Method Detail

getMetadata

EventTypeMetadata getMetadata()

Returns the type metadata.

Returns:

type metadata

getWriter

EventPropertyWriter getWriter(String propertyName)

Return a writer for writing a single property value.

Parameters:

propertyName - to write to

Returns:

null or writer if writable

getWriteableProperties

EventPropertyDescriptor[] getWriteableProperties()

Returns the writable properties.

Returns:

properties that can be written

getWritableProperty

Returns the descriptor for a writable property.

Parameters:

propertyName - to get descriptor for

Returns:

descriptor

getCopyMethod

EventBeanCopyMethod getCopyMethod(String[] properties)

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

getWriter
