Member Function Documentation

◆ createRuntime()

AbstractExpressionValueSourceRuntimePtr kanzi::AbstractExpressionValueSource::createRuntime ( ExpressionBindingSourceRuntime & host )

Creates a runtime for this expression value source.

Parameters

host	Host expression binding source runtime.

Returns: The created expression value source runtime.

◆ convertToBindingSource()

BindingSourcePtr kanzi::AbstractExpressionValueSource::convertToBindingSource ( )

inline

Converts this expression value source to a matching binding source.

Used to make simple bindings based on expression value sources loaded from disk.

Returns: New binding source matching this expression value source.

◆ createRuntimeOverride()

virtual AbstractExpressionValueSourceRuntimePtr kanzi::AbstractExpressionValueSource::createRuntimeOverride ( ExpressionBindingSourceRuntime & host )

protectedpure virtual

Implementation-dependent runtime creation.

Parameters

host	Host expression binding source runtime.

Returns: The created expression value source runtime.

Implemented in kanzi::DataSourceExpressionValueSource, kanzi::ObjectPropertyExpressionValueSource, kanzi::RenderPropertyExpressionValueSource, and kanzi::VariableExpressionValueSource.
