hasSubjectData( name )

Tests if the current subject has any subject data with the given name.

Like loadSubjectData(), this function works very quickly because the subject data already cached in-memory, so this function does not need to “hit” the database.

Arguments

name	The name of the subject data to test for.

Returns

true if the subject has saved data with the given name, otherwise this function returns false.

Example

Loads an important piece of subject data from the database.

// Only load the subject data if the subject actually has the data

define somethingImportant = "missing"

if hasSubjectData("MyData") then

print("Loading subject data: MyData")

somethingImportant = loadSubjectData("Mydata")

else

print("MyData did not exist on the subject")

end if
