Constructor Detail

GradableObject

public GradableObject()

Method Detail

isCourseGrade

public abstract boolean isCourseGrade()

Returns:

Whether this gradable object is a course grade

isAssignment

public abstract boolean isAssignment()

Returns:

Whether this gradable object is an assignment

getIsCategory

public abstract boolean getIsCategory()

Returns:

Whether this gradable object is a category

getId

public Long getId()

Returns:

Returns the id.

setId

public void setId(Long id)

Parameters:

id - The id to set.

getGradebook

public Gradebook getGradebook()

Returns:

Returns the gradebook.

setGradebook

public void setGradebook(Gradebook gradebook)

Parameters:

gradebook - The gradebook to set.

getMean

public Double getMean()

Returns:

Returns the mean.

getFormattedMean

public Double getFormattedMean()

Returns:

Returns the mean while protecting against displaying NaN.

setMean

public void setMean(Double mean)

Parameters:

mean - The mean to set.

getName

public String getName()

This should really only be a field in Assignment objects, since the string describing CourseGrade needs to allow for localization. Unfortunately, such we keep CourseGrade and Assignment objects in the same table, and since we want Assignment names to be enforced as non-nullable, we're stuck with a bogus CourseGrade "name" field for now. The UI will have to be smart enough to disregard it.

Returns:

Returns the name.

setName

public void setName(String name)

Parameters:

name - The name to set.

getVersion

public int getVersion()

Returns:

Returns the version.

setVersion

public void setVersion(int version)

Parameters:

version - The version to set.

isRemoved

public boolean isRemoved()

Returns:

Returns the removed.

setRemoved

public void setRemoved(boolean removed)

Parameters:

removed - The removed to set.
