Method Detail

getToken

BooleanValued getToken(int index)

Description copied from interface: TokenSequence

Gets the value at the specified position.

Specified by:

getToken in interface ScalarTokenSequence

Specified by:

getToken in interface TokenSequence

Parameters:

index - the index of the token

Returns:

the value

getBoolean

boolean getBoolean(int index)

Gets the value of the specified token as a boolean.

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 range

values - an array into which to place element values

nulls - an array into which to place null indicator values

offset - the starting offset into the target arrays. That is, elements[offset] and nulls[offset] will get the value and null indicator respectively of the token at position start, 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 interface ScalarTokenSequence

Specified by:

newValueIterator in interface TokenSequence

Returns:

an newly-created iterator over the non-null values of this sequence.
