Field Summary

Fields

Modifier and Type	Field and Description
static int	ITEM_IDENTIFIER PUBLIC: Value type indicating that the result value is an item identifier and should be used to look up the corresponding topic map object.
static int	OBJECT_ID PUBLIC: Value type indicating that the result value is an object id and should be used to look up the corresponding topic map object.
static int	OBJECT_VALUE PUBLIC: Value type indicating that the result value should be represented as-is (as an object).
static int	OCCURRENCE_URI PUBLIC: Value type indicating that the result value is an external occurrence value identifier and should be used to look up the corresponding occurrence objects.
static int	STRING_VALUE PUBLIC: Value type indicating that the result value should be represented as a string.
static int	SUBJECT_IDENTIFIER PUBLIC: Value type indicating that the result value is a subject identifier and should be used to look up the topic that has that subject identifier.
static int	SUBJECT_LOCATOR PUBLIC: Value type indicating that the result value is a subject locator and should be used to look up the topic that has that subject locator.

Method Detail

getValueType

int getValueType()

PUBLIC: Returns type of values returned by the search result. See constants declared in this class.

getResult

SearchResultIF getResult(String query)

PUBLIC: Returns the String value of the field. Note that null is returned if the field has a reader set.

setModuleURI

void setModuleURI(String moduleURI)

PUBLIC: Called by the query engine before using the instance to pass the module URI to the searcher. No specific behaviour is required from the searcher.

setPredicateName

void setPredicateName(String predicateName)

PUBLIC: Called by the query engine before using the instance to pass the name of the predicate (the part after the colon in the QName) to the searcher. No specific behaviour is required from the searcher.

setTopicMap

void setTopicMap(TopicMapIF topicmap)

PUBLIC: Called by the query engine before using the instance to pass the topic map being queried to the predicate. No specific behaviour is required from the searcher.

setParameters

void setParameters(Map parameters)

PUBLIC: Called by the query engine before using the instance to pass the parameters in the module URI to the searcher. The map will contain {"foo" : "bar"} if the URI ends in "?foo=bar". No specific behaviour is required from the searcher.
