Constructor Summary

BinaryDataType(String name)
Constructor for binary field.

Method Summary

long	getLength(Object value) 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[]..)
Pattern	getValidMimeTypes() Returns a regular expression which describes wich mime-types are valid for blobs with this DataType.
protected void	inheritProperties(BasicDataType origin) Properties are members of the datatype that can easily be copied/clones.
void	setValidMimeTypes(Pattern pattern)

Constructor Detail

BinaryDataType

public BinaryDataType(String name)

Constructor for binary field.

Parameters:

name - the name of the data type

Method Detail

inheritProperties

protected void inheritProperties(BasicDataType origin)

Description copied from class: BasicDataType

Properties are members of the datatype that can easily be copied/clones.

Overrides:

inheritProperties in class BasicDataType

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

Specified by:

getLength in class AbstractLengthDataType

getValidMimeTypes

public Pattern getValidMimeTypes()

Returns a regular expression which describes wich mime-types are valid for blobs with this DataType. This is not yet available as a Restriction, only as a property.

setValidMimeTypes

public void setValidMimeTypes(Pattern pattern)
