Class CaseInsensitiveFunctionTable

java.lang.Object
  com.singularsys.jep.FunctionTable
      com.singularsys.jep.misc.CaseInsensitiveFunctionTable

All Implemented Interfaces:

JepComponent, java.io.Serializable

public class CaseInsensitiveFunctionTable
extends FunctionTable

A version of a function table which is case insensitive.

Note that this table does not include any functions by default. You will need to add any functions you need.

 jep = new Jep();
 jep.setComponent(new CaseInsensitiveFunctionTable());
 jep.addFunction("if",new If());
 jep.parse("if(1>0,2,3)");
 System.out.println(jep.evaluate());
 

If you want to include all the functions in an existing table you can use

 FunctionTable oldFT = jep.getFunctionTable();
 jep.setComponent(new CaseInsensitiveFunctionTable());
 for(Entry ent:oldFT.entrySet()) {
     jep.addFunction(ent.getKey(), ent.getValue());
 }

getFunction

public PostfixMathCommandI getFunction(java.lang.String name)

Overrides:

getFunction in class FunctionTable

addFunction

public PostfixMathCommandI addFunction(java.lang.String name,
                                       PostfixMathCommandI pfmc)

Overrides:

addFunction in class FunctionTable

containsKey

public boolean containsKey(java.lang.String key)

Overrides:

containsKey in class FunctionTable

shallowCopy

public FunctionTable shallowCopy()

Description copied from class: FunctionTable

Returns a new shallow copy of this function table. The entries in the table refer to the the same instances of the postfix math commands. If sub-classes use pfmc's which are not thread safe they should override this methods and set a new instance for the table.

Overrides:

shallowCopy in class FunctionTable

Returns:

a new shallow copy of this function table
