Method Details

op

protected long op(long result,
 long arg)

Specified by:

op in class BitwiseExp

getExpressionOperator

protected String getExpressionOperator(int index)

Description copied from class: Expression

Returns the operator printed between the operands, before the operand at the given index.

Specified by:

getExpressionOperator in class Expression

shallowCopy

public Expression shallowCopy()

Description copied from class: Expression

Creates a copy of this expression node, without copying children.

Specified by:

shallowCopy in class Expression

setOperands

public void setOperands(Object... operands)

Description copied from class: Expression

Replaces all the operands of this node with the given ones. Called by the constructor and by the parser once all the operands of a node are known, so a node that post-processes its operands overrides this method.

Overrides:
