checkArguments

protected void checkArguments(ELMatrix[] argument)

apply

public void apply(ELMatrix[] argument,
                  ELMatrix out,
                  ELEnvironment environment)

Description copied from interface: ELOperator

Applies this operator.

apply in interface ELOperator

combine

protected abstract float combine(float a,
                                 float b)

Override this to provide your element-by-element operator.

clamp

protected void clamp(ELMatrix out)

combine

protected void combine(ELMatrix out,
                       ELMatrix other)

Combines the cumulative result (out) with the next argument (other).

getMaxNumArguments

public int getMaxNumArguments()

Description copied from interface: ELOperator

Returns the maxiumum number of arguments this operator accepts. Note: All operators that accept an argument accept an ELMatrix argument.

Specified by:

getMinNumArguments

public int getMinNumArguments()

Description copied from interface: ELOperator

Returns the minimum number of arguments this operator accepts.

Specified by:

getMinNumArguments in interface ELOperator

unparse

public java.lang.String unparse()

Description copied from interface: ELOperator

How this operator should appear in EL code.

Specified by:

unparse in interface ELOperator
