegativeMax - the maximum number of negative allowed entries.

thisParent - the parent thresholds structure.

Throws:

java.lang.Exception - any error.

hasNegative

public boolean hasNegative(java.util.ArrayList<java.lang.Object> theNodes)
                    throws java.lang.Exception

Return true if any of the negative concepts are stored with the link.

Parameters:

theNodes - the node sources to add as negative, in relation to concepts(parts).

Returns:

true if any concepts in the list are at the link level in this structure.

Throws:

java.lang.Exception - any error.

addNegative

public void addNegative(java.util.ArrayList<java.lang.Object> theNodes)
                 throws java.lang.Exception
