Method Details

copy

public DoubleField copy()

Specified by:

copy in class FunctionField<Double>

toFinal

public DoubleField toFinal()

Description copied from class: Field

Returns a new Field, that differs from this Field by being final. If this Field is already final, the the result is equal to this Field.

Specified by:

toFinal in class FunctionField<Double>

See Also:

• Field.isFinal()

optional

public DoubleField optional()

Description copied from class: Field

Returns a new Field, that differs from this Field by being optional. If this Field is already optional, the the result is equal to this Field.

Specified by:

optional in class FunctionField<Double>

See Also:

• Field.isMandatory()

unique

public DoubleField unique()

Description copied from class: FunctionField

Returns a new FunctionField, that differs from this FunctionField by being unique. If this FunctionField is already unique, the the result is equal to this FunctionField.

Specified by:

unique in class FunctionField<Double>

See Also:

• FunctionField.getImplicitUniqueConstraint()

nonUnique

public DoubleField nonUnique()

Specified by:

nonUnique in class FunctionField<Double>

copyFrom

public DoubleField copyFrom(ItemField<?> copyFrom)

Specified by:

copyFrom in class FunctionField<Double>

See Also:

• ItemField.copyTo(FunctionField)

noCopyFrom

public DoubleField noCopyFrom()

Description copied from class: FunctionField

Returns a new FunctionField that differs from this FunctionField by having no copyFrom fields set.

Specified by:

noCopyFrom in class FunctionField<Double>

noDefault

public DoubleField noDefault()

Specified by:

noDefault in class FunctionField<Double>

defaultTo

public DoubleField defaultTo(Double defaultConstant)

Specified by:

defaultTo in class FunctionField<Double>

range

public DoubleField range(double minimum,
 double maximum)

min

public DoubleField min(double minimum)

max

public DoubleField max(double maximum)

getMinimum

public double getMinimum()

getMaximum

public double getMaximum()

getInitialExceptions

public Set<Class<? extends Throwable>> getInitialExceptions()

Description copied from interface: Settable

Returns the exceptions possibly thrown, when setting a value for this settable.

Specified by:

getInitialExceptions in interface Settable<Double>

Overrides:

getInitialExceptions in class FunctionField<Double>

getValueType

public com.exedio.cope.SelectType<Double> getValueType()

getMandatory

public double getMandatory(@Nonnull
 Item item)

Throws:

IllegalArgumentException - if this field is not mandatory.

set

public void set(@Nonnull
 Item item,
 double value)

searchUnique

@Nullable
public <P extends Item> P searchUnique(@Nonnull
 Class<P> typeClass,
 double value)

Finds an item by it's unique fields.

Returns:

null if there is no matching item.

See Also:

• FunctionField.searchUnique(Class, Object)

equal

public Condition equal(Double value)

Description copied from interface: Function

Returns a condition, that is true for all items, if and only if the value of this function for that item is equal to the given parameter.

notEqual

public Condition notEqual(Double value)
