Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`Object`	`add(Object prefix, Object output)`	Eg add("foo", "bar") -> "foobar"
`Object`	`common(Object output1, Object output2)`	Eg common("foo", "foobar") -> "foo"
`Object`	`getNoOutput()`	NOTE: this output is compared with == so you must ensure that all methods return the single object if it's really no output
`static NoOutputs`	`getSingleton()`
`String`	`outputToString(Object output)`
`Object`	`read(DataInput in)`
`Object`	`subtract(Object output, Object inc)`	Eg subtract("foobar", "foo") -> "bar"
`void`	`write(Object prefix, DataOutput out)`
