Properties

• property LanguageOverride as %String(VALUELIST=",python,objectscript,basic");

Optional setting. Sets the compilation language at level of activity. To be useful, this will differ from the main BPL language.
Example 1: When the overall BPL is generating in ObjectScript mode, this setting can allow a specific BPL Code block activity to accomodate Embedded Python source code.
Example 2: When the overall BPL is generating in ObjectScript mode, this setting can allow a specific BPL Assignment activity expression to accomodate Embedded Python code expression.

• property Parent as Ens.BPL.Node;

This holds a reference to the parent node of this node. Only the root node of the parse tree will have no parent

Methods

• method DisplayName() as %String

Provide a user readable string which identifies this node

• method GenerateCode(pCompiler As Ens.BPL.Compiler) as %Status

• method GenerateXML(pStream As %BinaryStream) as %Status

• method NormalizeAttribute(pAttr)

Normalize Attribute

• method Validate(ByRef pStatus As %Status, pContext As Ens.BPL.ValidationContext) as %Status

Perform a sanity check on the nodes in the parse tree
