Field Detail

formats

protected static final Format[] formats

An array of formats to be tested against the column values. The order in the array is the order in which the formats are tested.

Note that formats DO NOT require a complete match on the source test. For this reason, they are arranged based on the expected ability for the format to be diagnositic. For example, a date such as 4/6/2002 would be interpreted as an integer if you tested the integer format first.
