List of createMethodExpression() Examples

Examples of createMethodExpression()

com.sun.el.lang.ExpressionBuilder.createMethodExpression()
javax.el.ExpressionFactory.createMethodExpression()
Parses an expression into a {@link MethodExpression} for later evaluation. Use this methodfor expressions that refer to methods. If the expression is a String literal, a MethodExpression is created, which when invoked, returns the String literal, coerced to expectedReturnType. An ELException is thrown if expectedReturnType is void or if the coercion of the String literal to the expectedReturnType yields an error (see Section "1.16 Type Conversion"). This method should perform syntactic validation of the expression. If in doing so it detects errors, it should raise an ELException. @param context The EL context used to parse the expression. The FunctionMapper and VariableMapper stored in the ELContext are used to resolve functions and variables found in the expression. They can be null, in which case functions or variables are not supported for this expression. The object returned must invoke the same functions and access the same variable mappings regardless of whether the mappings in the provided FunctionMapper and VariableMapper instances change between calling ExpressionFactory.createMethodExpression() and any method on MethodExpression. Note that within the EL, the ${} and #{} syntaxes are treated identically. This includes the use of VariableMapper and FunctionMapper at expression creation time. Each is invoked if not null, independent of whether the #{} or ${} syntax is used for the expression. @param expression The expression to parse @param expectedReturnType The expected return type for the method to be found. After evaluating the expression, the MethodExpression must check that the return type of the actual method matches this type. Passing in a value of null indicates the caller does not care what the return type is, and the check is disabled. @param expectedParamTypes The expected parameter types for the method to be found. Must be an array with no elements if there are no parameters expected. It is illegal to pass null. @return The parsed expression @throws ELException Thrown if there are syntactical errors in the provided expression. @throws NullPointerException if paramTypes is null.
