Method Detail

getField

<T> IdxField<RECORD,T> getField(String recordTypeName,
                              String fieldPath)

Gets a field from the given type name and fieldPath.

Parameters:

recordTypeName - The typeName of the log entry's object.

fieldPath - The bean path of the field.

Returns:

The resolved field.

getField

<T> IdxField<RECORD,T> getField(Class<?> recordType,
                              String fieldPath)

Gets a field for the given recordType and field path. Typically the recordType must be a subclass of the the IdxFieldResolver's RECORD type, but it is possible that some implementation can infer a field of RECORD type based on an alternative type.

Parameters:

recordType - The class of the corresponding record.

Parameters:

recordType - The class of the corresponding record.

fieldPath - The bean path of the field.

fieldType - Indicates the required type of the field.

pathTypes - For cases where types in the field path are ambiguous, this allows specifying specific types for the intermediate paths.
