构造器详细资料

Generate

public Generate()
         throws ParserException

Create a Generate object. Sets up the generation by creating a new Parser pointed at http://www.w3.org/TR/REC-html40/sgml/entities.html with the standard scanners registered.

抛出:

ParserException - ParserException

方法详细资料

translate

public java.lang.String translate(java.lang.String string)

Translate character references. After generating the Translate class we could use it to do this job, but that would involve a bootstrap problem, so this method does the reference conversion for a very tiny subset (enough to understand the w3.org page).

参数:

string - The raw string.

返回:

The string with character references fixed.

gather

public void gather(Node node,
                   java.lang.StringBuffer buffer)

indexOfWhitespace

public int indexOfWhitespace(java.lang.String string,
                             int index)

Find the lowest index of whitespace (space or newline).

参数:

string - The string to look in.

index - Where to start looking.

返回:

-1 if there is no whitespace, the minimum index otherwise.

pack

public java.lang.String pack(java.lang.String string)

Rewrite the comment string. In the sgml table, the comments are of the form:

 -- latin capital letter I with diaeresis,
             U+00CF ISOlat1
 

so we just want to make a one-liner without the spaces and newlines.

参数:

string - The raw comment.

返回:

The single line comment.

pretty

public java.lang.String pretty(java.lang.String string)

Pretty up a comment string.

参数:

string - The comment to operate on.

返回:

The beautiful comment string.

pad

public java.lang.String pad(java.lang.String string,
                            char character,
                            int length)

Pad a string on the left with the given character to the length specified.

参数:

string - The string to pad

character - The character to pad with.

length - The size to pad to.

返回:

The padded string.

unicode

public java.lang.String unicode(java.lang.String string)

Convert the textual representation of the numeric character reference to a character.

参数:

string - The numeric character reference (in quotes).

返回:

The character represented by the numeric character reference.

extract

public void extract(java.lang.String string,
                    java.io.PrintWriter out)

Parse the sgml declaration for character entity reference name, equivalent numeric character reference and a comment. Emit a java hash table 'put' with the name as the key, the numeric character as the value and comment the insertion with the comment.

参数:

string - The contents of the sgml declaration.

out - The sink for output.

sgml

public void sgml(java.lang.String string,
                 java.io.PrintWriter out)

Extract special characters. Scan the string looking for substrings of the form:

 <!ENTITY nbsp   CDATA "&#160;" -- no-break space = non-breaking space, U+00A0 ISOnum -->
 

and emit a java definition for each.

参数:

string - The raw string from w3.org.

out - The sink for output.

parse

public void parse(java.io.PrintWriter out)
           throws ParserException

Pull out text elements from the HTML.

参数:

out - The sink for output.

抛出:

ParserException - ParserException
