构造器详细资料

PrototypicalNodeFactory

public PrototypicalNodeFactory()

Create a new factory with all tags registered. Equivalent to PrototypicalNodeFactory(false).

PrototypicalNodeFactory

public PrototypicalNodeFactory(boolean empty)

Create a new factory.

参数:

empty - If true, creates an empty factory, otherwise create a new factory with all tags registered.

PrototypicalNodeFactory

public PrototypicalNodeFactory(Tag tag)

Create a new factory with the given tag as the only registered tag.

参数:

tag - The single tag to register in the otherwise empty factory.

PrototypicalNodeFactory

public PrototypicalNodeFactory(Tag[] tags)

Create a new factory with the given tags registered.

参数:

tags - The tags to register in the otherwise empty factory.

方法详细资料

put

public Tag put(java.lang.String id,
               Tag tag)

Adds a tag to the registry.

参数:

id - The name under which to register the tag. For proper operation, the id should be uppercase so it will be matched by a Map lookup.

tag - The tag to be returned from a createTagNode(org.htmlparser.lexer.Page, int, int, java.util.Vector) call.

返回:

The tag previously registered with that id if any, or null if none.

get

public Tag get(java.lang.String id)

Gets a tag from the registry.

参数:

id - The name of the tag to return.

返回:

The tag registered under the id name, or null if none.

remove

public Tag remove(java.lang.String id)

Remove a tag from the registry.

参数:

id - The name of the tag to remove.

返回:

The tag that was registered with that id, or null if none.

clear

public void clear()

Clean out the registry.

getTagNames

public java.util.Set getTagNames()

Get the list of tag names.

返回:

The names of the tags currently registered.

registerTag

public void registerTag(Tag tag)

Register a tag. Registers the given tag under every id that the tag has (i.e. all names returned by tag.getIds().

For proper operation, the ids are converted to uppercase so they will be matched by a Map lookup.

参数:

tag - The tag to register.

unregisterTag

public void unregisterTag(Tag tag)

Unregister a tag. Unregisters the given tag from every id the tag has.

The ids are converted to uppercase to undo the operation of registerTag.

参数:

tag - The tag to unregister.

registerTags

public PrototypicalNodeFactory registerTags()

Register all known tags in the tag package. Registers tags from the tag package by calling registerTag().

返回:

'this' nodefactory as a convenience.

getTextPrototype

public Text getTextPrototype()

Get the object that is cloned to generate text nodes.

返回:

The prototype for Text nodes.

另请参阅:

setTextPrototype(org.htmlparser.Text)

setTextPrototype

public void setTextPrototype(Text text)

Set the object to be used to generate text nodes.

参数:

text - The prototype for Text nodes. If null the prototype is set to the default (TextNode).

getTextPrototype()

getRemarkPrototype

public Remark getRemarkPrototype()

Get the object that is cloned to generate remark nodes.

返回:

The prototype for Remark nodes.

另请参阅:

setRemarkPrototype(org.htmlparser.Remark)

setRemarkPrototype

public void setRemarkPrototype(Remark remark)

Set the object to be used to generate remark nodes.

参数:

remark - The prototype for Remark nodes. If null the prototype is set to the default (RemarkNode).

getRemarkPrototype()

getTagPrototype

public Tag getTagPrototype()

Get the object that is cloned to generate tag nodes. Clones of this object are returned from createTagNode(org.htmlparser.lexer.Page, int, int, java.util.Vector) when no specific tag is found in the list of registered tags.

返回:

The prototype for Tag nodes.

另请参阅:

setTagPrototype(org.htmlparser.Tag)

setTagPrototype

public void setTagPrototype(Tag tag)

Set the object to be used to generate tag nodes. Clones of this object are returned from createTagNode(org.htmlparser.lexer.Page, int, int, java.util.Vector) when no specific tag is found in the list of registered tags.

参数:

tag - The prototype for Tag nodes. If null the prototype is set to the default (TagNode).

createStringNode

public Text createStringNode(Page page,
                             int start,
                             int end)

Create a new string node.

指定者:

createStringNode 在接口中 NodeFactory

参数:

page - The page the node is on.

start - The beginning position of the string.

end - The ending position of the string.

返回:

A text node comprising the indicated characters from the page.

createRemarkNode

public Remark createRemarkNode(Page page,
                               int start,
                               int end)

Create a new remark node.

指定者:

createRemarkNode 在接口中 NodeFactory

参数:

page - The page the node is on.

start - The beginning position of the remark.

end - The ending positiong of the remark.

返回:

createTagNode

public Tag createTagNode(Page page,
                         int start,
                         int end,
                         java.util.Vector attributes)

Create a new tag node. Note that the attributes vector contains at least one element, which is the tag name (standalone attribute) at position zero. This can be used to decide which type of node to create, or gate other processing that may be appropriate.
