Method Detail

evaluate

public Value evaluate(Context c)

Evaluate in a general context

evaluateAsBoolean

public boolean evaluateAsBoolean(Context c)

Evaluate the function in a boolean context

getDataType

public int getDataType()

Determine the data type of the expression

Returns: Value.BOOLEAN

getDependencies

public int getDependencies()

Determine the dependencies

getName

public String getName()

Function name (for diagnostics)

reduce

public Expression reduce(int dep, Context c)
