  ilog.views.graphic.linkpolicy.IlvLinkShapePolicyUtil

public class IlvLinkShapePolicyUtil
extends Object

Utility class for link shape policies.

Since:

JViews 6.0

Field Summary

static int	BUNDLE_POLICY_MODE The mode to be used if a combination of link shape policies is needed that supports the multi link bundling,
static int	CROSSING_POLICY_MODE The mode to be used if a combination of link shape policies is needed that supports the calculation of tunnel or bridge crossings.
static int	ORTHOGONAL_POLICY_MODE The mode to be used if a combination of link shape policies is needed that supports the orthogonal shape constraint.

Method Summary

static IlvCrossingLinkShapePolicy	GetCrossingPolicy(IlvGrapher grapher) Returns the default crossing link shape policy for the crossing aware links of the input grapher.
static IlvLinkShapePolicy	GetLinkShapePolicy(int mode, IlvGrapher grapher) Returns the default link shape policy for the policy aware links of the input grapher that use the input mode.

Method Detail

GetLinkShapePolicy

public static IlvLinkShapePolicy GetLinkShapePolicy(int mode,
                                                    IlvGrapher grapher)

Returns the default link shape policy for the policy aware links of the input grapher that use the input mode. The input mode is a bit-wise OR combination of

• CROSSING_POLICY_MODE
• ORTHOGONAL_POLICY_MODE
• BUNDLE_POLICY_MODE

The default link shape policy is used by all instances of IlvEnhancedPolylineLinkImage that are in the same grapher and have the same mode. The returned link shape policy is actually a combination of link shape policies linked via IlvAbstractLinkShapePolicy.getChildPolicy().

Parameters:

mode - The mode of the links.

grapher - The grapher of the links.

Returns:

The link shape policy that can be used for links of the input grapher.

GetCrossingPolicy

public static IlvCrossingLinkShapePolicy GetCrossingPolicy(IlvGrapher grapher)

Returns the default crossing link shape policy for the crossing aware links of the input grapher. The default crossing link shape policy is used by all instances of IlvEnhancedPolylineLinkImage that are in the same grapher and have crossings enabled.

Parameters:

grapher - The grapher of the links.

Returns:

The crossing link shape policy that can be used for links of the input grapher.
