Constructor Detail

NaryOperatorExpn

public NaryOperatorExpn(Expn[] operands)

Construct a new n'ary operator with the given operands.

Parameters:

operands - an arrya of operands

Method Detail

setOperand

public void setOperand(int i,
                       Expn operand)

Description copied from class: OperatorExpn

Sets the i'th operand (0-based) to the given expression. If the expression is null, cleanly removes the previous i'th operand.

Overrides:

setOperand in class OperatorExpn

Parameters:

i - the index (0-based) of the operand to set

setOperand

public void setOperand(Expn[] operands)

Description copied from class: OperatorExpn

Sets all the operands at once Either this method or setNumOperands must be called before any other

Overrides:

setOperand in class OperatorExpn
