Method Details

hasDefault

public final boolean hasDefault()

getDefaultConstant

public final E getDefaultConstant()

isInitial

public final boolean isInitial()

Returns true, if a value for the field should be specified on the creation of an item. This implementation returns ({@link #isFinal() isFinal()} || {@link #isMandatory() isMandatory()}) && !{@link #hasDefault()}.

Specified by:

isInitial in interface Settable<E>

Overrides:

isInitial in class Field<E>

addCopyFrom

protected final ItemField<?>[] addCopyFrom(ItemField<?> copyFrom)

toFinal

public abstract FunctionField<E> 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 Field<E>

See Also:

• Field.isFinal()

optional

public abstract FunctionField<E> 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 Field<E>

See Also:

• Field.isMandatory()

copy

public abstract FunctionField<E> copy()

copy

public final FunctionField<E> copy(CopyMapper mapper)

Specified by:

copy in interface Copyable

unique

public abstract FunctionField<E> unique()

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.

See Also:

• getImplicitUniqueConstraint()

nonUnique

public abstract FunctionField<E> nonUnique()

copyFrom

public abstract FunctionField<E> copyFrom(ItemField<?> copyFrom)

See Also:

• ItemField.copyTo(FunctionField)

noCopyFrom

public abstract FunctionField<E> noCopyFrom()

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

noDefault

public abstract FunctionField<E> noDefault()

defaultTo

public abstract FunctionField<E> defaultTo(E defaultConstant)

get

public final E get(@Nonnull
 Item item)

Specified by:

get in interface Function<E>

Specified by:

get in class Field<E>

get

public final E get(FieldValues item)

Specified by:

get in interface Function<E>

set

public final void set(@Nonnull
 Item item,
 E value)

Specified by:

set in class Field<E>

check

@Deprecated
public final void check(com.exedio.cope.TC tc,
 Join join)

Deprecated.

For internal use within COPE only.

Specified by:

check in interface Selectable<E>

append

@Deprecated
public final void append(com.exedio.cope.Statement bf,
 Join join)

Deprecated.

For internal use within COPE only.

Specified by:

append in interface Selectable<E>

appendSelect

@Deprecated
public void appendSelect(com.exedio.cope.Statement bf,
 Join join)

Deprecated.

For internal use within COPE only.

Specified by:

appendSelect in interface Selectable<E>

getImplicitUniqueConstraint

public UniqueConstraint getImplicitUniqueConstraint()

Returns the unique constraint of this field, that has been created implicitly when creating this field. Does return null, if there is no such unique constraint.

See Also:

• getUniqueConstraints()
• unique()

getUniqueConstraints

public List<UniqueConstraint> getUniqueConstraints()

Returns a list of unique constraints this field is part of. This includes an implicit unique constraint, if there is one for this field.

getImplicitCopyConstraint

@Deprecated
public CopyConstraint getImplicitCopyConstraint()

Deprecated.

Use getImplicitCopyConstraints() instead. Throws a RuntimeException, if getImplicitCopyConstraints() returns more than one constraint.

Returns the copy constraint of this field, that has been created implicitly when creating this field. Does return null, if there is no such copy constraint.

See Also:

• StringField.copyFrom(ItemField)
• ItemField.copyFrom(ItemField)

getImplicitCopyConstraints

@Deprecated
public List<CopyConstraint> getImplicitCopyConstraints()

Deprecated.

This method makes no sense anymore, since there is a ItemField.copyTo(FunctionField) as well.

Returns the copy constraints of this field, that has been created implicitly when creating this field. Does return an empty list, if there is no such copy constraint.

See Also:

• StringField.copyFrom(ItemField)
• ItemField.copyFrom(ItemField)

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<E>

Overrides:

getInitialExceptions in class Field<E>

isRedundantByCopyConstraint

public final boolean isRedundantByCopyConstraint()

searchUnique

public final Item searchUnique(E value)

Finds an item by it's unique fields.

Returns:

null if there is no matching item.

Throws:

NullPointerException - if value is null.

searchUnique

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

Finds an item by it's unique fields.

Returns:

null if there is no matching item.

Throws:

NullPointerException - if value is null.

searchUniqueStrict

@Nonnull
public final <P extends Item> P searchUniqueStrict(Class<P> typeClass,
 @Nonnull
 E value)
                                            throws IllegalArgumentException

Finds an item by its unique fields.

Throws:

NullPointerException - if value is null.

IllegalArgumentException - if there is no matching item.

copyFunctionField

@Deprecated
public final FunctionField<E> copyFunctionField()

Deprecated.

Renamed to copy().
