List of numValues() Examples

Examples of numValues()

com.bloomberglp.blpapi.Element.numValues()
weka.core.Attribute.numValues()
Returns the number of attribute values. Returns 0 for attributes that are not either nominal, string, or relation-valued. @return the number of attribute values
weka.core.Instance.numValues()
Returns the number of values present. Always the same as numAttributes(). @return the number of values
