Constructor Detail

ListDataType

public ListDataType(String name)

Constructor for List field.

Method Detail

inheritRestrictions

protected void inheritRestrictions(BasicDataType origin)

Description copied from class: BasicDataType

If a datatype inherits from another datatype all its restrictions inherit too.

Overrides:

inheritRestrictions in class AbstractLengthDataType<List>

cloneRestrictions

protected void cloneRestrictions(BasicDataType origin)

Description copied from class: BasicDataType

If a datatype is cloned, the restrictions of it (normally implemented as inner classes), must be reinstantiated.

Overrides:

cloneRestrictions in class AbstractLengthDataType<List>

getLength

public long getLength(Object value)

Description copied from class: AbstractLengthDataType

In this method should be implemented how to calculate such a length for a certain value of this datatype. There does not exist a generic interface for this, so the implementation will cast to the expected type (String, byte[]..)

Specified by:

getLength in interface LengthDataType<List>

Specified by:

getLength in class AbstractLengthDataType<List>

getItemDataType

public DataType getItemDataType()

Returns the datatype of items in this list.

Returns:

the datatype as a DataType object, null if there are no restrictions

getItemDataTypeRestriction

public DataType.Restriction getItemDataTypeRestriction()

Returns the 'itemDataType' restriction, containing the value, errormessages, and fixed status of this attribute.

Returns:

the restriction as a DataType.Restriction

setItemDataType

public void setItemDataType(DataType value)

Sets the datatype of items in this list.

Parameters:

value - the datatype as a DataType object, null if there are no restrictions

getEnforceStrength

public int getEnforceStrength()

Description copied from interface: DataType

The maximum enforce strength of all restrictions on this datatype. See DataType.ENFORCE_ALWAYS, DataType.ENFORCE_ONCHANGE, DataType.ENFORCE_NEVER.

Specified by:

getEnforceStrength in interface DataType<List>

Overrides:

getEnforceStrength in class AbstractLengthDataType<List>

Returns:

maximum enforce strength

validateCastValue

protected Collection<LocalizedString> validateCastValue(Collection<LocalizedString> errors,
                                                        Object castValue,
                                                        Object value,
                                                        Node node,
                                                        Field field)

Overrides:

validateCastValue in class AbstractLengthDataType<List>

toStringBuilder

protected StringBuilder toStringBuilder()

Overrides:

toStringBuilder in class AbstractLengthDataType<List>
