  org.apache.tuscany.sca.interfacedef.impl.DataTypeImpl<L>

All Implemented Interfaces:

java.lang.Cloneable, DataType<L>

public class DataTypeImpl<L>
extends java.lang.Object
implements DataType<L>

Representation of the type of data associated with an operation. Data is represented in two forms: the physical form used by the runtime and a logical form used by the assembly. The physical form is a Java Type because the runtime is written in Java. This may be the same form used by the application but it may not; for example, an application that is performing stream processing may want a physical form such as an InputStream to semantially operate on application data such as a purchase order. The logical description is that used by the assembly model and is an identifier into some well-known type space; examples may be a Java type represented by its Class or an XML type represented by its QName. Every data type may also contain metadata describing the expected data; for example, it could specify a preferred data binding technology or the size of a typical instance.

Method Detail

getPhysical

public java.lang.Class<?> getPhysical()

Returns the physical type used by the runtime.

Specified by:

getPhysical in interface DataType<L>

Returns:

the physical type used by the runtime

setPhysical

public void setPhysical(java.lang.Class<?> physical)

Description copied from interface: DataType

Set the java type for the data

Specified by:

setPhysical in interface DataType<L>

Parameters:

physical - the physical to set

getGenericType

public java.lang.reflect.Type getGenericType()

Get the java generic type

Specified by:

getGenericType in interface DataType<L>

Returns:

The java generic type

setGenericType

public void setGenericType(java.lang.reflect.Type genericType)

Set the java generic type

Specified by:

setGenericType in interface DataType<L>

Parameters:

genericType -

getLogical

public L getLogical()

Returns the logical identifier used by the assembly. The type of this value identifies the logical type system in use. Known values are:

• a java.lang.reflect.Type identifies a Java type by name and ClassLoader; this includes Java Classes as they are specializations of Type
• a javax.xml.namespace.QName identifies an XML type by local name and namespace

Specified by:

getLogical in interface DataType<L>

Returns:

the logical type name

setLogical

public void setLogical(L logical)

Description copied from interface: DataType

Set the logical type of the data type

Specified by:

setLogical in interface DataType<L>

Parameters:

logical - the logical to set

getDataBinding

public java.lang.String getDataBinding()

Description copied from interface: DataType

Get the databinding for the given data type

Specified by:

getDataBinding in interface DataType<L>

Returns:

the databinding

setDataBinding

public void setDataBinding(java.lang.String dataBinding)

Description copied from interface: DataType

Set the databinding for the given data type

Specified by:

setDataBinding in interface DataType<L>

Parameters:

dataBinding - the dataBinding to set

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Description copied from interface: DataType
