All Superinterfaces:

java.lang.Cloneable

public interface DataType<L>
extends java.lang.Cloneable

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

setPhysical

void setPhysical(java.lang.Class cls)

Set the java type for the data

Parameters:

cls -

getPhysical

java.lang.Class getPhysical()

Returns the physical type used by the runtime.

Returns:

the physical type used by the runtime

getLogical

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 Class identifies a Java type by name and ClassLoader; this includes Java Classes as they are specializations of Type
• a XMLType identifies an XML type by local name and namespace

Returns:

the logical type name

getDataBinding

java.lang.String getDataBinding()

Returns:

setDataBinding

void setDataBinding(java.lang.String dataBinding)

Parameters:

dataBinding - the dataBinding to set

clone

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

Returns:

Throws:

java.lang.CloneNotSupportedException

setLogical

void setLogical(L logical)

Parameters:

logical - the logical to set
