public interface ExpressionT
extends Tree

Common supertypes for all expressions. If it is a primary, selector, or method invocation, it has a name. Otherwise, it is an operator of some sort and has operands. With each enumerated constant is a description of which fields are non-null and useful.

Method Detail

getExpressionKind

ExpressionT.ExpressionKind getExpressionKind()

Identifies the operation this expression is performing.

getFirstOperand

ExpressionT getFirstOperand()

Returns:

the ExpressionT representing the first operand. Non-null if this expression is an operator (and hence has operands).

getSecondOperand

ExpressionT getSecondOperand()

Returns:

the ExpressionT representing the second operand. Non-null if this operator has a second operand.

getThirdOperand

ExpressionT getThirdOperand()

Returns:

the ExpressionT representing the third operand. Non-null if this has a third operand, e.g. "x? x: x".

getOperands

java.util.List getOperands()

Returns:

the array of ExpressionTs. Always non-null. May be zero-length. Returns a collection of ExpressionTs.

List of ExpressionTs.

getOperandCount

int getOperandCount()

Returns:

The size of the operand array.

getOperandAt

ExpressionT getOperandAt(int index)

Gets the operand at the specified index in the operand array.

Parameters:

index - 0-based.

Returns:

Null if the indicated operand doesn't exist.
