Class ResourceEntityHandlerImpl

java.lang.Object
  org.eclipse.emf.ecore.xmi.impl.URIHandlerImpl
      org.eclipse.emf.ecore.xmi.impl.ResourceEntityHandlerImpl

All Implemented Interfaces:

XMLResource.ResourceEntityHandler, XMLResource.URIHandler

public class ResourceEntityHandlerImpl
extends URIHandlerImpl
implements XMLResource.ResourceEntityHandler

This resource entity handler implementation extends the URI handler implementation so that this object can be used as both a resource entity handler and a URI handler since it's far more efficient to deresolve a URI once to compute the entity value than to deresolve it for each use and then map that deresolved result to an entity. For this reason, this implementation overrides deresolve(org.eclipse.emf.common.util.URI) to return the incoming URI.

Constructor Summary

ResourceEntityHandlerImpl(java.lang.String entityName)
Creates an instance that will generate entity names based on the given entity name followed by the count starting from 1 to ensure uniqueness.

Method Summary

URI	deresolve(URI uri) Returns the given URI.
protected URI	doDeresolve(URI uri) Returns the deresolved URI by calling super.
protected void	doSetBaseURI(URI uri) Sets the base URI by calling super.
protected java.lang.String	generateEntityName(java.lang.String entityValue) Generates a new unique entity name for the given entity value.
java.lang.String	getEntityName(java.lang.String entityValue) Returns the name associated with the entity value; a new name will be generated if there is not yet a name associated with the entity value.
java.util.Map<java.lang.String,java.lang.String>	getNameToValueMap() Returns the map of entity names to entity values to be recorded in the document during save.
void	handleEntity(java.lang.String entityName, java.lang.String entityValue) Records the entity name to entity value mapping.
void	reset() Resets the handler to its initial state.
void	setBaseURI(URI uri) Sets the base URI and if the URI has changed, resolves all the entity URIs values against the old base URI and then deresolves them against the new baseURI.

Method Detail

deresolve

public URI deresolve(URI uri)

Returns the given URI.

Specified by:

deresolve in interface XMLResource.URIHandler

Overrides:

deresolve in class URIHandlerImpl

uri - the URI to deresolve.

Returns:

the URI resolved against the base URI.

See Also:

URI.deresolve(URI)

doDeresolve

protected URI doDeresolve(URI uri)

Returns the deresolved URI by calling super.

Parameters:

uri - the URI to deresolve.

setBaseURI

public void setBaseURI(URI uri)

Sets the base URI and if the URI has changed, resolves all the entity URIs values against the old base URI and then deresolves them against the new baseURI.

Specified by:

setBaseURI in interface XMLResource.URIHandler

Overrides:

setBaseURI in class URIHandlerImpl

Parameters:

uri - the new base URI.

doSetBaseURI

protected void doSetBaseURI(URI uri)

Sets the base URI by calling super.

Parameters:

uri -

reset

public void reset()

Resets the handler to its initial state.

Specified by:

reset in interface XMLResource.ResourceEntityHandler

getEntityName

public java.lang.String getEntityName(java.lang.String entityValue)

Description copied from interface: XMLResource.ResourceEntityHandler

Returns the name associated with the entity value; a new name will be generated if there is not yet a name associated with the entity value.

Specified by:

getEntityName in interface XMLResource.ResourceEntityHandler

Parameters:

entityValue - the entity value for which a named entity is needed.

Returns:

the name associated with the entity value.

generateEntityName

protected java.lang.String generateEntityName(java.lang.String entityValue)

Generates a new unique entity name for the given entity value.

Parameters:

entityValue - the value for which an entity name is needed.

Returns:

a new unique entity name.

handleEntity

public void handleEntity(java.lang.String entityName,
                         java.lang.String entityValue)

Description copied from interface: XMLResource.ResourceEntityHandler

Specified by:

handleEntity in interface XMLResource.ResourceEntityHandler

Parameters:

entityName - the name of the entity.

entityValue - the associated value of the entity.

getNameToValueMap

public java.util.Map<java.lang.String,java.lang.String> getNameToValueMap()

Description copied from interface: XMLResource.ResourceEntityHandler

Returns the map of entity names to entity values to be recorded in the document during save.
