public interface Variable extends java.io.Serializable
A variable bridge is a container for storing scalars. A variable bridge is nothing more than a container. It is possible to use a new variable container to alter how scalars are stored and accessed. All scalars, scalar arrays, and scalar hashes are stored using this system.
A Variable bridge is installed by creating a new script variable manager with the new variable bridge. The variable manager is then installed into a given script.
ScriptVariables variableManager = new ScriptVariable(new MyVariable()); script.setScriptVariables(variableManager);
Sleep scripts can share variables by using the same instance of ScriptVariables. A Variable bridge can be used to create built in variables. Every time a certain scalar is accessed the bridge might call a method and return the value of the method as the value of the accessed scalar.

Method Summary
All Methods Instance Methods Abstract Methods Modifier and Type Method Description Variable
createInternalVariableContainer()
returns which variable environment is used to store non-global / non-local variables.Variable
createLocalVariableContainer()
returns which variable environment is used to temporarily store local variables.Scalar
getScalar(java.lang.String key)
returns the specified scalar, if scalarExists says it is in the environment, this method has to return a scalarScalar
putScalar(java.lang.String key, Scalar value)
put a scalar into this variable environmentvoid
removeScalar(java.lang.String key)
remove a scalar from this variable environmentboolean
scalarExists(java.lang.String key)

Method Detail
-
scalarExists
boolean scalarExists(java.lang.String key)
true if a scalar named key exists in this variable environment
-
getScalar
Scalar getScalar(java.lang.String key)
returns the specified scalar, if scalarExists says it is in the environment, this method has to return a scalar
-
putScalar
Scalar putScalar(java.lang.String key, Scalar value)
put a scalar into this variable environment
-
removeScalar
void removeScalar(java.lang.String key)
remove a scalar from this variable environment
-
createLocalVariableContainer
Variable createLocalVariableContainer()
returns which variable environment is used to temporarily store local variables.
-
createInternalVariableContainer
Variable createInternalVariableContainer()
returns which variable environment is used to store non-global / non-local variables. this is also used to create the global scope for a forked script environment.
