data
- the data to check
-
doFindColumns
protected abstract int[] doFindColumns(weka.core.Instances data)
Returns the columns of interest in the dataset.- Parameters:
data
- the dataset to inspect- Returns:
- the columns of interest
-
findColumns
public int[] findColumns(weka.core.Instances data)
Returns the columns of interest in the dataset.- Specified by:
findColumns
in interfaceColumnFinder
- Parameters:
data
- the dataset to inspect- Returns:
- the columns of interest
-
compareTo
public int compareTo(Object o)
Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
Only compares the commandlines of the two objects.- Parameters:
o
- the object to be compared.- Returns:
- a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
-
equals
public boolean equals(Object o)
Returns whether the two objects are the same.
Only compares the commandlines of the two objects.
-
shallowCopy

shallowCopy
in interfaceadams.core.ShallowCopySupporter<ColumnFinder>
- Returns:
- the shallow copy
-
shallowCopy
public ColumnFinder shallowCopy(boolean expand)
Returns a shallow copy of itself, i.e., based on the commandline options.- Specified by:
shallowCopy
in interfaceadams.core.ShallowCopySupporter<ColumnFinder>
- Parameters:
expand
- whether to expand variables to their current values- Returns:
- the shallow copy
-
getColumnFinders
public static String[] getColumnFinders()
Returns a list with classnames of column finders.- Returns:
- the column finder classnames
-
forName
public static ColumnFinder forName(String classname, String[] options)
Instantiates the column finder with the given options.- Parameters:
classname
- the classname of the column finder to instantiateoptions
- the options for the column finder- Returns:
- the instantiated column finder or null if an error occurred
-
forCommandLine
public static ColumnFinder forCommandLine(String cmdline)
Instantiates the column finder from the given commandline (i.e., classname and optional options).- Parameters:
cmdline
- the classname (and optional options) of the column finder to instantiate- Returns:
- the instantiated column finder or null if an error occurred
