Method Detail

getLocale

public Locale getLocale()

getTwoDigitYearUpperBound

public int getTwoDigitYearUpperBound()

getMaxCount

public int getMaxCount()

Returns the maximum iteration count on circular evaluation.

Returns:

getMaxChange

public double getMaxChange()

Returns the maximum changes between two circular evaluation.

Returns:

getCurrent

public static final ZssContext getCurrent()

Returns the current Keikai Spreadsheet Context; never null. This is the Keikai Spreadsheet Context that every other objects shall use, unless they have special consideration.

Default: If setThreadLocal(org.apache.poi.ss.usermodel.ZssContext) was called with non-null, the value is returned. Otherwise, a default context is created and returned,

setThreadLocal

public static final ZssContext setThreadLocal(ZssContext ctx)

Sets the locale for the current thread only.

Each thread could have an independent ZssContext, called the thread locale.

When Invoking this method under a thread that serves requests, remember to clean up the setting upon completing each request.

ZssContext old = ZssContext.setThreadLocal(newValue);
try { 
  ...
} finally {
  ZssContext.setThreadLocal(old);
}

Parameters:

ctx - the thread ZssContext; null to denote no thread zssContext

Returns:

the previous thread locale

getThreadLocal

public static final ZssContext getThreadLocal()

Returns the Keikai Spreadsheet Contextdefined by setThreadLocal(org.apache.poi.ss.usermodel.ZssContext).
