构造器详细资料

ByteOrderMark

public ByteOrderMark(String charsetName,
                     int... bytes)

Construct a new BOM.

参数:

charsetName - The name of the charset the BOM represents

bytes - The BOM's bytes

抛出:

IllegalArgumentException - if the charsetName is null or zero length

IllegalArgumentException - if the bytes are null or zero length

方法详细资料

getCharsetName

public String getCharsetName()

Return the name of the Charset the BOM represents.

返回:

the character set name

length

public int length()

Return the length of the BOM's bytes.

返回:

the length of the BOM's bytes

get

public int get(int pos)

The byte at the specified position.

参数:

pos - The position

返回:

The specified byte

getBytes

public byte[] getBytes()

Return a copy of the BOM's bytes.

返回:

a copy of the BOM's bytes

equals

public boolean equals(Object obj)

Indicates if this BOM's bytes equals another.

覆盖:

equals 在类中 Object

参数:

obj - The object to compare to

返回:

true if the bom's bytes are equal, otherwise false

hashCode

public int hashCode()

Return the hashcode for this BOM.

覆盖:

hashCode 在类中 Object
