Interface ELInterpreter
- All Known Implementing Classes:
- ELInterpreterFactory.DefaultELInterpreter,- ELInterpreterTagSetters
public interface ELInterpreter
Defines the interface for the expression language interpreter. This allows
 users to provide custom EL interpreter implementations that can optimise
 EL processing for an application by , for example, performing code generation
 for simple expressions.

Method Details- 
interpreterCallString interpreterCall(JspCompilationContext context, boolean isTagFile, String expression, Class<?> expectedType, String fnmapvar) Returns the string representing the code that will be inserted into the servlet generated for JSP. The default implementation creates a call toPageContextImpl.proprietaryEvaluate(String, Class, jakarta.servlet.jsp.PageContext, org.apache.jasper.runtime.ProtectedFunctionMapper)but other implementations may produce more optimised code.- Parameters:
- context- The compilation context
- isTagFile-- trueif in a tag file rather than a JSP
- expression- a String containing zero or more "${}" expressions
- expectedType- the expected type of the interpreted result
- fnmapvar- Variable pointing to a function map.
- Returns:
- a String representing a call to the EL interpreter.
