Constructor Details

ASTExprOpBinary

public ASTExprOpBinary(int line,
 ASTExpression left,
 ASTExpression right,
 BinaryOpType operator)

Method Details

left

public ASTExpression left()

right

public ASTExpression right()

operator

public BinaryOpType operator()

setInferredType

public void setInferredType(LPCType inferredType)

Records the type selected by semantic analysis when an operator is ambiguous without context.

For example, mixed + mixed in an explicit string destination is treated as LPC string concatenation, while the same expression without that expected type remains numeric by default. JVMud uses this for narrow LPMud compatibility idioms such as legacy text efuns that return mixed, not as a general license to infer arbitrary operator meanings from context.

Parameters:

inferredType - resolved expression type, or null to fall back to structural inference

lpcType

public LPCType lpcType()
