Advanced-Apex-Programming Apex constructs: support for single inheritance interfaces template support control flow structures operators variable declarations Apex concepts: Execution Contexts Static Variables Bulk Patterns Limits Execution Context An execution context has two characteristics: It defines the scope and lifetime of the static variables It defines the context for those governor limits that are reset between execution contexts.
There is a limit to the size of memory heap you can use in an execution context. Ramifications of the execution context: You can have multiple triggers on an event, but have no control over the order in which they execute. Limits are shared within an Execution Context, thus you may be sharing limits with other code over which you have no control and which may be added after yours is built and tested.
Workflows can impact the order and execution context in unpredictable ways. Static Variables Static variables are maintained throughout an execution context, and are unique to an execution context. You know when the execution context starts. Generally, cant know when it ends.
