Method Detail

getToken
BooleanValued getToken(int index)
Description copied from interface:TokenSequence
Gets the value at the specified position.- Specified by:
getToken
in interfaceScalarTokenSequence
- Specified by:
getToken
in interfaceTokenSequence
- Parameters:
index
- the index of the token- Returns:
- the value
-
getBoolean
boolean getBoolean(int index)
Gets the value of the specified token as aboolean
.- Parameters:
index
- the position of the token in the sequence- Returns:
- the value of the token. If the
token is null valued,
false
is returned.
-
getValues
void getValues(int start, boolean[] values, boolean[] nulls, int offset, int length)
Gets the values and null indicators for a range of tokens.- Parameters:
start
- the starting index of the rangevalues
- an array into which to place element valuesnulls
- an array into which to place null indicator valuesoffset
- the starting offset into the target arrays. That is,elements[offset]
andnulls[offset]
will get the value and null indicator respectively of the token at positionstart
, and so on.length
- number of tokens to get
-
newValueIterator
BooleanValuedIterator newValueIterator()
Description copied from interface:TokenSequence
Creates an iterator over the non-null values of this sequence. The iterator will automatically be reset as modifications are made to the sequence.- Specified by:
newValueIterator
in interfaceScalarTokenSequence
- Specified by:
newValueIterator
in interfaceTokenSequence
- Returns:
- an newly-created iterator over the non-null values of this sequence.
