public ELResolver getELResolver()

Implements abstract jakarta.el.ELContext.getELResolver.

Doc from jakarta.el.ELContext.getELResolver.

Retrieves the ELResolver associated with this context.

The ELContext maintains a reference to the ELResolver that will be consulted to resolve variables and properties during an expression evaluation. This method retrieves the reference to the resolver.

Once an ELContext is constructed, the reference to the ELResolver associated with the context cannot be changed.

Returns:ELResolver

The resolver to be consulted for variable and property resolution during expression evaluation.
