Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`XMLDeserializer`	`createDeserializer()`	Returns an instance of the XMLDeserializer that can be used to deserialize project resources.
`java.util.List<EdgeEdition>`	`getEdgeEditions()`	Returns a list of currently available Edge editions (either licensed or in trial).
`com.google.common.eventbus.EventBus`	`getEventBus()`	This is a generic event bus that can be used by any part of Ignition within a single scope (jvm)
`FunctionFactory`	`getExpressionFunctionFactory()`	Returns the core function factory used by expressions.
`LicenseState`	`getLicenseState(java.lang.String moduleId)`	Returns the license state for the given module
`LogFilterSettings`	`getLoggingManager()`
`java.lang.Object`	`getModule(java.lang.String id)`	Returns the hook class for another module, used for modules that deal with each other's models.
`ScriptManager`	`getScriptManager()`	Returns the ScriptManager that can be used to execute Python scripts.
`TagManager`	`getTagManager()`	Returns the manager that provides access to Ignition's tag system.

- Method Detail
  - getTagManager
```
TagManager getTagManager()
```
    Returns the manager that provides access to Ignition's tag system.
  - getScriptManager
```
ScriptManager getScriptManager()
```
    Returns the ScriptManager that can be used to execute Python scripts.
  - createDeserializer
```
XMLDeserializer createDeserializer()
```
    Returns an instance of the XMLDeserializer that can be used to deserialize project resources. Note that this is the only safe way to obtain an instance of XMLDeserializer, because the context will pass the new deserializer around to all loaded modules, giving them a chance to initialize any custom deserialization deletes on it first.
  - getExpressionFunctionFactory
```
FunctionFactory getExpressionFunctionFactory()
```
    Returns the core function factory used by expressions. Includes extension functions registered by modules.
  - getModule
```
java.lang.Object getModule(java.lang.String id)
```
    Returns the hook class for another module, used for modules that deal with each other's models. Example: The reporting plugin's designer hook uses this to get FactoryPMI's palette.
  - getLicenseState
```
LicenseState getLicenseState(java.lang.String moduleId)
```
    Returns the license state for the given module
  - getEdgeEditions
```
java.util.List<EdgeEdition> getEdgeEditions()
```
    Returns a list of currently available Edge editions (either licensed or in trial). Does not check if any required modules are installed and running.
  - getEventBus
```
com.google.common.eventbus.EventBus getEventBus()
```
    This is a generic event bus that can be used by any part of Ignition within a single scope (jvm)
  - getLoggingManager
```
LogFilterSettings getLoggingManager()
```
