ResourceInterface

interface ResourceInterface

ResourceInterface is the interface that must be implemented by all Resource classes.

Methods

string
__toString()

Returns a string representation of the Resource.

Details

string __toString()

Returns a string representation of the Resource.

This method is necessary to allow for resource de-duplication, for example by means of array_unique(). The string returned need not have a particular meaning, but has to be identical for different ResourceInterface instances referring to the same resource; and it should be unlikely to collide with that of other, unrelated resource instances.

Return Value

string A string representation unique to the underlying Resource
