Member Function Documentation

int te::graph::LayerRenderer::checkEdgeGeometryProperty ( te::graph::AbstractGraph *  g )

protected

Verify if the graph layer has a geometry to define the edges elements.

int te::graph::LayerRenderer::checkVertexGeometryProperty ( te::graph::AbstractGraph *  g )

protected

Verify if the graph layer has a geometry to define the vertexs elements.

void te::graph::LayerRenderer::configDefaultLine ( te::map::Canvas *  canvas )

protected

Configs the canvas with default values for line styles.

void te::graph::LayerRenderer::configDefaultPoint ( te::map::Canvas *  canvas )

protected

Configs the canvas with default values for point styles.

void te::graph::LayerRenderer::configLoopPoint ( te::map::Canvas *  canvas )

protected

Configs the canvas with default values for point styles.

virtual void te::graph::LayerRenderer::draw ( te::map::AbstractLayer *  layer, te::map::Canvas *  canvas, const te::gm::Envelope &  bbox, int  srid, const double &  scale, bool *  cancel  )

virtual

It draws the layer geographic objects in the given canvas using the informed SRS.

The informed bounding box (bbox) is used to constraint the Layer objects to be drawn. The bbox coordinates must be in the Spatial Reference System given by srid.

Parameters

layer	The layer to be rendered.
canvas	The canvas were the layer objects will be drawn.
bbox	The interest area to render the map.
srid	The SRS to be used to draw the layer objects.

Implements te::map::AbstractRenderer.

void te::graph::LayerRenderer::drawDataSourceGraph ( te::graph::AbstractGraph *  g, te::map::Canvas *  canvas, const te::gm::Envelope &  bbox  )

protected

void te::graph::LayerRenderer::drawMemoryGraph ( te::graph::AbstractGraph *  g, te::map::Canvas *  canvas, const te::gm::Envelope &  bbox, int  srid  )

protected

LayerRenderer& te::graph::LayerRenderer::operator= ( const LayerRenderer &  rhs )

private

Assignment operator not allowed.

Parameters

rhs	The right-hand-side copy that would be used to copy from.

Returns

A reference to this object.
