Method Detail

getTerm

public Term getTerm()

Returns:

Term associated with this entry of the index object graph

getAssociatedDocuments

public InstantiatedTermDocumentInformation[] getAssociatedDocuments()

Meta data per document in which this term is occurring. Ordered by document number.

Returns:

Meta data per document in which this term is occurring.

seekCeilingDocumentInformationIndex

public int seekCeilingDocumentInformationIndex(int target)

Finds index to the first beyond the current whose document number is greater than or equal to target, -1 if there is no such element.

Parameters:

target - the document number to match

Returns:

-1 if there is no such element

seekCeilingDocumentInformationIndex

public int seekCeilingDocumentInformationIndex(int target,
                                               int startOffset)

Finds index to the first beyond the current whose document number is greater than or equal to target, -1 if there is no such element.

Parameters:

target - the document number to match

startOffset - associated documents index start offset

Returns:

-1 if there is no such element

seekCeilingDocumentInformationIndex

public int seekCeilingDocumentInformationIndex(int target,
                                               int startOffset,
                                               int endPosition)

Finds index to the first beyond the current whose document number is greater than or equal to target, -1 if there is no such element.

Parameters:

target - the document number to match

startOffset - associated documents index start offset

endPosition - associated documents index end position

Returns:

-1 if there is no such element

binarySearchAssociatedDocuments

public int binarySearchAssociatedDocuments(int target)

binarySearchAssociatedDocuments

public int binarySearchAssociatedDocuments(int target,
                                           int offset)

binarySearchAssociatedDocuments

public int binarySearchAssociatedDocuments(int target,
                                           int offset,
                                           int length)

Parameters:

target - value to search for in the array

offset - index of the first valid value in the array

length - number of valid values in the array

Returns:

index of an occurrence of key in array, or -(insertionIndex + 1) if key is not contained in array (insertionIndex is then the index at which key could be inserted).

getAssociatedDocument

public InstantiatedTermDocumentInformation getAssociatedDocument(int documentNumber)

Navigates to the view of this occurrences of this term in a specific document. This method is only used by InstantiatedIndex(IndexReader) and should not be optimized for less CPU at the cost of more RAM.

Parameters:

documentNumber - the n:th document in the index

Returns:

view of this term from specified document

field

text

public final java.lang.String text()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getTermIndex

public int getTermIndex()

setTermIndex

public void setTermIndex(int termIndex)
