Package com.singularsys.jep.misc

Class FunctionSet

java.lang.Object

com.singularsys.jep.misc.OneShotComponent

com.singularsys.jep.misc.FunctionSet

All Implemented Interfaces:

JepComponent, Serializable

Direct Known Subclasses:

ChainableFunctionSet, ChainedFunctionSet, LambdaFunctionSet, StreamFunctionSet, StringFunctionSet

public class FunctionSet
extends OneShotComponent

Holds a set of functions. These functions can be added to the main Jep function table by including the set in the Jep constructor. Jep jep = new Jep(new StringFunctionSet());, or by calling jep.setComponent(new StringFunctionSet());. Both add string functions to Jep

Since Jep 4.1 this class is a OneShotComponent and the functions are added once to the Jep instance. This prevents conflicts with manually adding functions.

Method Details

putIfSet

protected void putIfSet(String string,
 Supplier<PostfixMathCommandI> sup)

Only add the function if the string is not null and does not start with "!" This depends on syntax for missing resource in JepMessages where the key !property.name! is returned if the resource is missing.

Parameters:

string - the name of the function to add or string starting with "!" to omit the function

sup - supplier of the function to add, this is only called if the function is added

put

public void put(String string,
 PostfixMathCommandI pfmc)

firstInit

public void firstInit(Jep jep)
