Constructor Detail

GSVModel

public GSVModel(String path)
         throws IllegalArgumentException

Creates a new GSVModel using the path to an '.eomodeld' file.

Example of creating a GSVModel for the Movies example which ships with WebObjects.

EOModel eoModel = EOModelGroup.defaultGroup().modelNamed("Moview");
GSVModel model = new GSVModel(eoModel.path());


Parameters:

path - Path to an '.eomodeld' file.

Throws:

IllegalArgumentException - Thrown if valid '.eomodeld' file does not exist at the specified path.

GSVModel

public GSVModel(WOXMLDecoder decoder)

WOXMLCoding Impl

Parameters:

decoder - WOXMLDecoder

See Also:

encodeWithWOXMLCoder(com.webobjects.appserver.xml.WOXMLCoder)

Method Detail

validateEOModelForPath

public boolean validateEOModelForPath(String path)

Determines that there is indeed a file located at the given path.

Parameters:

path - Path to the desired '.eomodeld' file.

Returns:

true if an '.eomodeld' file is located at the given path; otherwise, we return false.

saveModel

public boolean saveModel()

Saves the GSVModel to inside the '.eomodeld' file wrapper.

Returns:

true if save is successful; otherwise, returns false.

eomodelGroup

public EOModelGroup eomodelGroup()

Returns the EOModelGroup that is being used to query information from the EOModel.

Returns:

EOModelGroup for the EOModel.

eomodelName

public String eomodelName()

Returns the EOModel Name for the associated GSVModel.

Returns:

Name of the EOModel

eomodelPath

public String eomodelPath()

Returns the path of the '.eomodeld' file.

Returns:

Path of the EOModel File.

See Also:

setEomodelPath(java.lang.String)

setEomodelPath

public void setEomodelPath(String path)

Set the path of the EOModel file.

Parameters:

path - Path of the EOModel File.

eomodelPath()

entities

public NSArray entities()

Returns the NSArray of GSVEntity Objects.

Returns:

NSArray of GSVEntity Objects.

addEntity

public void addEntity(GSVEntity newEntity)
               throws IllegalArgumentException

Adds a GSVEntity object to this GSVModel. The GSVEntity must not already exsit.
If it does, IllegalArgumentException is thrown.

Parameters:

newEntity - GSVEntity object

Throws:

IllegalArgumentException - GSVEnitity already exsits.

entityNamed

public GSVEntity entityNamed(String name)

Returns the GSVEntity object for the provided entity name.

Parameters:

name - name of entity

Returns:

GSVEntity if an GSVEntity is named name, null if it could not be found.
