Method Detail

matches

public boolean matches(java.lang.Object actual)

Description copied from interface: IArgumentMatcher

Returns whether this matcher accepts the given argument.

Like Object.equals(), it should be aware that the argument passed might be null and of any type. So you will usually start the method with an instanceof and/or null check.

The method should never assert if the argument doesn't match. It should only return false. EasyMock will take care of asserting if the call is really unexpected.

Specified by:

matches in interface IArgumentMatcher

Parameters:

actual - the argument

Returns:

whether this matcher accepts the given argument.

appendTo

public void appendTo(java.lang.StringBuffer buffer)

Description copied from interface: IArgumentMatcher

Appends a string representation of this matcher to the given buffer. In case of failure, the printed message will show this string to allow to know which matcher was used for the failing call.

Specified by:

appendTo in interface IArgumentMatcher

Parameters:

buffer - the buffer to which the string representation is appended.
