public class ElemNumber

extends ElemTemplateElement

Implement xsl:number.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

Field Detail

m_countMatchPattern

public XPath m_countMatchPattern

Only nodes are counted that match this pattern.

m_fromMatchPattern

public XPath m_fromMatchPattern

Specifies where to count from. For level="single" or level="multiple": Only ancestors that are searched are those that are descendants of the nearest ancestor that matches the from pattern. For level="any: Only nodes after the first node before the current node that match the from pattern are considered.

m_level

public int m_level

When level="single", it goes up to the first node in the ancestor-or-self axis that matches the count pattern, and constructs a list of length one containing one plus the number of preceding siblings of that ancestor that match the count pattern. If there is no such ancestor, it constructs an empty list. If the from attribute is specified, then the only ancestors that are searched are those that are descendants of the nearest ancestor that matches the from pattern. Preceding siblings has the same meaning here as with the preceding-sibling axis. When level="multiple", it constructs a list of all ancestors of the current node in document order followed by the element itself; it then selects from the list those nodes that match the count pattern; it then maps each node in the list to one plus the number of preceding siblings of that node that match the count pattern. If the from attribute is specified, then the only ancestors that are searched are those that are descendants of the nearest ancestor that matches the from pattern. Preceding siblings has the same meaning here as with the preceding-sibling axis. When level="any", it constructs a list of length one containing the number of nodes that match the count pattern and belong to the set containing the current node and all nodes at any level of the document that are before the current node in document order, excluding any namespace and attribute nodes (in other words the union of the members of the preceding and ancestor-or-self axes). If the from attribute is specified, then only nodes after the first node before the current node that match the from pattern are considered.

m_valueExpr

public XPath m_valueExpr

The value attribute contains an expression. The expression is evaluated and the resulting object is converted to a number as if by a call to the number function.

m_format_avt

public AVT m_format_avt

m_lang_avt

public AVT m_lang_avt

m_lettervalue_avt

public AVT m_lettervalue_avt

m_groupingSeparator_avt

public AVT m_groupingSeparator_avt

m_groupingSize_avt

public AVT m_groupingSize_avt

int2singlealphaCount

                                                char[] table)

Convert a long integer into alphabetic counting, in other words count using the sequence A B C ... Z.

Parameters:

val - Value to convert -- must be greater than zero.

table - a table containing one character for each digit in the radix

Returns:

String representing alpha count of number.

See Also:

Note that the radix of the conversion is inferred from the size of the table.

Convert a long integer into alphabetic counting, in other words count using the sequence A B C ... Z AA AB AC.... etc.

Parameters:

val - Value to convert -- must be greater than zero.

table - a table containing one character for each digit in the radix

Returns:

String representing alpha count of number.

See Also:

Note that the radix of the conversion is inferred from the size of the table.

tradAlphaCount

protected java.lang.String tradAlphaCount(int val,
                                          XSLTResourceBundle thisBundle)

Convert a long integer into traditional alphabetic counting, in other words count using the traditional numbering.

Parameters:

val - Value to convert -- must be greater than zero.

table - a table containing one character for each digit in the radix

Returns:

String representing alpha count of number.

See Also:

Note that the radix of the conversion is inferred from the size of the table.

long2roman

protected java.lang.String long2roman(long val,
                                      boolean prefixesAreOK)

Convert a long integer into roman numerals.

Parameters:

val - Value to convert.

prefixesAreOK - true_ to enable prefix notation (e.g. 4 = "IV"), false_ to disable prefix notation (e.g. 4 = "IIII").

Returns:

Roman numeral string.
