Constructor Detail

CastExpr

public CastExpr(SourceType targetType,
                Expression expression,
                SourceLocation location)

Creates a cast of the given expression to the target type and reparents the operand.

Parameters:

targetType - the type cast to

expression - the expression being cast

location - the source location, or null for unknown

Throws:

NullPointerException - if targetType or expression is null

CastExpr

public CastExpr(SourceType targetType,
