Interface EPath

public interface EPath

An EPath represents a resolver which converts String-based expressions into Objects. Those Objects were provided by the underlying data model and represent their properties.

For every modeled entity package within the application model, the generation will result in a Java package containing the modeled entities as Java classes and one global EPath implementation per package. This implementation will be internally used to convert expressions, e.g. to parse JSON into entities or to get the expression value for ContentAdapters.

Method Summary

Modifier and Type	Method and Description
java.lang.Object	getObjectForExpression(java.lang.Object root, ExpressionFragment fragment) Returns a Object for the passed expression or null, if the expression could not be found.
void	setObjectForExpression(java.lang.Object root, ExpressionFragment fragment, java.lang.Object value) Sets a Object for the passed expressions.

Method Detail

getObjectForExpression

java.lang.Object getObjectForExpression(java.lang.Object root,
                                        ExpressionFragment fragment)

Returns a Object for the passed expression or null, if the expression could not be found. This basically means that there is no property matches the passed ExpressionFragment.getFragment() name.

The passed root must be a generated entity class which is modeled with EML.

Parameters:

root -

fragment -

Returns:

setObjectForExpression

void setObjectForExpression(java.lang.Object root,
                            ExpressionFragment fragment,
                            java.lang.Object value)

Sets a Object for the passed expressions. If the expression is not corresponding to a entities property, nothing happens.

The passed root must be a generated entity class which is modeled with EML.

Parameters:

root -

fragment -

value -
