Specified by:

getCounterValue in interface ElementContext

Parameters:

the value for the given counter.

incrementCounter

public void incrementCounter(java.lang.String name,
                             int value)

Increments the counter with the given name. If no counter is known under that name, the root node will create one.

Specified by:

incrementCounter in interface ElementContext

Parameters:

name -

value -

resetCounter

public void resetCounter(java.lang.String name,
                         int value)

Reseting an counter creates a new Counter-Instance. Counters from parent elements are not affected and remain unchanged. All further operations issued by all sub-elements will now work with this counter.

Specified by:

resetCounter in interface ElementContext

Parameters:

name -

value -

isCounterDefined

public boolean isCounterDefined(java.lang.String counterName)

Description copied from interface: ElementContext

Checks, whether a counter is defined in this or one of the parent contexts. A counter gets defined by the 'counter-reset' property.

Specified by:

isCounterDefined in interface ElementContext

Parameters:

counterName - the counter name.

Returns:

true, if the counter is defined, false otherwise.

setString

public void setString(java.lang.String name,
                      java.lang.String value,

Parameters:

name - the name

value - the value

define - if set to true, this defines a new nesting context.

getString

public java.lang.String getString(java.lang.String name)
