public interface SourceExpression
extends SourceElement, CompiledExpression

The SourceExpression is essentially the union of all the various operators and primaries. 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

getConstantValue

java.lang.Object getConstantValue()

Determine if this expression is a constant expression, and if so, compute the constant value of this expression

Returns:

An Object representing the constant value of this expression or null if this expression is not a constant expression

getExpressionCode

int getExpressionCode()

Returns:

One of the OPT_* constants exactly identifying what kind of expression this is. Valid values are found in JavaOperators.

getOperatorCode

int getOperatorCode()

Same thing as getExpressionCode(). Provided in case that's the first appropriate method a client would have expected.

getFirstOperand

SourceExpression getFirstOperand()

Returns:

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

getSecondOperand

SourceExpression getSecondOperand()

Returns:

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

getThirdOperand

SourceExpression getThirdOperand()

Returns:

the SourceExpression 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 SourceExpressions. Always non-null. May be zero-length. Returns a collection of SourceExpressions.

getOperandCount

int getOperandCount()

Returns:

The size of the operand array.

getOperandAt

SourceExpression 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.
