CharSequenceInputStream

public CharSequenceInputStream(CharSequence cs,
                               Charset charset,
                               int bufferSize)

Constructor.

参数:

cs - the input character sequence

charset - the character set name to use

bufferSize - the buffer size to use.

抛出:

IllegalArgumentException - if the buffer is not large enough to hold a complete character

CharSequenceInputStream

public CharSequenceInputStream(CharSequence cs,
                               String charset,
                               int bufferSize)

Constructor, calls CharSequenceInputStream(CharSequence, Charset, int).

参数:

cs - the input character sequence

charset - the character set name to use

bufferSize - the buffer size to use.

抛出:

IllegalArgumentException - if the buffer is not large enough to hold a complete character
