Method Summary

Modifier and Type	Method	Description
void	fill(String arg)	负责填充该参数节点,覆写该方法需要实现对接受参数arg的验证以及解析成为对应类型T的结果 当验证失败或者解析失败,请调用IParamNode.error(String)方法标记错误.形如this.error()
<E> E	get()	获取已被IParamNode.fill(String)填充后的节点值,会自动转型为接受类型E,不会判断是否能成功转型 有可能抛出ClassCastException
ParamList	getParent()	获取该节点所属ParamList
boolean	hasResult()	该节点是否已经得到结果 该方法返回值为false时,将会一直重复对该节点执行填充IParamNode.fill(String)直到该方法返回true或者命令输入参数用完
boolean	isOptional()	该命令节点是否为可选值,可选值不一定需要被填充IParamNode.fill(String)
void	reset()	将节点重置回初始化状态,以待下次填充IParamNode.fill(String)

fill

public void fill(String arg)

Description copied from interface: IParamNode

负责填充该参数节点,覆写该方法需要实现对接受参数arg的验证以及解析成为对应类型T的结果
当验证失败或者解析失败,请调用IParamNode.error(String)方法标记错误.形如this.error()

Specified by:

fill in interface IParamNode<Void>

Parameters:

arg - the arg

get

public <E> E get()

Description copied from interface: IParamNode

获取已被IParamNode.fill(String)填充后的节点值,会自动转型为接受类型E,不会判断是否能成功转型
有可能抛出ClassCastException

Specified by:

get in interface IParamNode<Void>

reset

public void reset()

Description copied from interface: IParamNode

将节点重置回初始化状态,以待下次填充IParamNode.fill(String)

Specified by:

reset in interface IParamNode<Void>

getParent

public ParamList getParent()

Description copied from interface: IParamNode

获取该节点所属ParamList

Specified by:

getParent in interface IParamNode<Void>

Returns:

the parent

hasResult

public boolean hasResult()

Description copied from interface: IParamNode

该节点是否已经得到结果
该方法返回值为false时,将会一直重复对该节点执行填充IParamNode.fill(String)直到该方法返回true或者命令输入参数用完

Specified by:

hasResult in interface IParamNode<Void>

isOptional

public boolean isOptional()

Description copied from interface: IParamNode

该命令节点是否为可选值,可选值不一定需要被填充IParamNode.fill(String)

Specified by:

isOptional in interface IParamNode<Void>
