List of indexOfValue() Examples

Examples of indexOfValue()

weka.core.Attribute.indexOfValue()
Returns the index of a given attribute value. (The index of the first occurence of this value.) @param value the value for which the index is to be returned @return the index of the given attribute value if attributeis nominal or a string, -1 if it is not or the value can't be found
