Example 6 with DataValueRendererFamily

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

the class TableContentView method getAvailableRenderers.

/**
 * Get the description of all available renderers in a column. The returned
 * array simply contains all description in the
 * <code>DataValueRendererFamily</code> (which should be the default
 * renderer in each column.)
 *
 * @param column the column of interest.
 * @return a new array containing the description of all available renderer
 *         or an empty array to address no available renderer
 * @throws IndexOutOfBoundsException if <code>column</code> violates its
 *         range

Example 7 with DataValueRendererFamily

use of org.knime.core.data.renderer.DataValueRendererFamily 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()}
