Method Detail

getEntityDescriptorAccessor

public final EntityDescriptorAccessor getEntityDescriptorAccessor()

performImport

public Object performImport(File source)
                     throws IOException

imports entities from a xml-file. To allow arbitrary references between entities, import is performed in 2 stages:

1. create instances
2. setup properties of created instances

Specified by:

performImport in interface Importer

Parameters:

source - - the file that holds the xml data

Returns:

the imported object

Throws:

IOException - - raise exception from underlying layer to application

performImport

public Object performImport(String source)
                     throws IOException

imports entities from xml, that has been read into a string buffer. To allow arbitrary references between entities, import is performed in 2 stages:

1. create instances
2. setup properties of created instances

Specified by:

performImport in interface Importer

Parameters:

source - - the string buffer, that holds the xml data

Returns:

the imported object

Throws:

IOException - - raise exception from underlying layer to application

setEntityDescriptorAccessor

public final void setEntityDescriptorAccessor(EntityDescriptorAccessor i)

Description copied from interface: Importer

injection method: sets the description accessor to access EntityDescriptions

Specified by:

setEntityDescriptorAccessor in interface Importer

Parameters:

i - - the accessor to use
