java.text.ParsePosition

public class ParsePosition
extends Object

ParsePosition is a simple class used by Format and its subclasses to keep track of the current position during parsing. The parseObject method in the various Format classes requires a ParsePosition object as an argument.

By design, as you parse through a string with different formats, you can use the same ParsePosition, since the index parameter records the current position.

构造器详细资料

ParsePosition

public ParsePosition(int index)

Create a new ParsePosition with the given initial index.

参数:

index - initial index

方法详细资料

getIndex

public int getIndex()

Retrieve the current parse position. On input to a parse method, this is the index of the character at which parsing will begin; on output, it is the index of the character following the last character parsed.

返回:

the current parse position

setIndex

public void setIndex(int index)

Set the current parse position.

参数:

index - the current parse position

setErrorIndex

public void setErrorIndex(int ei)

Set the index at which a parse error occurred. Formatters should set this before returning an error code from their parseObject method. The default value is -1 if this is not set.

参数:

ei - the index at which an error occurred

从以下版本开始:

1.2

getErrorIndex

public int getErrorIndex()

Retrieve the index at which an error occurred, or -1 if the error index has not been set.

返回:

the index at which an error occurred

从以下版本开始:

1.2

equals

public boolean equals(Object obj)

Overrides equals

覆盖:

equals 在类中 Object

参数:

obj - the reference object with which to compare.

返回:

true if this object is the same as the obj argument; false otherwise.

Object.hashCode(), HashMap

hashCode

public int hashCode()

Returns a hash code for this ParsePosition.

覆盖:

hashCode 在类中 Object

返回:

a hash code value for this object

另请参阅:

Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

toString

public String toString()

Return a string representation of this ParsePosition.

覆盖:

toString 在类中 Object

返回:

a string representation of this object
