Example 16 with TimeString

use of org.apache.calcite.util.TimeString in project flink by apache.

the class RexLiteral method appendAsJava.

/**
 * Appends the specified value in the provided destination as a Java string. The value must be
 * consistent with the type, as per {@link #valueMatchesType}.
 *
 * <p>Typical return values:
 *
 * <ul>
 *   <li>true
 *   <li>null
 *   <li>"Hello, world!"
 *   <li>1.25
 *   <li>1234ABCD
 * </ul>
 *
 * @param value Value to be appended to the provided destination as a Java string
 * @param sb Destination to which to append the specified value
 * @param typeName Type name to be used for the transformation of the value to a Java string
 * @param type Type to be used for the transformation of the value to a Java string
 * @param includeType Whether to include the data type in the Java representation
