方法详细信息

resolveVariable

public ValueExpression resolveVariable(String variable)

指定者：

类 VariableMapper 中的 resolveVariable

参数：

variable - The variable name

返回：

the ValueExpression assigned to the variable, null if there is no previous assignment to this variable.

setVariable

public ValueExpression setVariable(String variable,
                                   ValueExpression expression)

指定者：

类 VariableMapper 中的 setVariable

参数：

variable - The variable name

expression - The ValueExpression to be assigned to the variable.

返回：

The previous ValueExpression assigned to this variable, null if there is no previouse assignment to this variable.
