Detailed Description

Primitive types should only be declared once inside the codebase to avoid conflicts A node in an expression. Can be constructed from any C++ type that has a corresponding DEFINE_EXPRESSION_NODE_TYPE. Evaluation behaviour (unary/binary operator etc) is defined in the expression grammar, rather than the type itself.

Member Function Documentation

Cast()

template<typename T >

const T * FExpressionNode::Cast

(

)

const

Cast this node to the specified type. Will return nullptr if the types do not match.

)

const

Copy this node and its wrapped data

GetData() [1/2]

Impl::IExpressionNodeStorage * FExpressionNode::GetData ( )

private

Helper accessor to the data interface. Returns null for empty containers.

MaxStackAllocationSize

constexpr uint32 FExpressionNode::MaxStackAllocationSize = 64 - sizeof(FGuid)

staticconstexprprivate

The maximum size of type we will allow allocation on the stack (for efficiency). Anything larger will be allocated on the heap.
