Methods
Name | Description |
---|---|
get
(name, defaultValue)
|
Retrieves the value of the environment variable with the given name ,
or a default value if the variable doesn't exist.
|
opBinaryRight
(name)
|
Identify whether a variable is defined in the environment. |

|
toAA
()
|
Copies all environment variables into an associative array. |
factory
(classname)
|
Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor. |
opCmp
(o)
|
Compare with another Object obj. |
opEquals
(o)
|
Test whether this is equal to o .
The default implementation only compares by identity (using the is operator).
Generally, overrides and overloads for opEquals should attempt to compare objects by their contents.
A class will most likely want to add an overload that takes your specific type as the argument
and does the content comparison. Then you can override this and forward it to your specific
typed overload with a cast. Remember to check for null on the typed overload.
|
toHash
()
|
Compute hash function for Object. |
toString
()
|
Convert Object to a human readable string. |
