Method Detail

getName

public String getName()

Used to parse the function string. This name is treated in a case-insensitive manner!

Specified by:

getName in interface Function

Specified by:

getName in class AbstractFunction

Returns:

the name by which you must call the function when used in an attribute equation.

getFunctionSummary

public String getFunctionSummary()

Used to provide help for users.

Specified by:

getFunctionSummary in interface Function

Specified by:

getFunctionSummary in class AbstractFunction

Returns:

a description of what this function does

getReturnType

public Class getReturnType()

Specified by:

getReturnType in interface Function

Specified by:

getReturnType in class AbstractFunction

Returns:

the static return type of this function, Object.class, Double.cLass, String.class, or Boolean.class. If the static return type is Object.class, the dynamic return type will be one of Double.cLass, String.class, or Boolean.class and will depend on the arguments passed to the function! Note, this is used by external tools used to filter a list of functions based on what a valid return type might be. In Cytoscape it is used in the attribute browser's formula builder.

evaluateFunction

public Object evaluateFunction(Object[] args)
                        throws IllegalArgumentException,
                               ArithmeticException

Description copied from class: AbstractFunction

Used to invoke this function.

Specified by:

evaluateFunction in interface Function

Specified by:

evaluateFunction in class AbstractFunction

Parameters:

args - the function arguments which must be either one or two objects of type Double

Returns:

the result of the function evaluation which is the maximum of the elements in the single list argument or the maximum of the one or more double arguments

Throws:

ArithmeticException

IllegalArgumentException - thrown if any of the arguments is not of type Double
