构造器详细资料

PushbackString

public PushbackString(String input)

参数:

input - Construct a PushbackString with the specified String.

方法详细资料

index

public int index()

从类复制的说明: AbstractPushbackSequence

Get the current index of the PushbackString. Typically used in error messages.

指定者:

index 在接口中 PushbackSequence<Character>

覆盖:

index 在类中 AbstractPushbackSequence<Character>

返回:

The current index of the PushbackSequence.

hasNext

public boolean hasNext()

从类复制的说明: AbstractPushbackSequence

Determine if this sequence has another element.

指定者:

hasNext 在接口中 PushbackSequence<Character>

覆盖:

hasNext 在类中 AbstractPushbackSequence<Character>

返回:

True if there is another element in this sequence. False otherwise.

next

public Character 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 element in the Sequence.

nextHex

public Character 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 element in the Sequence in Hex format (if that makes sense for this Sequence's type).

nextOctal

public Character 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 element in the Sequence in Octal format (if that makes sense for this Sequence's type).

isHexDigit

public static boolean isHexDigit(Character 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(Character 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 Character peek()

从接口复制的说明: PushbackSequence

Return the next element in the Sequence without affecting the current index.

返回:

the next element in the Sequence.

peek

public boolean peek(Character c)

从接口复制的说明: PushbackSequence

Test to see if the next element in the Sequence matches the supplied value without affecting the current index.

参数:

c - The value to match against.

返回:

True if the next element matches the supplied value. False otherwise.

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).
