Class TeaBindings

java.lang.Object
  com.pdmfc.tea.engine.TeaBindings

All Implemented Interfaces:

java.util.Map<java.lang.String,java.lang.Object>, javax.script.Bindings

public class TeaBindings
extends java.lang.Object
implements javax.script.Bindings

The javax.script.Bindings interface allows Java code to access (get, set, remove, list, etc...) variable bindings for Tea code. In Tea, this is implemented in the base class com.pdmfc.tea.runtime.SContext, com.pdmfc.tea.runtime.STeaRuntime.

Up to Tea 3.2.1, SContext is optimized for speed of execution, and does not support unsetting (undefining) variables or listing variables. As such, methods related to these features throw the java.lang.UnsupportedOperationException.

Field Detail

_runtime

protected com.pdmfc.tea.runtime.STeaRuntime _runtime

The top level runtime SContext. (Please see Tea javadoc for actual details.)

_importDirList

protected java.util.List _importDirList

List of directories (or resource URLs) to be used as import directories. It will be initialized by default from the Tea core configuration, but it can be manipulated using the getImportDirList() method.

Constructor Detail

TeaBindings

public TeaBindings()

_runtime will be initialized on 1st execution attempt, as we are not allowed to throw a ScriptException here. _importDirList is initialized from Tea core configuration.

Returns:

_importDirList. This is the string list of directories/resource URLs that Tea will search to import a file. At the present, _importDirList is initialized in the constructor with the Tea core dir. When the 1st script is run, the Tea interpreter will search for an init.tea file in every directory, and execute it.
