所有已实现的接口:

Walker

public class WalkerPRESERVE
extends java.lang.Object
implements Walker

This Walker implementation walks a list of Content in it's original RAW format. There is no text manipulation, and all content will be returned as the input type. In other words, next() will never be null, and text() will always be null.

WalkerPRESERVE

public WalkerPRESERVE(java.util.List<? extends Content> content)

Create a Walker that preserves all content in its raw state.

参数:

content - the content to walk.

方法详细资料

isAllText

public boolean isAllText()

从接口复制的说明: Walker

If all the content in this walker is empty, or if whatever content is available is Text-like.

Text-like content is considered to be Text, CDATA, EntityRef, or any (potentially mixed) sequence of these types, but no other types.

指定者:

isAllText 在接口中 Walker

返回:

true if there is no content, or all content is Text

hasNext

public boolean hasNext()

从接口复制的说明: Walker

Behaves similarly to to a regular Iterator

指定者:

hasNext 在接口中 Walker

返回:

true if there is more content to be processed

next

public Content next()

从接口复制的说明: Walker

Similar to an Iterator, but null return values need special treatment.

指定者:

next 在接口中 Walker

返回:

the next content to be processed, perhaps null if the next content is re-formatted text of some sort (Text / CDATA).

text

public java.lang.String text()

从接口复制的说明: Walker

If the previous call to next() returned null, then this will return the required text to be processed. Check to see whether this text is CDATA by calling the isCDATA() method.

指定者:

text 在接口中 Walker

返回:

The current text value (null if the previous invocation of next() returned a non-null value).

isCDATA

public boolean isCDATA()

从接口复制的说明: Walker

If the previous next() method returned null, then this will indicate whether the current text() value is CDATA or regular Text.

指定者:

isCDATA 在接口中 Walker

返回:

true if the current text() is valid, and is CDATA.

isAllWhitespace

public boolean isAllWhitespace()

从接口复制的说明: Walker

If all the content is Text-like (Walker.isAllText() returns true), and additionally that any content is either Text or CDATA, and that the values of these Text/CDATA members are all XML Whitespace.

指定者:

isAllWhitespace 在接口中 Walker

返回:

true
