CodingConventions.Proxy (Closure Compiler v20180506 API)

java.lang.Object
- com.google.javascript.jscomp.CodingConventions.Proxy

All Implemented Interfaces:

CodingConvention, java.io.Serializable

Direct Known Subclasses:

ChromeCodingConvention, ClosureCodingConvention, GoogleCodingConvention

Enclosing class:

CodingConventions
```
public static class CodingConventions.Proxy
extends java.lang.Object
implements CodingConvention
```
A convention that wraps another. When you want to support a new library, you should subclass this delegate, and override the methods that you want to customize. This way, a person using jQuery and Closure Library can create a new coding convention by creating a jQueryCodingConvention that delegates to a ClosureCodingConvention that delegates to a DefaultCodingConvention.

                                                  boolean iCheckTypes)
```
    Description copied from interface: CodingConvention
    
    A Bind instance or null. When seeing an expression exp1.bind(recv, arg1, ...); we only know that it's a function bind if exp1 has type function. W/out type info, exp1 has certainly a function type only if it's a function literal. If (the old) type checking has already happened, exp1's type is attached to the AST node. When iCheckTypes is true, describeFunctionBind looks for that type. The new type inference does not yet attach types to nodes, but we can still use type information in describeFunctionBind by passing true for callerChecksTypes.
    
    Specified by:
    
    describeFunctionBind in interface CodingConvention
    
    callerChecksTypes - Trust that the caller of this method has verified that the bound node has a function type.

```
    Description copied from interface: CodingConvention
    
    Builds a CodingConvention.Cache instance from the given call node and returns that instance, or null if the Node does not resemble a cache utility call.
    This should match calls to a cache utility method. This type of node is specially considered for side-effects since conventionally storing something on a cache object would be seen as a side-effect.
