Method Detail

lookupAttributeProperty

public static Object lookupAttributeProperty(Object value,
                                             String property)

lookupDeepNumericAttributeProperty

public static Double lookupDeepNumericAttributeProperty(Object value,
                                                        String propertyPath)

Reads a numeric value from a deep object graph as per ObjectUtil.lookupDeepAttributeProperty()

Parameters:

value - The object to look into

propertyPath - the property path to search

Returns:

the double value read from the object's property path or Double.NaN if it can't be read

lookupDeepAttributeProperty

public static Object lookupDeepAttributeProperty(Object value,
                                                 String propertyPath)

Looks up deep object graph attributes using a dot delimited java bean spec style path. So if I have an object A with a Member object B with a String value C I can refer to it as "b.c" and pass in the object A and I'll get back the value of a.getB().getC()

Parameters:

value - The object to look into

propertyPath - the property path to search

Returns:

the value read from the object's property path
