Method Detail

getEquationOperator

protected String getEquationOperator(DBDefinition db)

getIncludesNull

public boolean getIncludesNull()

Description copied from interface: ExpressionCanHaveNullValues

Returns TRUE if this expression requires support for possible NULL database values.

Support DBvolution at Patreon

Specified by:

getIncludesNull in interface ExpressionCanHaveNullValues

Overrides:

getIncludesNull in class AnyExpression<Boolean,BooleanResult,DBBoolean>

Returns:

TRUE if the expression should check for NULLs, FALSE otherwise.

copy

public StringExpression.StringIsLikeExpression copy()

Description copied from interface: DBExpression

A Complete Copy Of This DBValue.

Immutability in DBvolution is maintain by internally copying objects.

This method enables immutability by performing a deep copy of the object.

Singletons may return themselves but all other objects must return a new instance with copies of all mutable fields.

Specified by:

copy in interface BooleanResult

Specified by:

copy in interface DBExpression

Overrides:

copy in class BooleanExpression

Returns:

a copy of this DBValue
