Interface AnchorShape

public interface AnchorShape

Represents an anchor shape which is rendered at the source and the target point of a connection widget where the shape is used. The same instance of a shape could be shared by multiple connection widgets.

Field Summary

static AnchorShape NONE
          The empty anchor shape.

static AnchorShape TRIANGLE_FILLED
          The filled-triangle anchor shape.

static AnchorShape TRIANGLE_HOLLOW
          The hollow-triangle anchor shape.

static AnchorShape TRIANGLE_OUT
          The output-triangle anchor shape.

Method Summary

double getCutDistance()
          Returns a distance by which a line at particular source or target point should be cut (not rendered).

int getRadius()
          Returns a radius of a shape that the shape used for rendering.

boolean isLineOriented()
          Returns whether the shape is oriented by the line path of a connection.

void paint(Graphics2D graphics, boolean source)
          Renders the shape into a graphics instance

Field Summary
`static AnchorShape`	`NONE` The empty anchor shape.
`static AnchorShape`	`TRIANGLE_FILLED` The filled-triangle anchor shape.
`static AnchorShape`	`TRIANGLE_HOLLOW` The hollow-triangle anchor shape.
`static AnchorShape`	`TRIANGLE_OUT` The output-triangle anchor shape.

Method Summary
`double`	`getCutDistance()` Returns a distance by which a line at particular source or target point should be cut (not rendered).
`int`	`getRadius()` Returns a radius of a shape that the shape used for rendering.
`boolean`	`isLineOriented()` Returns whether the shape is oriented by the line path of a connection.
`void`	`paint(Graphics2D graphics, boolean source)` Renders the shape into a graphics instance

Field Detail

NONE

static final AnchorShape NONE

The empty anchor shape.

TRIANGLE_HOLLOW

static final AnchorShape TRIANGLE_HOLLOW

The hollow-triangle anchor shape.

TRIANGLE_FILLED

static final AnchorShape TRIANGLE_FILLED

The filled-triangle anchor shape.

TRIANGLE_OUT

static final AnchorShape TRIANGLE_OUT

The output-triangle anchor shape.

Method Detail

isLineOriented

boolean isLineOriented()

Returns whether the shape is oriented by the line path of a connection.

Returns:: true if it is line-oriented

getRadius

int getRadius()

Returns a radius of a shape that the shape used for rendering.

Returns:: the radius

getCutDistance

double getCutDistance()

Returns a distance by which a line at particular source or target point should be cut (not rendered). This is used for hollow-triangle shapes, to not paint the connection-line within the triangle.

Returns:: the cut distance in pixels; if positive, then the line is cut by specified number of pixels, the line could be cut by radius pixels only; if 0.0, then the line is not cut; if negative, then the line is extended by specified number of pixels, the line could be extended by radius pixels only

paint

void paint(Graphics2D graphics,
           boolean source)

Renders the shape into a graphics instance

Parameters:: graphics - the graphics; source - true, if the shape is used for a source point; false if the shape is used for a target point.
