Method Detail

getCounterValue

public int getCounterValue(String counterName)
Returns the value for the given counter. If no counter exists under that name, this method returns 0. This method always returns the current value and ignores all page-policy definitions. Enforcing the page policy is up to the page context.

Parameters: counterName

Returns: the value for the given counter.

getString

public String getString(String name)
Retrieves the value for a given string. The value returned always represents the *actual* value, ignoring any possibly defined page-policies.

Parameters: name

Returns:

incrementCounter

public void incrementCounter(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.

Parameters: name value

isCounterDefined

public boolean isCounterDefined(String counterName)
Checks, whether a counter is defined in this or one of the parent contexts. A counter gets defined by the 'counter-reset' property.

Parameters: counterName the counter name.

Returns: true, if the counter is defined, false otherwise.

resetCounter

public void resetCounter(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.

Parameters: name value

setString

public void setString(String name, String value, boolean define)
Sets a named string.

Parameters: name value define
