Method Detail

create

public IValueExpression<? extends IV> create(BOpContextBase context,
                                    GlobalAnnotations globals,
                                    Map<String,Object> scalarValues,
                                    ValueExpressionNode... args)

Description copied from interface: FunctionRegistry.Factory

Create an IValueExpression instance.

Specified by:

create in interface FunctionRegistry.Factory

Parameters:

context - The BOpContextBase required to evaluate IValueExpressions. This is used if we need to statically evaluate an IValueExpression during query optimization. During query execution the ContextBindingSet will convey this information.

globals - The global annotations, including the lexicon namespace.

scalarValues - The scalar arguments (used by some IAggregates).

args - The function arguments.

Returns:

The IValueExpression.

See Also:

create() was refactored to pass in the {@link BOpContextBase} to allow correct resolution of the {@link LexiconRelation} and {@link ILexiconConfiguration} in order to properly evaluate {@link IValueExpression}s during query optimization.
