Method Details

contributesTo

public abstract boolean contributesTo(Object target)

findContributedMethodForUnevaluatedParameters

public ObjectMethod findContributedMethodForUnevaluatedParameters(Object target,
 String name,
 List<Expression> parameterExpressions,
 IEolContext context)

findContributedMethodForEvaluatedParameters

public ObjectMethod findContributedMethodForEvaluatedParameters(Object target,
 String name,
 Object[] parameters,
 IEolContext context)

findContributedMethodForEvaluatedParameters

public ObjectMethod findContributedMethodForEvaluatedParameters(Object target,
 String name,
 Object[] parameters,
 IEolContext context,
 boolean overrideContextOperationContributorRegistry)

includeInheritedMethods

protected boolean includeInheritedMethods()

Specifies whether methods in the supertype of the contributor should be included when finding contributed operations. Typically, this should not be the case and, as such, this method returns false by default.

getReflectionTarget

protected Object getReflectionTarget(Object target)

getTarget

protected Object getTarget()

Returns:

The target field.

setContext

public void setContext(IEolContext context)

getContext

protected IEolContext getContext()

Returns:

Since:
