Method Detail

formatValue

public void formatValue(java.lang.StringBuffer toAppendTo,
                        java.lang.Object value)

Format a value according the format string.

NOTE: this method must be thread safe! In particular, if it uses a Format instance that is not thread safe, i.e. DateFormat, this method must be synchronized, either on the method, if the format is a final property, or on the format instance itself. (根据格式字符串格式化一个值。注意：此方法必须是线程安全的！特别是，如果它使用非线程安全的 Format 实例，即 DateFormat，则此方法必须在方法上同步，如果格式是最终属性，或者在格式实例本身上同步。)

Specified by:

formatValue in class CellFormatter (类 CellFormatter 中的 formatValue)

Parameters:

toAppendTo - The buffer to append to. (toAppendTo - 要附加到的缓冲区。)

value - The value to format. (value - 要格式化的值。)

simpleValue

public void simpleValue(java.lang.StringBuffer toAppendTo,
                        java.lang.Object value)

Format a value according to the type, in the most basic way.

NOTE: this method must be thread safe! In particular, if it uses a Format instance that is not thread safe, i.e. DateFormat, this method must be synchronized, either on the method, if the format is a final property, or on the format instance itself.

For a date, this is "mm/d/y".

(以最基本的方式根据类型格式化一个值。注意：此方法必须是线程安全的！特别是，如果它使用非线程安全的 Format 实例，即 DateFormat，则必须在方法上同步此方法，如果格式是最终属性，或者在格式实例本身上同步。对于日期，这是“mm/d/y”。)

Specified by:

simpleValue in class CellFormatter (CellFormatter 类中的 simpleValue)

Parameters:

toAppendTo - The buffer to append to. (toAppendTo - 要附加到的缓冲区。)

value - The value to format. (value - 要格式化的值。)
