Method Detail

postUpdateNestableTypes

protected void postUpdateNestableTypes()

Specified by:

postUpdateNestableTypes in class BaseNestableEventType

getUnderlyingType

public final Class getUnderlyingType()

Description copied from interface: EventType

Get the class that represents the Java type of the event type. Returns a Java bean event class if the schema represents a Java bean event type. Returns java.util.Map is the schema represents a collection of values in a Map.

Returns:

type of the event object

getCopyMethod

public EventBeanCopyMethod getCopyMethod(String[] properties)

Description copied from interface: EventTypeSPI

Returns the copy method, considering only the attached properties for a write operation onto the copy

Parameters:

properties - to write after copy

Returns:

copy method

getReader

public EventBeanReader getReader()

Description copied from interface: EventTypeSPI

Returns a reader for reading all properties of an event. This is completely optional and need only be implemented for performance.

Returns:

reader

getValue

public Object getValue(String propertyName,
                       Map values)

getWriter

public MapEventBeanPropertyWriter getWriter(String propertyName)

Description copied from interface: EventTypeSPI

Return a writer for writing a single property value.

Parameters:

propertyName - to write to

Returns:

null or writer if writable

getWritableProperty

public EventPropertyDescriptor getWritableProperty(String propertyName)

Description copied from interface: EventTypeSPI

Returns the descriptor for a writable property.

Parameters:

propertyName - to get descriptor for

Returns:

descriptor

getWriteableProperties

public EventPropertyDescriptor[] getWriteableProperties()

Description copied from interface: EventTypeSPI

Returns the writable properties.

Returns:

properties that can be written

getWriter

public EventBeanWriter getWriter(String[] properties)

Description copied from interface: EventTypeSPI

Returns the write for writing a set of properties.

Parameters:

properties - to write

Returns:

writer
