TAN_ANGLE

public TAN_ANGLE()

Method Detail

executeOperator

public ValueBuffer executeOperator(java.util.LinkedList<ValueBuffer> args)

TAN returns the tangent of the given ANGLE value

Specified by:

executeOperator in interface OperatorImplementation

Parameters:

args - the argument list. The list must hold as many ValueBuffer objects as there are arguments to the operator, and each ValueBuffer object holds a value for some argument to the operator. ValueBuffer objects on the list must appear in the same order as the operator argument declarations.

Returns:

A ValueBuffer object holding the result value of the operator execution in internal format.

getArgumentTypeNames

public java.lang.String[] getArgumentTypeNames()

TAN takes a single argument of type ANGLE

Specified by:

getArgumentTypeNames in interface OperatorImplementation

Returns:

The names of the argument types

getReturnTypeName

public java.lang.String getReturnTypeName()

The return type is FLOAT

Specified by:

getReturnTypeName in interface OperatorImplementation

Returns:

the name of the type of the return value

isDeterministic

public boolean isDeterministic()

Description copied from interface: OperatorImplementation_V0104

Tells whether the operator is deterministic with respect to the arguments of its invocations. An operator is deterministic if and only if for any two distinct invocations, if all the argument values are the same, then the result value returned will also be the same. An example of a nondeterministic operators is RANDOM().

Specified by:

isDeterministic in interface OperatorImplementation_V0104

Returns:

true if the operator is deterministic.
