Method Detail

getObjectType

Class<?> getObjectType()

Gets the type of the object in the entry.

Returns:

The entry object type.

getCanonicalName

String getCanonicalName()

A RogLogQueryEngine.RogLogField's canonical name is computed as follows:

Entry field

For a field directly on the RogLog.Entry itself, the canonical field name is simply "entry."

Metadata Field

For a metadata field the, the canonical field name is simply "metadata."

Qualified Entity Fields

For a field on the RogLog.Entry's object the field name is calculated as /. where

• objectPackageName: the package name with '.' replaced with '/'
• EntityClassName: the result of Class.getCanonicalName() after the package name
• fieldPath: the field path

Unqualified Entity Fields

An unqualified entity field is represented as object.

Specified by:

getCanonicalName in interface IdxField<RogLog.Entry,T>

Returns:

The canonical name of the field.

registerPayloadType

void registerPayloadType(Class<?> type)

getPayloadTypes

Set<Class<?>> getPayloadTypes()
