ChainrEntry

public ChainrEntry(int index,
 Object chainrEntryObj,
 ClassLoader classLoader)

Process an element from the Chainr Spec into a ChainrEntry class. This method tries to validate the syntax of the Chainr spec, whereas the ChainrInstantiator deals with loading the Transform classes.

Parameters:

index - the index of the chainrEntryObj, used in reporting errors

chainrEntryObj - the unknown Object from the Chainr list

Method Details

getErrorMessageIndexSuffix

public String getErrorMessageIndexSuffix()

Generate an error message suffix what lists the index of the ChainrEntry in the overall ChainrSpec.

getSpec

public Object getSpec()

Returns:

Spec for the transform, can be null

getJoltTransformClass

public Class<? extends JoltTransform> getJoltTransformClass()

Returns:

Class instance specified by this ChainrEntry

isSpecDriven

public boolean isSpecDriven()

Returns:

true if the Jolt Transform specified by this ChainrEntry implements the SpecTransform interface
