Class dmd.expression.Expression
Methods
Name | Description |
---|---|
addDtorHook
|
Destructors are attached to VarDeclarations. Hence, if expression returns a temp that needs a destructor, make sure and create a VarDeclaration for that temp. |
addressOf
|
Take address of expression. |
checkModifiable
|
|
checkNogc
|
Calling function f. Check the @nogc-ness, i.e. if we're in a @nogc function we can only call other @nogc functions. Returns true if error occurs. |
checkPostblit
|
Check that the postblit is callable if t is an array of structs. Returns true if error happens. |
checkPurity
|
Calling function f. Check the purity, i.e. if we're in a pure function we can only call other pure functions. Returns true if error occurs. |
checkPurity
|
Accessing variable v. Check for purity and safety violations. Returns true if error occurs. |
checkReadModifyWrite
|
Check whether the expression allows RMW operations, error with rmw operator diagnostic if not. ex is the RHS expression, or NULL if ++/-- is used (for diagnostics) Returns true if error occurs. |
checkSafety
|
Calling function f. Check the safety, i.e. if we're in a @safe function we can only call @safe or @trusted functions. Returns true if error occurs. |
checkType
|
Check that the expression has a valid type. If not, generates an error "... has no type". |
checkValue
|
Check that the expression has a valid value. If not, generates an error "... has no value". |
combine
|
Combine e1 and e2 by CommaExp if both are not NULL. |
copy
|
Does *not* do a deep copy. |
deref
|
If this is a reference, dereference it. |
extractLast
|
If 'e' is a tree of commas, returns the leftmost expression by stripping off it from the tree. The remained part of the tree is returned via *pe0. Otherwise 'e' is directly returned and *pe0 is set to NULL. |
isBool
|
Does this expression statically evaluate to a boolean 'result' (true or false)? |
isLvalue
|
Return !=0 if expression is an lvalue. |
resolveLoc
|
Resolve _FILE__, _LINE__, _MODULE__, _FUNCTION__, _PRETTY_FUNCTION__, _FILE_FULL_PATH__ to loc. |
toBoolean
|
If expression can be tested for true or false, returns the modified expression. Otherwise returns ErrorExp. |
toLvalue
|
Give error if we're not an lvalue. If we can, convert expression to be an lvalue. |
factory
|
Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor. |
opCmp
|
Compare with another Object obj. |
opEquals
|
Test whether this is equal to o .
The default implementation only compares by identity (using the is operator).
Generally, overrides for opEquals should attempt to compare objects by their contents.
|
toHash
|
Compute hash function for Object. |
toString
|
Convert Object to a human readable string. |
