org.apache.poi.ss.formula.functions.Substitute

All Implemented Interfaces:

Function, Function3Arg, Function4Arg

public final class Substitute
extends java.lang.Object

An implementation of the SUBSTITUTE function:

Substitutes text in a text string with new text, some number of times.

(SUBSTITUTE 函数的一个实现：用新文本多次替换文本字符串中的文本。)

Method Detail

evaluate

public ValueEval evaluate(int srcRowIndex,
                          int srcColumnIndex,
                          ValueEval arg0,
                          ValueEval arg1,
                          ValueEval arg2)

Description copied from interface: Function3Arg

see Function.evaluate(ValueEval[], int, int) (见 Function.evaluate(ValueEval[], int, int))

evaluate

public ValueEval evaluate(int srcRowIndex,
                          int srcColumnIndex,
                          ValueEval arg0,
                          ValueEval arg1,
                          ValueEval arg2,
                          ValueEval arg3)

Description copied from interface: Function4Arg

see Function.evaluate(ValueEval[], int, int) (见 Function.evaluate(ValueEval[], int, int))

evaluate

public final ValueEval evaluate(ValueEval[] args,
                                int srcRowIndex,
                                int srcColumnIndex)

Specified by:

evaluate in interface Function (在接口函数中求值)

Parameters:

args - the evaluated function arguments. Empty values are represented with BlankEval or MissingArgEval, never null. (args - 评估的函数参数。空值用 BlankEval 或 MissingArgEval 表示，绝不为 null。)

srcRowIndex - row index of the cell containing the formula under evaluation (srcRowIndex - 包含计算公式的单元格的行索引)

srcColumnIndex - column index of the cell containing the formula under evaluation (srcColumnIndex - 包含正在评估的公式的单元格的列索引)

Returns:

The evaluated result, possibly an ErrorEval, never null. Note - Excel uses the error code #NUM! instead of IEEE NaN, so when numeric functions evaluate to Double.NaN be sure to translate the result to ErrorEval.NUM_ERROR. (评估结果，可能是 ErrorEval，绝不为空。注意 - Excel 使用错误代码 #NUM！而不是 IEEE NaN，因此当数值函数计算为 Double.NaN 时，请务必将结果转换为 ErrorEval.NUM_ERROR。)
