Static factory methods for various types of Expression s (in particular, BooleanOperation s and Predicate s).

  BooleanExpression search(StringPath stringPath, String searchPhrase, CaseSensitivity caseSensitivity)

  Predicate or(Predicate... predicates)
}

1	startsWith(T, Path) Creates BooleanOperation where the arguments use the operator 'startsWith'. Equivalent to SQL clause '.startsWith()'. This has a different outcome compared to the '.startsWith()'
2	eqOrNull(Path, T) Creates BooleanOperation where the arguments is checked for null. Equivalent with SQL clause '=' or 'IS NULL'.

Members

eqOrNull(Path, T)

Creates BooleanOperation where the arguments is checked for null. Equivalent with SQL clause '=' or 'IS NULL'.
