方法详细资料

next

public Integer next()

从接口复制的说明: PushbackSequence

Return the next element in the Sequence and increment the current index.

返回:

The next value in this Sequence, as an Integer.

nextHex

public Integer nextHex()

从接口复制的说明: PushbackSequence

Return the next element in the Sequence in Hex format and increment the current index.

返回:

The next value in this Sequence, as an Integer if it is a hex digit. Null otherwise.

nextOctal

public Integer nextOctal()

从接口复制的说明: PushbackSequence

Return the next element in the Sequence in Octal format and increment the current index.

返回:

The next value in this Sequence, as an Integer if it is an octal digit. Null otherwise.

isHexDigit

public static boolean isHexDigit(Integer c)

Returns true if the parameter character is a hexidecimal digit 0 through 9, a through f, or A through F.

参数:

c -

返回:

true if it is a hexidecimal digit, false otherwise.

isOctalDigit

public static boolean isOctalDigit(Integer c)

Returns true if the parameter character is an octal digit 0 through 7.

参数:

c -

返回:

true if it is an octal digit, false otherwise.

peek

public Integer peek()

Return the next codePoint without affecting the current index.

返回:

the next codePoint

peek

public boolean peek(Integer c)

Test to see if the next codePoint is a particular value without affecting the current index.

参数:

c -

返回:

if the next value is equal to the supplied value.

mark

public void mark()

Mark the location of the current index.

reset

public void reset()

Set the index back to the last marked location.

remainder

public String remainder()

Not at all sure what this method is intended to do. There is a line in HTMLEntityCodec that said calling this method is a "kludge around PushbackString..."

返回:

Return the remaining portion of the sequence, with any pushback appended to the front (if any).
