メソッドの詳細

getFile

public java.lang.String getFile(int fileid)

registerSourceFile

protected int registerSourceFile(java.lang.String file)
Register a new source file. This method is used to implement file inclusion. Each included file gets a uniq identifier (which is the index in the array of source files).
戻り値:
The index of the now registered file.

unregisterSourceFile

protected int unregisterSourceFile(java.lang.String file)
Unregister the source file. This method is used to implement file inclusion. Each included file gets a uniq identifier (which is the index in the array of source files).
戻り値:
The index of the now registered file.

popFile

public boolean popFile()
                throws ParseException

hasMoreInput

public boolean hasMoreInput()
                     throws ParseException

nextChar

public int nextChar()
             throws ParseException

peekChar

public int peekChar()

mark

public Mark mark()

reset

public void reset(Mark mark)

matchesIgnoreCase

public boolean matchesIgnoreCase(java.lang.String string)
                          throws ParseException

matches

public boolean matches(java.lang.String string)
                throws ParseException

advance

public void advance(int n)
             throws ParseException

skipSpaces

public int skipSpaces()
               throws ParseException

skipUntil

public Mark skipUntil(java.lang.String limit)
               throws ParseException
Skip until the given string is matched in the stream. When returned, the context is positioned past the end of the match.
パラメータ:
s - The String to match.
戻り値:
A non-null Mark instance if found, null otherwise.

parseToken

public java.lang.String parseToken(boolean quoted)
                            throws ParseException
Parse a space delimited token. If quoted the token will consume all characters up to a matching quote, otherwise, it consumes up to the first delimiter character.
パラメータ:
quoted - If true accept quoted strings.

parseTagAttributesBean

public org.xml.sax.Attributes parseTagAttributesBean()
                                              throws ParseException
Parse some tag attributes for Beans. The stream is assumed to be positioned right after the tag name. The syntax recognized is:
 tag-attrs := empty | attr-list (">" | "-->" | %>)
 attr-list := empty | av spaces attr-list
 empty     := spaces 
 
Where av is defined by parseAttributeValue.
戻り値:
A Hashtable mapping String instances (variable names) into String instances (variable values).

parseTagAttributes

public org.xml.sax.Attributes parseTagAttributes()
                                          throws ParseException
Parse some tag attributes. The stream is assumed to be positioned right after the tag name. The syntax recognized is:
 tag-attrs := empty | attr-list (">" | "-->" | %>)
 attr-list := empty | av spaces attr-list
 empty     := spaces 
 
Where av is defined by parseAttributeValue.
戻り値:
A Hashtable mapping String instances (variable names) into String instances (variable values).

parseParamTag

public void parseParamTag(java.util.Hashtable into)
                   throws ParseException
Parse PARAM tag attributes into the given hashtable. Parses the PARAM tag as defined by:
 <PARAM tag-attributes %gt;
 
Two special tag attributes are recognized here:
  1. The name attribute,
  2. The value attribute.

パラメータ:
into - Storage for parameter values.

parsePluginParamTag

public void parsePluginParamTag(java.util.Hashtable into)
                         throws ParseException
Parse jsp:param tag attributes into the given hashtable. Parses the jsp:param tag as defined by:
 <jsp:param tag-attributes %gt;
 
Two special tag attributes are recognized here:
  1. The name attribute,
  2. The value attribute.
The resulting name, value pair is stored in the provided hash table.
パラメータ:
into - Storage for parameter values.
