ROWID_INDEX

public static final int ROWID_INDEX

Got some bug with queries like SELECT rowid, * from blablablatable.
Returned with this queries column names array has duplicated id column instead of having
both rowid and id columns. It seems that there is some bug in generating cursor in current
Android version that I use for testing or common bug. Also it may be cause used PK are INTEGER NOT NUL PRIMARY KEY
that are aliased with ROWID. I don't care, instead of model.setRowID(cursor.getLong(cursor.getColumnIndex(ROWID)));
just would use model.setRowID(cursor.getLong(0));

Generates ContentValues instance from provided instance of KittyModel with usage of KittyTableConfiguration configuration. Also may throw some exceptions related with reflection access to field of provided model and KittyRuntimeException if there are some errors with KITTY_COLUMN implementation.

Parameters:

model - instance of KittyModel

table - table configuration

names - array of fields names or column names to include\exclude with usage of skipInclusionsExclusions(String[], int, KittyColumnConfiguration)

skipOrInclude - flag that determines what to do with provided KittyColumnConfiguration instance, may be IGNORE_INCLUSIONS_AND_EXCLUSIONS, INCLUDE_ALL_EXCEPT_SELECTED_COLUMN_NAMES, INCLUDE_ONLY_SELECTED_COLUMN_NAMES, INCLUDE_ALL_EXCEPT_SELECTED_FIELDS or INCLUDE_ONLY_SELECTED_FIELDS. If flag's value differs from any of inclusion predefined flags than would be used default flag (IGNORE_INCLUSIONS_AND_EXCLUSIONS)
