Constructor Detail

BinaryExpr

public BinaryExpr(BinaryOperator operator,
                  Expression left,
                  Expression right,
                  SourceType type,
                  SourceLocation location)

Creates a binary expression and reparents both operands.

Parameters:

operator - the binary operator

left - the left operand

right - the right operand

type - the result type of the expression

location - the source location, or null for unknown

Throws:

NullPointerException - if operator, left, right, or type is null

BinaryExpr

public BinaryExpr(BinaryOperator operator,
                  Expression left,
                  Expression right,
                  SourceType type)

Creates a binary expression with an unknown source location.

Parameters:

operator - the binary operator

left - the left operand

right - the right operand

type - the result type of the expression

Throws:

NullPointerException - if operator, left, right, or type is null
