ColorField

public ColorField()

Method Details

copy

public ColorField copy(CopyMapper mapper)

Specified by:

copy in interface Copyable

toFinal

public ColorField toFinal()

optional

public ColorField optional()

defaultTo

public ColorField defaultTo(Color defaultConstant)

allowAlpha

public ColorField allowAlpha()

See Also:

• isAlphaAllowed()

isInitial

public boolean isInitial()

Description copied from interface: Settable

Returns true, if a value for the settable should be specified on the creation of an item.

Specified by:

isInitial in interface Settable<Color>

isFinal

public boolean isFinal()

Description copied from interface: Settable

Returns true, if a value for the settable can be specified on the creation of an item only, thus cannot be modified later.

Specified by:

isFinal in interface Settable<Color>

isMandatory

public boolean isMandatory()

Specified by:

isMandatory in interface Settable<Color>

getInitialType

public Class<?> getInitialType()

Specified by:

getInitialType in interface Settable<Color>

isAlphaAllowed

public boolean isAlphaAllowed()

If this method returns false, this ColorField allows opaque colors only. This means, the alpha value must be 255. If this method returns true, this ColorField allows any colors with any alpha value.

getDefaultConstant

public Color getDefaultConstant()

getRGB

public IntegerField getRGB()

Returns the field containing almost the result of Color.getRGB() of the persisted color. The difference is as follows:

For Color.getRGB() an alpha value of 255 means that the color is completely opaque and an alpha value of 0 means that the color is completely transparent.

Values of the IntegerField returned by this method do have the reverse meaning: An alpha value of 255 means that the color is completely transparent and an alpha value of 0 means that the color is completely opaque.

This transformation ensures, that the persistent value of any opaque Color does not depend on whether the ColorField allows alpha or not.

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<Color>

get

public Color get(@Nonnull
 Item item)

set

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

execute

public SetValue<?>[] execute(Color value,
 Item exceptionItem)

Specified by:

execute in interface Settable<Color>

toRGB

public static int toRGB(Color color)

Returns the value for field getRGB() representing the given color.

fromRGB

public static Color fromRGB(int rgb)

Converts a value for field getRGB() into a color.

bind

public ColorFunction bind(Join join)

isNull

public IsNullCondition<?> isNull()

Specified by:

isNull in interface ColorFunction

isNotNull

public IsNullCondition<?> isNotNull()

Specified by:

isNotNull in interface ColorFunction

equal

public Condition equal(Color value)

Specified by:

equal in interface ColorFunction

notEqual

public Condition notEqual(Color value)

NOT EQUAL Condition. Note: according to SQL, a NULL value is evaluated to unknown, so a NOT EQUAL using a non null RHS is false for null values

Specified by:

notEqual in interface ColorFunction

isOpaque

public Condition isOpaque()

isNotOpaque

public Condition isNotOpaque()
