Method Detail

getObject

public Object getObject(Object root,
                        String propName)
                 throws Exception

Throws:

Exception

getPropVal

public Object getPropVal(Object root,
                         String propName)

Retrieves the raw prop value from root object.

The similar getProperty(Object, String) method (also in this class )should be revisited and possibly eliminated. That version attempts to retrieve indexed prop vals from lists/arrays, but doesn't provide a way to retrieve the list or array objects themselves.

getProperty

public Object getProperty(Object root,
                          String propName)
                   throws Exception

Throws:

Exception

hasProperty

public boolean hasProperty(Object root,
                           String propName)

setProperty

public void setProperty(Object root,
                        String propName,
                        List<RowMetaAndData> data,
                        String dataN)
                 throws HopException

Throws:

HopException

runPostInjectionProcessing

public void runPostInjectionProcessing(Object object)
