Constructor Detail

NodeCounter

protected NodeCounter(Translet translet,
                      DOM document,
                      DTMAxisIterator iterator)

Method Detail

setStartNode

public abstract NodeCounter setStartNode(int node)

Set the start node for this counter. The same NodeCounter object can be used multiple times by resetting the starting node.

setValue

public NodeCounter setValue(double value)

If the user specified a value attribute, use this instead of counting nodes.

setFormatting

protected void setFormatting(java.lang.String format,
                             java.lang.String lang,
                             java.lang.String letterValue,
                             java.lang.String groupSep,
                             java.lang.String groupSize)

Sets formatting fields before calling formatNumbers().

setTokens

private final void setTokens(java.lang.String format)

setDefaultFormatting

public NodeCounter setDefaultFormatting()

Sets formatting fields to their default values.

getCounter

public abstract java.lang.String getCounter()

Returns the position of node according to the level and the from and count patterns.

getCounter

public java.lang.String getCounter(java.lang.String format,
                                   java.lang.String lang,
                                   java.lang.String letterValue,
                                   java.lang.String groupSep,
                                   java.lang.String groupSize)

Returns the position of node according to the level and the from and count patterns. This position is converted into a string based on the arguments passed.

matchesCount

public boolean matchesCount(int node)

Returns true if node matches the count pattern. By default a node matches the count patterns if it is of the same type as the starting node.

matchesFrom

public boolean matchesFrom(int node)

Returns true if node matches the from pattern. By default, no node matches the from pattern.

formatNumbers

protected java.lang.String formatNumbers(int value)

Format a single value according to the format parameters.

formatNumbers

protected java.lang.String formatNumbers(int[] values)

Format a sequence of values according to the format paramaters set by calling setFormatting().

formatValue

private void formatValue(int value,
                         java.lang.String format,
                         java.lang.StringBuffer buffer)

Format a single value based on the appropriate formatting token. This method is based on saxon (Michael Kay) and only implements lang="en".

alphaValue

private java.lang.String alphaValue(int value,
                                    int min,
                                    int max)

romanValue

private java.lang.String romanValue(int n)
