Examples with DefaultDataValueRendererFamily org.knime.core.data.renderer.DefaultDataValueRendererFamily used on opensource projects

Example 1 with DefaultDataValueRendererFamily

use of org.knime.core.data.renderer.DefaultDataValueRendererFamily in project knime-core by knime.

the class ExtensibleUtilityFactory method getRendererFamily.

/**
 * {@inheritDoc}
 */
@Override
protected final DataValueRendererFamily getRendererFamily(final DataColumnSpec spec) {
    readRenderersFromExtensionPoint();
    DataValueRenderer[] renderers = new DataValueRenderer[m_renderers.size()];
    int i = 0;
    readPreferredRendererFromPreferences();
    DataValueRendererFactory prefRenderer = getPreferredRenderer();
    DataValueRendererFactory defaultRenderer = getDefaultRenderer();
    if (prefRenderer != null) {
        renderers[i++] = prefRenderer.createRenderer(spec);
    } else if (defaultRenderer != null) {
        renderers[i++] = defaultRenderer.createRenderer(spec);
    }
    for (DataValueRendererFactory fac : m_renderers.values()) {
        if (fac.equals(prefRenderer) || ((prefRenderer == null) && fac.equals(defaultRenderer))) {
            continue;
        }
        renderers[i++] = fac.createRenderer(spec);
    }
    return new DefaultDataValueRendererFamily(renderers);
}

Example 2 with DefaultDataValueRendererFamily

use of org.knime.core.data.renderer.DefaultDataValueRendererFamily in project knime-core by knime.

the class DataType method getRenderer.

/**
 * Returns a family of all renderers that are available for this <code>DataType</code>. The returned
 * {@link org.knime.core.data.renderer.DataValueRendererFamily} will contain all renderers that are supported or
 * available through the compatible {@link org.knime.core.data.DataValue} interfaces. If no renderer was declared by
 * the {@link org.knime.core.data.DataValue} interfaces, this method will make sure that at least a default renderer
 * (using the {@link DataCell#toString()} method) is returned.
 *
 * <p>
 * The {@link DataColumnSpec} is passed to all renderer families retrieved from the underlying
 * {@link UtilityFactory}. Most of the renderer implementations won't need column domain information but some do.
 * For instance a class that renders the double value in the column according to the minimum/maximum values in the
 * {@link DataColumnDomain}.
 *
 * @param spec the column spec to the column for which the renderer will be used
 * @return a family of all renderers that are available for this <code>DataType</code>
 * @deprecated Replaced by {@link #getRendererFactories()}
