Example 12 with BinaryData

use of org.hsqldb_voltpatches.types.BinaryData in project voltdb by VoltDB.

the class ExpressionValue method voltMutateToBigintType.

// A VoltDB extension to allow X'..' as numeric literals
/**
     * Given a ExpressionValue that is a VARBINARY constant,
     * convert it to a BIGINT constant.  Returns true for a
     * successful conversion and false otherwise.
     *
     * For more details on how the conversion is performed, see BinaryData.toLong().
     *
     * @param parent      Reference of parent expression
     * @param childIndex  Index of this node in parent
     * @return true for a successful conversion and false otherwise.
