Member Function Documentation

at()

expression const& cudf::ast::tree::at ( size_t  index )

inline

get the expression at an index in the tree. Index is checked.

Parameters

index

index of expression in the ast tree

Returns

the expression at the specified index

Definition at line 634 of file expressions.hpp.

back()

expression const& cudf::ast::tree::back ( ) const

inline

get the last expression in the tree

Returns

the last inserted expression into the tree

Definition at line 621 of file expressions.hpp.

emplace()

template<typename Expr , typename... Args>

Expr const& cudf::ast::tree::emplace ( Args &&...  args )

inline

Add an expression to the AST tree.

Parameters

args	Arguments to use to construct the ast expression

Returns

a reference to the added expression

Definition at line 591 of file expressions.hpp.

front()

expression const& cudf::ast::tree::front ( ) const

inline

get the first expression in the tree

Returns

the first inserted expression into the tree

Definition at line 615 of file expressions.hpp.

operator=()

tree& cudf::ast::tree::operator= ( tree &&  )

default

move-assigns the AST tree

Returns

a reference to the move-assigned tree

operator[]()

expression const& cudf::ast::tree::operator[] ( size_t  index ) const

inline

get the expression at an index in the tree. Index is unchecked.

Parameters

index

index of expression in the ast tree

Returns

the expression at the specified index

Definition at line 641 of file expressions.hpp.

push()

template<typename Expr >

Expr const& cudf::ast::tree::push ( Expr  expr )

inline

Add an expression to the AST tree.

Parameters

expr	AST expression to be added

Returns

a reference to the added expression

Definition at line 606 of file expressions.hpp.

size()

size_t cudf::ast::tree::size ( ) const

inline

get the number of expressions added to the tree

Returns

the number of expressions added to the tree

Definition at line 627 of file expressions.hpp.
