@Deprecated
public DoubleLiteral fullCopy()

Deprecated. Please use treeCopy or treeCopyNoTransform instead

Create a deep copy of the AST subtree at this node. The copy is dangling, i.e. has no parent.

Overrides:fullCopy in class NumericLiteral

Returns:: dangling copy of the subtree at this node
Source: Declared in /home/jesper/git/extendj/ASTNode at line 80

public DoubleLiteral treeCopyNoTransform()

Create a deep copy of the AST subtree at this node. The copy is dangling, i.e. has no parent.

Overrides:treeCopyNoTransform in class NumericLiteral

Returns:: dangling copy of the subtree at this node
Source: Declared in /home/jesper/git/extendj/ASTNode at line 90

public DoubleLiteral treeCopy()

Create a deep copy of the AST subtree at this node. The subtree of this node is traversed to trigger rewrites before copy. The copy is dangling, i.e. has no parent.
