getParameterType

Returns the expected type of the parameter.

Contract

The parameter type must conform to the following rules:

• It must be an interface.
• It must contain only getter-like and setter-like methods.
• There must be one getter corresponding to exactly one setter, with matching value types.

For each getter-like method:

• The name must start with "get" or "is", followed by an uppercase letter.
• It must have no parameters.
• The return type must not be void.

For each setter-like method:

• The name must start with "set", followed by an uppercase letter.
• It must have exactly one parameter.
• The return type must be void.

Example

Here is an example of a valid parameter type declaration:

public interface MyParameter {
    String getValue();
    void setValue(String value);

    boolean isFlag();
    void setFlag(boolean value);
}
