Constructor Detail

DefaultPojoPathFunctionManager

public DefaultPojoPathFunctionManager()

The constructor.

DefaultPojoPathFunctionManager

public DefaultPojoPathFunctionManager(Map<String,PojoPathFunction> functionMap)

The constructor.

Parameters:

functionMap - is the underlying Map with the functions.

Method Detail

getFunction

public PojoPathFunction getFunction(String functionName)

This method gets a PojoPathFunction by its name. Therefore the PojoPathFunction instance has to be registered somehow in the implementation of this interface.

Specified by:

getFunction in interface PojoPathFunctionManager

Parameters:

functionName - is the name of the requested PojoPathFunction excluding the prefix.

Returns:

the requested PojoPathFunction or null if no PojoPathFunction is registered for the given functionName.

registerFunction

public PojoPathFunction registerFunction(PojoPathFunction function,
                                         String functionName)

This method registers the given function for the given functionName so it is available via getFunction(String).

Parameters:

function - is the PojoPathFunction to register.

functionName - is the associated name.

Returns:

the PojoPathFunction that was registered before for the given functionName and has now been replaced.
