Examples with SystemProperty org.apache.ignite.SystemProperty used on opensource projects

Example 1 with SystemProperty

use of org.apache.ignite.SystemProperty in project ignite by apache.

the class CommandLineStartup method printSystemPropertiesInfo.

/**
 * Prints properties info to console.
 */
private static void printSystemPropertiesInfo() {
    Map<String, Field> props = new TreeMap<>();
    int maxLength = 0;
    for (Class<?> cls : PROPS_CLS) {

                    props.put(name, field);
                } catch (IgniteCheckedException ignored) {
                // No-op.
