shallowCopy
public FunctionTable shallowCopy()
Description copied from class:FunctionTable
Returns a new shallow copy of this function table. Calls theFunctionTable.threadSafeMapCopy()
method to ensure the table is safe to use a separate thread. All sub-classes should override this methods to create a function table of the matching type. A typical implementation would be@Override public FunctionTable shallowCopy() { Map<String,PostfixMathCommandI> newMap = this.threadSafeMapCopy(); return new myFunctionTable(newMap); }
using theFunctionTable.threadSafeMapCopy()
method to return a copy of the map of operators and a constructor taking this map which uses theFunctionTable(Map)
constructor.- Overrides:
shallowCopy
in classStandardFunctionTable
- Returns:
- a new shallow copy of this function table
