Determine among the Map-type properties which properties are Bean-type event type names, rewrites these as Class-type instead so that they are configured as native property and do not require wrapping, but may require unwrapping.

Parameters:

typing - properties of map type

eventAdapterService - event adapter service

Returns:

compiled properties, same as original unless Bean-type event type names were specified.

isPropertyArray

public static boolean isPropertyArray(java.lang.String name)

Returns true if the name indicates that the type is an array type.

Parameters:

name - the property name

Returns:

true if array type

getPropertyRemoveArray

public static java.lang.String getPropertyRemoveArray(java.lang.String name)

Returns the property name without the array type extension, if present.

Parameters:

name - property name

Returns:

property name with removed array extension name
