CssCounterManager

public CssCounterManager()

Creates a new CssCounterManager instance.

Method Detail

clearManager

public void clearManager()

Clears information about counters. Target-counter(s) information remains.

pushEveryCounterToCounters

public void pushEveryCounterToCounters(com.itextpdf.styledxmlparser.node.IElementNode element)

Pushes every current non-null counter to stack of counters. This method should be called when we are about to process child nodes.

Parameters:

element - the element which counters shall be pushed

popEveryCounterFromCounters

public void popEveryCounterFromCounters(com.itextpdf.styledxmlparser.node.IElementNode element)

Pops every given counter from stack of counters. This method should be called when we have finished processing child nodes.

Parameters:

element - the element which counters shall be popped

resolveTargetCounter

public String resolveTargetCounter(String id,
                                   String counterName,
                                   CounterDigitsGlyphStyle listSymbolType)

Gets target-counter value for specified ID and counterName. Value is converted according to listSymbolType.

Parameters:

id - ID of the element. The first call adds ID to the Map, which means we require its value. The second call returns corresponding value if we already encountered corresponding element

counterName - name of the counter. The first call adds counterName to the Map, which means we require its value. The second call returns corresponding value if we already encountered corresponding element

listSymbolType - the list symbol type to convert counter's value. null if conversion is not required.

Returns:

target-counter value.

resolveTargetCounters

public String resolveTargetCounters(String id,
                                    String counterName,
                                    String counterSeparatorStr,
                                    CounterDigitsGlyphStyle listSymbolType)

Gets target-counter value for specified ID and counterName. Value is converted according to listSymbolType.

Parameters:

id - ID of the element. The first call adds ID at the Map, which means we require its value. The second call returns corresponding value if we already encountered this element

counterName - name of the counter. The first call adds name at the Map, which means we require its value. The second call returns corresponding value if we already encountered this element

counterSeparatorStr - separator to separate counters values.

listSymbolType - the list symbol type to convert counter's value. null if conversion is not required.

Returns:

target-counter value.

addTargetCounterIfRequired

public void addTargetCounterIfRequired(com.itextpdf.styledxmlparser.node.IElementNode node)

Adds counter value to every counter in the Map corresponding to a node ID.

Parameters:

node - node to take ID and scope from

addTargetCountersIfRequired

public void addTargetCountersIfRequired(com.itextpdf.styledxmlparser.node.IElementNode node)

Adds counters value to every counter in the Map corresponding to a node ID.

Parameters:

node - node to take ID and scope from

resolveCounter

                             CounterDigitsGlyphStyle listSymbolType)

Resolves a counter.

Parameters:
