Method Detail
-
prettyPrintEMFType
public static java.lang.String prettyPrintEMFType(java.lang.Object typeObject)
Gives a human-readable name of an EMF type.
-
getFeature
public static org.eclipse.emf.ecore.EStructuralFeature getFeature(java.lang.Object o, java.lang.String featureName)
Get the structural feature with the given name of the given object.- Parameters:
o
- the object (must be an EObject)featureName
- the name of the feature- Returns:
- the EStructuralFeature of the object or null if it can not be found
-
getMessage
public static java.lang.String getMessage(IPatternMatch match, java.lang.String messageFormat)
Returns the message for the given match using the given format. The format string can refer to the value of parameter A of the match with $A$ and even access features of A (if it's an EObject), e.g. $A.id$. If the selected parameter does not exist, the string "[no such parameter]" is added If no feature is defined, but A has a feature called "name", then its value is used. If the selected feature does not exist, A.toString() is added. If the selected feature is null, the string "null" is added.- Parameters:
match
- cannot be null!messageFormat
- cannot be null!

getMessage
public static java.lang.String getMessage(IPatternMatch match, java.lang.String messageFormat, java.util.function.Function<java.lang.Object,java.lang.String> parameterValueTransformer)
Returns the message for the given match using the given format while transforming values with the given function. The format string can refer to the value of parameter A of the match with $A$ and even access features of A (if it's an EObject), e.g. $A.id$. The function will be called to compute the final string representation of the values selected by the message format. If the selected parameter does not exist, the string "[no such parameter]" is added If no feature is defined, but A has a feature called "name", then its value is passed to the function. If the selected feature does not exist, A is passed to the function. If the selected feature is null, the string "null" is added.- Parameters:
match
- cannot be null!messageFormat
- cannot be null!parameterValueTransformer
- cannot be null!- Since:
