Method Detail

isInCollection

public BooleanExpression isInCollection(Collection<UUIDResult> values)

Specified by:

isInCollection in class InExpression<UUID,UUIDResult,DBUUID>

isNotInCollection

public BooleanExpression isNotInCollection(Collection<UUIDResult> values)

Specified by:

isNotInCollection in class InExpression<UUID,UUIDResult,DBUUID>

expression

public UUIDResult expression(UUID value)

Specified by:

expression in class AnyExpression<UUID,UUIDResult,DBUUID>

expression

public UUIDResult expression(UUIDResult value)

Specified by:

expression in class AnyExpression<UUID,UUIDResult,DBUUID>

expression

public UUIDResult expression(DBUUID value)

asExpressionColumn

public DBUUID asExpressionColumn()

Description copied from interface: ExpressionColumn

Creates a QueryableDatatype version of the expression suitable for use as a column.

For example: @DBColumn public DBString title = person.column(person.fullname).substringBefore(" ").asExpressionColumn();

Support DBvolution at Patreon

Specified by:

asExpressionColumn in interface ExpressionColumn<DBUUID>

Returns:

a QDT version of the expression

getQueryableDatatypeForExpressionValue

public QueryableDatatype<?> getQueryableDatatypeForExpressionValue()

Description copied from interface: DBExpression

Provides a blank instance of the QueryableDatatype used by this expression.

You are probably looking for ExpressionColumn.asExpressionColumn().

Note that this method is not good for use in everyday DBvolution code and should probably be reserved for meta-programming.

Specified by:

getQueryableDatatypeForExpressionValue in interface DBExpression

Returns:

the QueryableDatatype subclass that corresponds to the results of this expression

copy

public UUIDExpression 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 DBExpression

Specified by:

copy in interface UUIDResult

Returns:

a copy of this DBValue

is

public BooleanExpression is(UUIDResult anotherInstance)

Description copied from interface: EqualComparable

Creates a BooleanExpression that compares the 2 values using the EQUALS operation.

Specified by:

is in interface EqualComparable<UUID,UUIDResult>

Parameters:

anotherInstance - an instance to compare to

Support DBvolution at Patreon

Returns:

a BooleanExpression

isNot

public BooleanExpression isNot(UUIDResult anotherInstance)

Description copied from interface: EqualComparable

Creates a BooleanExpression that compares the 2 values using the NOT EQUALS operation.

Specified by:

isNot in interface EqualComparable<UUID,UUIDResult>

Parameters:

anotherInstance - and instance to compare to

Support DBvolution at Patreon

Returns:

a BooleanExpression

is

public BooleanExpression is(UUID anotherInstance)

Description copied from interface: EqualComparable

Creates a BooleanExpression that compares the 2 values using the EQUALS operation.

Specified by:

is in interface EqualComparable<UUID,UUIDResult>

Parameters:

anotherInstance - an instance to compare to

Support DBvolution at Patreon

Returns:

a BooleanExpression

isNot

public BooleanExpression isNot(UUID anotherInstance)

Description copied from interface: EqualComparable

Creates a BooleanExpression that compares the 2 values using the NOT EQUALS operation.

Specified by:

isNot in interface EqualComparable<UUID,UUIDResult>

Parameters:

anotherInstance - and instance to compare to

Support DBvolution at Patreon

Returns:

a BooleanExpression

stringResult

public StringExpression stringResult()

Description copied from interface: ExpressionHasStandardStringResult

Converts the expression into the standard string/character expression representing the value.

Not all types have a standard string/character representation, notably dates.

Please note that this is not the SQL version of the expression (toSQLString() will provide that), nor does this provide a String of the value.

To get the string value use the stringValue method of the appropriate QDT.

Support DBvolution at Patreon

Specified by:

stringResult in interface ExpressionHasStandardStringResult

Returns:

a StringExpression of the expression.
