List of insertParameterTypes() Examples

Examples of insertParameterTypes()

java.lang.invoke.MethodType.insertParameterTypes()
Finds or creates a method type with additional parameter types. Convenience method for {@link #methodType(java.lang.Class,java.lang.Class[]) methodType}. @param num the position (zero-based) of the inserted parameter type(s) @param ptypesToInsert zero or more new parameter types to insert into the parameter list @return the same type, except with the selected parameter(s) inserted @throws IndexOutOfBoundsException if {@code num} is negative or greater than {@code parameterCount()} @throws IllegalArgumentException if any element of {@code ptypesToInsert} is {@code void.class}or if the resulting method type would have more than 255 parameter slots @throws NullPointerException if {@code ptypesToInsert} or any of its elements is null
