Fields

Modifier and Type	Field and Description
static String	BINDING_SETS_SOURCE An optional attribute specifying the source IBindingSet[] for the index build operation.

Field Detail

HASH_JOIN_UTILITY_FACTORY

static final String HASH_JOIN_UTILITY_FACTORY

A mandatory attribute specifying the IHashJoinUtilityFactory from which this operator obtains a IHashJoinUtility to be used by this operator. This factory is invoked once, the first time this operator is evaluated. The obtained IHashJoinUtility reference is attached to the IQueryAttributes and accessed there on subsequent evaluation passes for this operator.

NAMED_SET_SOURCE_REF

static final String NAMED_SET_SOURCE_REF

An optional attribute specifying the source named solution set for the index build operation. Normally, the hash index is built from the solutions flowing through the pipeline. When this attribute is specified, the hash index is instead built from the solutions in the specified named solution set. Regardless, the solutions flowing through the pipeline are copied to the sink once the hash index has been built.

BINDING_SETS_SOURCE

static final String BINDING_SETS_SOURCE

An optional attribute specifying the source IBindingSet[] for the index build operation. Normally, the hash index is built from the solutions flowing through the pipeline. When this attribute is specified, the hash index is instead built from the solutions in the specified IBindingSet[]. Regardless, the solutions flowing through the pipeline are copied to the sink once the hash index has been built.
